Foreword
The vast, white expanse of the ice-covered Antarctic continent, seemingly devoid of life.
When such images come to mind we often forget about the extraordinary abundance of
life just beneath the ice, particularly microorganisms, surviving and playing a fundamental
role in the functioning of the Antarctic ecosystems. The abundance and diversity of
microbial life in such extreme aquatic and terrestrial environments have intrigued
scientists for over a century. However, amidst the silence and solitude of the Antarctic we
have begun to see dramatic changes in the environment, with climate change and the
significant impacts of human activities in the region becoming ever more apparent in
recent years.
The International Medical University’s (IMU) foray into polar research first began with
Prof Chu Wan Loy’s passion for tropical and polar algae research. Scientists from the IMU
have since joined in the exploration and study of these extraordinary organisms, expanding
into research on bacteria, viruses, parasites and fungi. Research efforts include how these
microorganisms contribute to the maintenance and delicate balance of the Antarctic
ecosystem and their responses to the changing climate.In this book, we describe the
IMU’s endeavour in polar research, in memory of Prof Chu’s vision and dedication to not
only scientific exploration, but also education and a shared effort to understand the
consequences of global warming.

In comparison to diplomatic and political involvement,
Malaysia’s scientific endeavour in Antarctica started relatively
late in 1997. The breakthrough came when New Zealand
offered the use of Scott Base in Antarctica in 1997 for
Malaysia to undertake research. This became the catalyst for
the Malaysian Cabinet to commission the Academy of
Sciences Malaysia (ASM) to develop the Malaysian Antarctic
Research Program (MARP). MARP was established in 1998
and the young Antarctic program was given abig task to focus
on climate change and biodiversity in Antarctica.
The first Malaysian scientific field research in the Antarctic
was undertaken on 13 to 25 October 1999 in Scott Base,
Antarctica. MARP received an injection of MYR10 million under
the 8th Malaysian Plan (2000-2005)to develop resilient and
innovative researchers in Antarctic Science. During this period,
the MARP started extensive international collaborations with
Antarctic research bodies such as Antarctica New Zealand
(ANZ), Australian Antarctic Division (AAD), British Antarctic
Survey (BAS), Instituto Antártico Argentino (IAA), South Africa
National Antarctic Program (SANAP), Korea Polar Research
Institute (KOPRI), and National Centre for Antarctic and Ocean
Research (NCPOR), India. The bilateral agreements with
national programmes have facilitated the logistic
arrangements for field work in Antarctica and technology
transfers which both benefited the development of Antarctic
research in Malaysia.

Brief History of Malaysia’s Involvement in
Antarctica
Antarctica is the coldest and windiest continent, located at the southernmost part of the globe.
Despite being approximately 10,000 km apart, Malaysia’s interest in Antarctica can be traced to
nearly 40 years ago.In 1983, the then Prime Minister of Malaysia, Tun Dr Mahathir Mohamad
drew the attention of the world by raising the “Question of Antarctica” in the United Nations
General Assembly (UNGA). It is the first official diplomatic initiative that debated the
exclusivity of the Antarctic Treaty System (ATS) represented only by the developed nations.
Tun Dr Mahathir called for the opening of the ATS to allow underdeveloped and developing
countries to participate in the decision-making process regarding Antarctica and to share the
resources of the continent.
Malaysia’s position on Antarctica shifted in the 1990’s, especially after the signing of the
Protocol on Environmental Protection to the Antarctic Treaty (Madrid Protocol) in 1991. The
agreement specifies the protection of the Antarctic environment and prohibits all activities
relating to mineral resources except scientific exploration. Malaysia was active in advocating
the protection of Antarctica, for instance, expressing concern over the overharvesting of krill
and the illegal, unreported and unregulated (IUU) fishing off the Antarctic coast.

Malaysia’s efforts in Antarctic research have been recognised internationally. In 2004, MARP
was admitted as an Associate Member of the Scientific Committee of Antarctic Research
(SCAR) at the 28th SCAR Meeting at Bremerhaven, Germany. MARP has also been invited to
become a consultative member of the Joint Committee on Antarctic Data Management
(JCADM), an arm of SCAR responsible for the collation and dissemination of scientific
information gathered by all research under SCAR. MARP is also a member of the Asian
Forum on Polar Science (AFOPS) and has contributed significantly in the International Polar
Year (IPY 2007/2008) not only in the form of research, but also through outreach and
education.
Twenty eight years since “Question of Antarctica”, Malaysia finally acceded to the Antarctic
Treaty System as aNon-Consultative member, the same year when His Majesty,
The Yang di-Pertuan Agong, Tuanku Mizan Zainal Abidin visited Antarctica. Sultan Mizan
also facilitated the establishment of the Sultan Mizan Antarctic Research Foundation or
Yayasan Penyelidikan Antartika Sultan Mizan (YPASM) in June 2012 to promote and develop
national and international collaborations in the research and conservation of polar regions,
especially in the Antarctic continent. On 15 August 2016,Malaysia finally acceded to the
Madrid Protocol, five years after signing the Treaty. This marked a great progress in
Malaysia’s endeavour in Antarctic research, policy and conservation.

Since operation, YPASM has played an important
role in connecting Malaysian researchers with
scientific communities in the regions and globally.
The foundation provides a fellowship scheme for
Malaysian young Polar researchers to conduct short
research attachment at established Polar
institutions, as well as research grants to support
the continuation of Polar research in Malaysia.It is
noteworthy that IMU researchers are among the
inauguration recipients of the YPASM Antarctic
fellowship. Other than scientific research, the
foundation also organises education and outreach
programmes such as polar science camps, sharing
sessions, contests and exhibitions for students and
the public to nurture the interest in polar science.
Shortly after the setting up of YPASM, the Smart
Partnership Initiative was introduced. The founding 8
members include Universiti Sains Malaysia,
Universiti Malaysia Sabah, University of Malaya,
Universiti Teknologi Mara, Universiti Kebangsaan
Malaysia, Universiti Malaysia Terengganu, Universiti
Putra Malaysia and the IMU. Each participating
university is obliged to contribute MYR55,555 to
YPASM annually for five years with amatching grant
of MYR388,885 from YPASM offsetting more than
half the overall costs.

The IMU’s Endeavour in Polar Research
Being amedical university, the IMU’s involvement in Antarctic research may have raised a
few eyebrows. It is easy to forget that the health of the environment that we are living in, as
well as the health of the animals that share the same space with us are important elements
of overall public health. The notion that the environment can influence human health is not
new. For instance, the ancient Greeks had defined health as astate of dynamic equilibrium
between the internal and the external environments. Furthermore, throughout the ancient
civilisation, the management of pollutants such as human waste had been the priority in the
planning and establishment of human settlements (e.g. construction of bathroom, latrines,
water drains). Additionally, the strong associations between disease, seasonality and
climate are regularly observed. For example, water-borne diseases such as cholera,
leptospirosis and typhoid fever are generally more prevalent during the rainy season.
With the recognition of the inter-relationships between climate, animals and humans in
health, there is an increasing emphasis on “One Health”.Based on the WHO, “One Health is
an approach to designing and implementing programmes, policies, legislation and research
in which multiple sectors communicate and work together to achieve better public health
outcomes”.In line with this approach, the IMU’s researchers had embarked on the journey to
deepen our understanding on the impact of environmental changes on the biota of
Antarctica, and to search for clues of their potential link to human health. The Antarctic is a
perfect natural laboratory to study the impact of environmental perturbations due to its
simple ecosystems, and the fact that it is among the regions that experience a faster rate of
warming.
IMU’s research on Antarctica can be briefly categorised based on the studied organisms.
Work has been conducted on the five groups of microoorganisms, namely algae, bacteria,
viruses, parasites and fungi.

Algae
The IMU’s foray into research on Antarctic algae
began with two flagship projects awarded by the
Ministry of Science, Technology and Innovation
(MOSTI) in 2014, under the Antarctic Flagship
Programme led by Prof DatoDr Azizan Abu Samah,
University of Malaya. Under the flagship projects, a
number of IMU undergraduate and postgraduate
research projects were developed and funded,
including studies on Antarctic bacteria, parasites,
viruses and fungi.
The first project titled ‘Biomarkers of Polar and Lower
Latitudes Microbes in Relation to Heavy Metal Stress’
(MYR819,902)was led by Prof Chu Wan Loy, under the
Flagship Programme theme ‘Diversity and Adaptation
of Microbes: A Cross Latitudinal Study’. The project
aimed to assess the effects of heavy metals on
oxidative stress response and metabolomic profiles of
microalgae isolated from Signy Island, Antarctica.
Although Antarctica is known to be the last pristine
continent on earth, it is not free from heavy metal
contamination. The major source of heavy metal
pollution in Antarctica is mainly due to anthropogenic
activities, especially near research stations.

To collect samples for the
project, Dr Chan Kok Keong
was a member of the project
team that joined the expedition
to Signy Research Station,
Antarctica, organised by the
British Antarctic Survey (BAS)
in 2015.
Dr Dang Nguk Ling completed her PhD titled ‘Effects of heavy metals on oxidative stress response and metabolomics profiles of
Antarctic algae’ in 2020 under Prof Chu’s supervision as part of Prof Chu’s YPASM flagship project.
Dr Chan successfully collected soil samples from
various locations with biological contamination,
namely those with prolonged human activities, heavy
metal contamination and wildlife (penguin, seal and
giant petrel) activities.
The microorganism profiles of the contaminated
locations were then compared with those of pristine
sites on the sub-Antarctic Signy Island. A collection
of soil microalgae was subsequently established
from the samples collected during the expedition.
Morphological characterisation and phylogenetic
studies on the microalgae have been conducted.
Selected microalgae from the collection have also
been used for toxicity testing of heavy metals such
as copper and lead.

The second project was led by Dr Wong
Chiew Yen, titled ‘Physiological and
genomic responses of microalgae to
climate changes across a global
gradient’ (MYR827,600) under the theme
‘An Integrated Approach: Microbes and
Response to Climate Change’. The
project was in collaboration with
Prof Chu, Prof Phang Siew Moi and
Prof Lim Phaik Eem (University of
Malaya), Prof Pete Convey (BAS) and
YPASM.

Dr Wong Chiew Yen
One of the seriously debated environmental issues today is
the impact of climate change, particularly related to
increased temperature and ultraviolet radiation (UVR). The
elevated anthropogenic greenhouse gases are expected to
lead to an increase in the average global surface
temperatures over the next century ranging anywhere from
1.8 to 4.0°C (IPCC, 2007). Increasing levels of UVR have been
reported in many parts of the world including Antarctica and
the adjacent geographic regions (southern parts of South
America and Australia), as well as the Arctic region.
Changes in the global environment, especially global warming
and ozone depletion, which results in the increase of UVR and
temperature can have far-reaching impacts on organisms
especially microalgae in the Antarctic, affecting their
physiological processes and productivity. Such impacts on
microalgae are of particular interest as they form the basis of
the food webs in the Antarctic ecosystem. Thus, the research
project focused on comparing the physiological response of
microalgae from different geographical regions to the effects
of increased temperature and UVR.
In addition, the application of transcriptomics
approaches on microalgae exposed to UVR and
temperature provides insight on the relevant genes and
genetic responses that are involved in responding to
environmental stress. This information is fundamentally
important for the understanding of algal adaptation to
climatic and environmental changes. The objectives of
this project are closely aligned with the aims of the
recently-approved Scientific Committee on Antarctic
Research (SCAR) International Scientific Research
Program, Antarctic Thresholds Ecosystem Resilience
and Adaptation. This project therefore provides a timely
and important opportunity to place Malaysian Antarctic
research firmly in the mainstream of the international
research priorities identified by SCAR.

YPASM Research Grant 2020:Phytoremediation Potential of
Antarctic Microalgae on Diesel Hydrocarbons
The latest (at time of writing) research grant for Antarctic research
was awarded to Dr Wong Chiew Yen under the Smart Partnership
Initiative.In collaboration with Prof Chu and Dr Kok Yih Yih (IMU),
A/Prof Dr Siti Aqlima Ahmad (UPM), Prof Pete Convey (BAS),
A/Prof Dr Azham Zulkharnain (Shibaura Institute Technology,
Japan) and Dr Claudio Gomez-Fuentes (Universidad de
Magallanes, Chile/ Centro de Investigación y Monitoreo Ambiental
Antártico) (CIMAA), the project will run from 2020 and aims to
identify the degradation potential of microalgae isolated from
Antarctica.
Hydrocarbon pollution in Antarctica is derived from various origins
such as catastrophic oil spill events, chronic fuel leakage and from
local effluent, and has contaminated some of Antarctica’s near-to-
pristine land over the past few decades. The hydrocarbon
composition of diesel is known to be toxic and harmful to
terrestrial and marine ecosystems and biota, further exacerbated
due to its persistence. Despite increasing knowledge about
contamination in Antarctica due to increased human pressure,
clean-up (remediation) of polluted sites is still in its infancy, in part
owing to the extreme environment. Remediation through
application of physical machinery would be laborious and costly
due to the harsh conditions, as well directly damaging to the fragile
terrestrial ecosystems, whilst remediation using chemical
dispersants is itself a potential environmental hazard and should
be critically considered.

Malaysia (UPM).
Preliminary testing for phytoremediation using Antarctic microalgae.
Phytoremediation is now emerging as a sustainable
technique for the treatment of organic and inorganic
contaminants. The ability of Antarctic freshwater
algae to remediate diesel hydrocarbons in an axenic
state has not been thoroughly studied, alone or in
combination with characterisation of the abiotic
factors that limit algal growth. Such studies have
the potential to take advantage of the cold-adapted
physiology of native Antarctic microbes in
developing realistic and practicable remediation
approaches, as well as helping to address the
limitations imposed by the Antarctic Treaty System
which bans the import and introduction of non-native
microbes to the Antarctic environment.
The project aligns with the Integrated Science to
Inform Antarctic and Southern Ocean Conservation
(Ant-ICON) proposal for the next generation of SCAR
programmes, which includes a large element of
identifying and mitigating/providing policy advice
pertinent to human impacts on Antarctic
ecosystems. This project will also contribute to
enhancing Malaysia’s footprint in polar research, in
line with the aspiration of the country to attain
consultative status within the Antarctic Treaty.

factors that limit algal growth. Such studies have
the potential to take advantage of the cold-adapted
physiology of native Antarctic microbes in
developing realistic and practicable remediation
approaches, as well as helping to address the
limitations imposed by the Antarctic Treaty System
which bans the import and introduction of non-native
microbes to the Antarctic environment.
The project aligns with the Integrated Science to
Inform Antarctic and Southern Ocean Conservation
(Ant-ICON) proposal for the next generation of SCAR
programmes, which includes a large element of
identifying and mitigating/providing policy advice
pertinent to human impacts on Antarctic
ecosystems. This project will also contribute to
enhancing Malaysia’s footprint in polar research, in
line with the aspiration of the country to attain
consultative status within the Antarctic Treaty.

The cold and arid conditions of Antarctica
have restricted the development of higher
plants on the terrestrial ecosystems. Although
sporadic prevalence of cryptogamic plants
such as mosses and lichens can be detected
in limited biology hotspots during summer, the
vast majority of Antarctica is barren or
covered by permafrost. In such a unique
setting, microorganisms such as bacteria play
avital role in ensuring the functioning of the
ecosystems. What drives the assembly of the
bacterial community and how bacteria
responds to environmental perturbations are
therefore among the key fundamental
questions that need to be addressed to enable
ecological simulation and the design of proper
conservation strategies. Indeed, these form
part of the key research questions highlighted
by the Scientific Committee on Antarctic
Research (SCAR) Antarctic and Southern
Ocean Science Horizon Scan.

Antarctica also constitutes an ideal natural laboratory to test
these theories, without effects of external human influences,
allowing identification of major drivers of bacterial diversity,
function and change. The research will be the first to assess
microbial functions at a continental spatial scale, and the first to
link functional diversity to the underlying chemistry through
nuclear magnetic resonance (NMR) and metabolomics. Findings
will serve as baseline data for future assessments of the impact
of changing environmental conditions, and inform ecological
forecasting; how ecological populations and ecosystems will
change in the future in response to environmental factors such
as climate change. These include effects on crop yield and
potential risks of pathogenic bacteria in the rhizosphere to
animals and humans in the future.
In support of the SCAR Horizon Scan initiative, researchers from
the IMU had initiated a research project to evaluate the
distribution and interaction of microbial communities in the
rhizosphere, titled ‘Molecular evaluation of biogeography and
functional redundancy theory in Antarctic rhizosphere prokaryotic
communities’ (2019-2022, MYR150,000). Rhizosphere is the area
around the plant root (plant-root-soil interface) where numerous
biogeochemical processes take place, pathogenic and beneficial
microorganisms interact, and which constitutes a major
influence on plant growth and health. Using this unit habitat as a
model, the project also seeks to evaluate the validity of bacterial
biogeography and functional redundancy theories by comparing
bacterial community composition and rhizosphere functions
across a large selection of regions in Antarctica.

The expedition lasted for 14 weeks where Dr Alia collected
rhizosphere soil samples across the island. The plant species
beneath which the soil samples were collected from were noted,
comprising of various mosses and lichens as well as the only two
flowering plants native to Antarctica, namely Deschampsia
antarctica and Colobanthus quitensis. The soil samples were
successfully tested and shipped to the UK and subsequently
Malaysia for analysis.
The research is funded by YPASM under the Smart Partnership
Programme, and is in collaboration with Prof Pete Convey (BAS),
Prof David Pearce (University of Northumbria), Dr Nicole Trefault
(Universidad Mayor, Chile), Dr Chong Chun Wie (Monash University,
Malaysia), Dr Mai Chun Wai (IMU), Dr Ivan Yap (Sarawak Research

Dr Fabian developed in-house media to grow Antarctic bacteria
from soil samples collected from Signy Island. His group is also
currently studying both the phenomics (physical and
biochemical traits) of Antarctic bacteria and creating heat maps
to understand their metabolism. Advanced genomics
approaches such as whole genome sequencing of Antarctic
bacteria were also employed to provide further insights into the
molecular evolution, antibiotic resistance, psychrotolerance and
the diversity of the Antarctic bacteria. Through the annotation of
the genomic sequences, Dr Fabian’s research team sought to
identify strains that might lead to the discovery of novel
bioactive compounds with medical applications.

He is intrigued by how the mimivirus is so ubiquitous that
it could be discovered in different parts of the world,
including Antarctica. With the success of isolating
mimivirus from soils in Malaysia, his team used a similar
approach to isolate and detect mimivirus from Antarctica,
particularly soil samples from Signy Island. The genome
of isolated mimivirus will be sequenced to be compared
with those that were discovered from different regions.
Much of the knowledge about the roles of viruses in the
natural environment comes from studies of marine
microbial communities.
Viruses play an important role in infecting and degrading
heterotrophic microbes which later lead to increases in
net respiration, the release of carbon dioxide and nutrient
recycling in the world's oceans. However, the role of
mimivirus in the natural environment remains to be
explored.

using direct smear and a concentration
technique as well as identify the parasites
and parasitic stages using morphological
methods.

For research on fungi, Dr Carolina Santiago studied the effect of Antarctic fungal alkaloid
extracts on indole production in antibiotic resistant Escherichia coli strains. The objective of
her research was to investigate the activity of alkaloid extract on indole production in
antibiotic resistant E. coli strains. According to her research, alkaloidal extract from a
Phoma sp. isolate coded as L21 was found to reduce production of a bacterial signalling
molecule, indole in antibiotic resistant E. coli strains. The compounds from this extract were
deemed to have a potential application in overcoming antibiotic resistance exhibited by
bacteria.

As an educator, Prof Chu was enthusiastic and contributed
significantly to undergraduate medical education in
various roles as alipid biochemist, as respiratory system
coordinator in medicine, in curriculum review for medicine
and as a programme director for medical biotechnology.
For medical biotechnology, his particularly significant
contribution was bringing medicinal plants into the
curriculum.
Prof Chu served as the Dean, School of Postgraduate
Studies (SOPG), IMU from 1 October 2013 till 15 June
2020 and was the Deputy Director, Research, Institute for
Research, Development and Innovation (IRDI), IMU from
18 September 2012 till 31 December 2018.
As Dean, School of Postgraduate Studies, Prof Chu made
important contributions as follows:
1. Introduction of postgraduate diplomas and
certificates to SOPG, previously there were only
masters programmes;
2. Introduction of Online Distance Learning (ODL)
postgraduate programmes;
3. Reviewing the programme to be more flexible to adult
learning and improved governance of programmes;
4. Shortening the masters programme to aminimal one
year programme.
Professor Chu Wan Loy - A humble, kind, passionate and
brilliant scholar who has made significant contributions in
education and research, particularly in the field of algae
research.
Prof Chu presenting his research findings on the human impacts on Antarctica at the 7th Malaysian
International Seminar on Antarctica (MISA7) 2017, Universiti Malaysia Terengganu (UMT).
Prof Chu’s first trip to Antarctica
Prof Chu’s illustrious research journey on algae began when he worked
on tropical algae for his PhD under the supervision of Prof Phang Siew
Moi at the University of Malaya in the 1990s. It was Prof Phang who
encouraged him to continue research in this field and he was one of
two successful Malaysian researchers who was offered a berth by the
Australian Antarctic Division (AAD) to go on a reconnaissance voyage
to Casey Station, Antarctica in 2000.
This was his first trip to Antarctica and due to several delays, Prof Chu
managed to stay on Casey Station for only four days but the
experience and the journey were memorable for him.He collected the
first set of Antarctic polar algae samples on soil, snow and glaciers
from several sites including a penguin rookery and this collection
formed the basis of numerous studies on responses and adaptation of
Antarctic algae to global warming and UVR stress. Such studies are
important to understand the consequences of environmental changes
such as global warming and the widening hole in the ozone layer and
their impact on Antarctica.

The current outlook on mitigation of global warming does not appear promising, with figures in the reduction of anthropogenic greenhouse gas emissions lagging far behind climate goals. A recent environmental report even postulated a high possibility of temperature increase of at least 3 °C by 2100. Despite the low number of human inhabitants in Antarctica, the Antarctic Peninsula was reported as one of the most rapidly warming locations on earth. Many studies have shown that heat stress modulates physiological performance in many species of microalgae; however, studies to elucidate the molecular mechanisms of high-temperature thermotolerance are generally focused on the model species, i.e. Chlamydomonas reinhardtii. Furthermore, previous transcriptomic work in this aspect generally employed the microarray technique and/or involved the tropical or temperate strains, and few were conducted on the polar strains. In this study, RNA-Seq-mediated transcriptomic analysis was undertaken to compare the whole transcriptome profile of an Antarctic Chlorella sp. grown at ambient (4 °C) versus stress-inducing high (33 °C) temperatures and harvested at the 120-h time point. The findings of this study indicated a coordinated response to fine tune balance between energy production and utilisation for biosynthesis by redirecting carbon provision, and the arrest of cell division as a coping mechanism for an intense and relatively long period of stress. The strategies undertaken by this alga in acclimation to heat stress are somewhat similar to the heat stress response of the model species.

Stratospheric ozone depletion has led to increasing levels of ultraviolet radiation (UVR) reaching the Earth’s surface. Elevated UVR, particularly in the high latitudes, potentially causes shifts in species composition and diversity in various ecosystems, consequently altering the biogeochemical cycles. Microalgae are not only ecologically important as primary producers, generating atmospheric oxygen and sequestering carbon dioxide; they are also economically important as sources of health supplement, pigments, biofuel and others. Changes to the size and composition of algal communities can lead to profound impacts to the fisheries productivity. There have been studies on the effects of UVR on the growth, photosynthesis and biochemical composition of microalgae, but limited information on the underlying molecular mechanisms involved in the response and adaptation of microalgae to UVR is available. We employed RNA-seq to quantitatively evaluate and compare the transcriptomes of an Antarctic freshwater Chlorella sp. grown at ambient versus elevated UVR conditions. Differentially expressed genes, relating to the fatty acid degradation, amino acid metabolism, starch and sucrose metabolism and peroxisome pathways, suggest conservation and remobilisation of energy resources, maintenance of newly synthesised protein and inhibition of protein degradation, ensuring membrane lipid homeostasis and regulating antioxidative mechanisms, as the acclimation strategies in response to UVR. These findings expand current knowledge of gene expression in polar Chlorella sp. in response to short-term UVR. Studies on stress tolerance mechanisms are important to understand and predict future impacts of climate change. Genes, proteins and pathways identified from these adaptable polar algae have potentially far-reaching biotechnological applications.

The role of aerial dispersal in shaping patterns of biodiversity remains poorly understood, mainly due to a lack of coordinated efforts in gathering data at appropriate temporal and spatial scales. It has been long known that the rate of dispersal to an ecosystem can significantly influence ecosystem dynamics, and that aerial transport has been identified as an important source of biological input to remote locations. With the considerable effort devoted in recent decades to understanding atmospheric circulation in the south polar region, a unique opportunity has emerged to investigate the atmospheric ecology of Antarctica, from local to continental scales. This concept note identifies key questions in Antarctic microbial biogeography and the need for standardized sampling and analysis protocols to address such questions. A consortium of polar aerobiologists is established to bring together researchers with a common interest in the airborne dispersion of microbes and other propagules in the Antarctic, with opportunities for comparative studies in the Arctic.

The productivity and survival of algae are strongly affected by their physiological and biochemical processes, as well as biotic and abiotic factors in the environment. In recent years, global climate change such as increased temperature and elevated ultraviolet radiation (UVR) due to ozone depletion has huge impact on organisms particularly the ones in the marine ecosystem. It has been demonstrated that the global temperature increased steadily over the last decade, with an average of 0.74°C. In the coming years, climate model projections summarized by the Intergovernmental Panel of Climate Change (IPCC) indicate that average global surface temperature will likely rise a further 0.5 to 1.6°C by 2030, and rising to 1.1 to 6.4°C by 2100. As algae serve as the primary producer of food chain in both marine and terrestrial ecosystems, it is of great significance to understand the impact of temperature change on their physiological and biochemical processes. This review provides the information on how algae respond to temperature change based on their growth, biochemical composition and fatty acid composition.

The global temperature increase has significant implications on the survival of microalgae which form the basis of all aquatic food webs. The aim of this study was to compare the response of similar taxa of microalgae from the Antarctic (Chlamydomonas UMACC 229, Chlorella UMACC 237, and Navicula glaciei UMACC 231), temperate (Chlamydomonas augustae UMACC 247, Chlorella vulgaris UMACC 248, and Navicula incerta UMACC 249), and tropical (C. augustae UMACC 246, C. vulgaris UMACC 001, and Amphiprora UMACC 239) regions to changing temperature. The Antarctic, temperate, and tropical strains were grown over specific temperature ranges of 4 °C to 30 °C, 4 °C to 32 °C, and 13 °C to 38 °C, respectively. The three Antarctic strains survived at temperatures much higher than their ambient regime. In comparison, the tropical strains are already growing at their upper temperature limits. The three Chlorella strains from different regions are eurythermal, with a large overlap on tolerance ranging from 4 °C to 38 °C. The specific growth rate (μ) of the Antarctic Navicula decreased (<0.34 day−1) at temperatures above 4 °C, showing it to be sensitive to temperature increase. If further warming of Earth occurs, N. glaciei UMACC 231 is likely to have the most deleterious consequences than the other two Antarctic microalgae studied. The percentage of polyunsaturated fatty acids (PUFA) decreased with increasing temperature in the Antarctic Navicula. As temperature increases, the growth and nutritional value of this commonly occurring diatom in the Antarctic may decrease, with consequences for the aquatic food web. Of the three Chlamydomonas strains, only the Antarctic strain produced predominantly PUFA, especially 16:3 (48.4–57.2 % total fatty acids).

The growth, biochemical composition and fatty acid profiles of six Antarctic microalgae cultured at different temperatures, ranging from 4, 6, 9, 14, 20 to 30 ∘C, were compared. The algae were isolated from seawater, freshwater, soil and snow samples collected during our recent expeditions to Casey, Antarctica, and are currently deposited in the University of Malaya Algae Culture Collection (UMACC). The algae chosen for the study were Chlamydomonas UMACC 229, Chlorella UMACC 234, Chlorella UMACC 237, Klebsormidium UMACC 227, Navicula UMACC 231 and Stichococcus UMACC 238. All the isolates could grow at temperatures up to 20 ∘C; three isolates, namely Navicula UMACC 231 and the two Chlorella isolates (UMACC 234 and UMACC 237) grew even at 30 ∘C. Both Chlorella UMACC 234 and Stichococcus UMACC 238 had broad optimal temperatures for growth, ranging from 6 to 20 ∘C (μ = 0.19 – 0.22 day–1) and 4 to 14 ∘C (μ = 0.13 – 0.16 day–1), respectively. In contrast, optimal growth temperatures for NaviculaUMACC 231 and Chlamydomonas UMACC 229 were 4 ∘C (μ = 0.34 day–1) and 6–9 ∘C (μ = 0.39 – 0.40 day–1), respectively. The protein content of the Antarctic algae was markedly affected by culture temperature. All except Navicula UMACC 231 and Stichococcus UMACC 238 contained higher amount of proteins when grown at low temperatures (6–9 ∘C). The percentage of PUFA, especially 20:5 in Navicula UMACC 231 decreased with increasing culture temperature. However, the percentages of unsaturated fatty acids did not show consistent trend with culture temperature for the other algae studied.

Changes in gene expression are an important response of Antarctic algae to temperature stress. The objective of this study was to investigate the differential gene expression of the Antarctic alga Chlorella UMACC 234 in response to temperature stress. The RNA was extracted from the cells grown at 4, 20, and 30°C and converted to cDNA by reverse transcription. Differentially expressed genes (DEG) were isolated and identified using the GeneFishing™ DEG Kit (Seegene) with 20 arbitrary annealing control primers (ACP). The bands of interest were excised and purified from the agarose gel and then cloned and sequenced. A total of 22 DEG clones were isolated and identified, with 11 DEG detected only at 30°C and six DEG detected only at 4°C. Three DEG were detected at 4 and 20°C while two were detected at 20 and 30°C. The DEG were associated with functions such as photosynthesis, carbohydrate metabolism, electron transfer, and cell maintenance. Three DEG that showed high degree of similarity with sequences from the database were those code for Photosystem II P680 chlorophyll a apoprotein CP47 (PSII-CP47), aldose 1-epimerase, and a putative oxidoreductase. Real-time PCR analysis showed that the expression of the PSII-CP47 gene increased by threefold at 4°C while that of the aldose 1-epimerase and oxidoreductase genes increased by threefold and eightfold, respectively, at 30°C compared with 20°C (optimal growth temperature).

Elevated temperatures as a consequence of global warming have significant impacts on the adaptation and survival of microalgae which are important primary producers in many ecosystems. The impact of temperature on the photosynthesis of microalgae is of great interest as the primary production of algal biomass is strongly dependent on the photosynthetic rates in a dynamic environment. Here, we examine the effects of elevated temperature on Chlorella strains originating from different latitudes, namely Antarctic, Arctic, temperate and tropical regions. Chlorophyll fluorescence was used to assess the photosynthetic responses of the microalgae. Rapid light curves (RLCs) and maximum quantum yield (Fv/Fm) were recorded. The results showed that Chlorella originating from different latitudes portrayed different growth trends and photosynthetic performance. The Chlorella genus is eurythermal, with a broad temperature tolerance range, but with strain-specific characteristics. However, there was a large overlap between the tolerance range of the four strains due to their “eurythermal adaptivity”. Changes in the photosynthetic parameters indicated temperature stress. The ability of the four strains to reactivate photosynthesis after inhibition of photosynthesis under high temperatures was also studied. The Chlorella strains were shown to recover in terms of photosynthesis and growth (measured as Chl a) when they were returned to their ambient temperatures. Polar strains showed faster recovery in their optimal temperature compared to that under the ambient temperature from which they were isolated.

Microalgae are important biologicalresources that have a wide range of biotechnologicalapplications. Due to their high nutritional value,microalgae such as Spirulina and Chlorella are beingmass cultured for health food. A variety of high-valueproducts including polyunsaturated fatty acids (PUFA),pigments such as carotenoids and phycobiliproteins, andbioactive compounds are useful as nutraceuticals andpharmaceuticals, as well as for industrial applications. Interms of environmental biotechnology, microalgae areuseful for bioremediation of agro-industrial wastewater,and as a biological tool for assessment and monitoring ofenvironmental toxicants such as heavy metals, pesticidesand pharmaceuticals. In recent years, microalgae haveattracted much interest due to their potential use asfeedstock for biodiesel production. In Malaysia, therehas been active research on microalgal biotechnologyfor the past 30 years, tapping into the potential of ourrich microalgal resources for high-value products andapplications in wastewater treatment and assessmentof environmental toxicants. A culture collection ofmicroalgae has been established, and this serves asan important resource for microalgal biotechnologyresearch. Microalgal biotechnology should continue tobe regarded as a priority area of research in this country.
