The present research aimed to understand the influence of plant growth-promoting bacteria (PGPB) on various biochemical, nutritional, and pharmaceutical characteristics of Marrubium vulgare plants grown under elevated carbon dioxide (eCO2). To achieve this objective, a pot experiment was carried out, consisting of two treatments, namely: (i) biofer...

Introduction Antimony (Sb), a common rare heavy metal, is naturally present in soils at low concentrations. However, it is increasingly used in industrial applications, which in turn, leads to an increased release into the environment, exerting a detrimental impact on plant growth. Thus, it is important to study Sb effects on plants under the curre...

Due to the growing world population and increasing environmental stress, improving the production, nutritional quality, and pharmaceutical applications of plants has become an urgent need. Therefore, the current research was designed to investigate the impact of seed priming using plant-growth-promoting bacteria (PGPB) along with selenium nanoparti...

To date, several studies have considered the phytotoxic impact of cosmetics and personal care products on crop plants. Nonetheless, data are scarce about the toxic impact of galaxolide [hexahydro-hexamethyl cyclopentabenzopyran (HHCB)] on the growth, physiology, and biochemistry of plants from different functional groups. To this end, the impact of...

Mucormycosis is considered one of the most dangerous invasive fungal diseases. In this study, a facile, green and eco-friendly method was used to biosynthesize silver nanoparticles (AgNPs) using Pseudomonas indica S. Azhar, to combat fungi causing mucormycosis. The biosynthesis of AgNPs was validated by a progressive shift in the color of P. indica...

Tungsten nanoparticles (WNPs) could induce hazard impact on plant growth and development; however, no study investigated their phytotoxicity. On the other hand, plant growth-promoting bacteria (PGPB) can effectively reduce WNPs toxicity. To this end, Nocardiopsis sp. was isolated and employed to mitigate the phytotoxic effect of WNPs on three crops...

The occurrences of Trihalomethanes (THMs) and heterotrophic bacteria were monitored in water samples from different locations “areas”. The water samples we got them water from (El-Shocake RO plant system, Jazan, KSA) over a twelve -month period to investigate the association between (THMs) and heterotrophic bacteria populations. The sampling sit...

In this study, green and eco-friendly biosynthesis of selenium nanoparticles (Se-NPs) were performed using Penicillium expansum ATTC 36200 for multiple biomedical applications. Mycosynthesized Se-NPs were completely characterized using UV, FT-IR, XRD, SEM, and TEM techniques. Se-NPs biosynthesized by P. expansum was characterized as a spherical sha...

Like its bulk counterpart, tungsten (W) nanoparticles (WNPs) could induce environmental hazard to plant growth and yield, however no study investigated their phytotoxicity. On the other hand, plant growth-promoting bacteria (PGPB) can be effectively applied to reduce WNPS toxicity. Therefore, we aimed at investigating the phytotoxic effect of WPNs...

Water safety and security has become a great problem in recent years, as the shortage of water resources in most countries is becoming an increasingly serious issue. Therefore, searching for new water sources or treating contaminated water has become a major requirement to covering the shortage of fresh water. The current study evaluated the impact...

Background: Alzheimer's disease (AD) is characterized by the accumulation and deposition of β-amyloid peptides leading to a progressive neuronal damage and cell loss. Besides several hypotheses for explaining the neurodegenerative mechanisms, oxidative stress has been considered to be one of them. Till date, there is no cure for AD, but the pathog...

The optimized conditions for the production of a protease produced by a thermohaloalkali tolerant Halobacillus strain were determined. The results showed that the optimum temperature for enzyme activity was 65°C and the highest proteolytic activity was obtained at 10% NaCl. Also, the enzyme exhibited proteolytic activity over a broad pH range from...

An extracellular protease was produced by a thermohaloalkali tolerant bacterial strain, designated B300, which was isolated from a salt-affected soil sample collected at Beni-Suef city, Egypt. The bacterial strain was assigned to genus Halobacillus based on the phylogenetic analysis of the 16S rRNA gene. It was found that the protease was produced...
