... To determine the effect of light on growth and carotenoid accumulation, cultivation of bacteria in 500 mL baffled shake flasks was conducted using blue (455 nm) LED light as it was reported previously [38]. The level of illuminance for the experiment was in a range of 470-680 lx. ...

... net/ cohne lla. html) which isolated from various environments, including rhizospheric soil (Jiang et al. 2019;Wang et al. 2015), freshwater green alga (Lee and Jeon 2017), arctic tundra soil (Jiang et al. 2012), buffalo faeces (Khianngam et al. 2012), bark (Meng et al. 2019), haematite ore (Mayilraj et al. 2011), fresh water (Shiratori et al. 2010), wild grass fermentation broth (Won et al. 2022), siberian permafrost (Kudryashova et al. 2018), volcanic pond (Cho et al. 2007) and maize callus cultures (Johnson et al. 2021). During the diversity and novelty study of bacterium in geothermal environment of Tengchong City, Yunnan province, China, the strain designated as YIM B05605 T was isolated from Hamazui hot spring. ...

... The Bartonellae isolated in the present study did not show pili or flagella at SEM, which was confirmed by the absence of genes encoding adhesin (BadA) and flagella (FlaA and FlaB). The absence of pili or flagellum is shared with other rodent-associated Bartonella species, such as B. vinsonii [56], B. japonica, B. silvatica [57], B. heixianziensis [58] and B. machadoae [10]. Differently, B. bacilliformis, B. schoenbuchensis, B. capreoli, B. chomelii, B. clarridgeiae and B. rochalimae have flagella. ...

... Acetivibrio clariflavus (basonym: Clostridium clariflavum, Hungateiclostridium clariflavum) is a Gram-positive, thermophilic, cellulolytic cellulosome-forming bacterium, isolated from an anaerobic sewage sludge (Shiratori et al. 2009). Analysis of the A. clariflavus cellulosome has shown that the GH30 enzymes (Clocl_1795, Clocl_2746) were highly abundant in all cellulosome fractions examined (Artzi et al. 2015). ...

... Based on 16S rRNA gene or genome sequences, four genera including Filimonas, Deminuibacter, Arvibacter and Foetidibacter show a close evolutionary relationship with strain SYSU DXS3180 T . The genus Filimonas proposed by Shiratori et al. [2] contains five species: Filimonas lacunae [2], Filimonas endophytica [3], Filimonas zeae [4], Filimonas aquilariae [5] and Filimonas effuse [6]. The genus Arvibacter was first proposed by Chaudhary and Kim [7] with two species, namely Arvibacter flaviflagrans as the type species of the genus and the other strain Arvibacter aurantiibacter [8] was reclassified from Filimonas aurantiibacter [9]. ...

... Symbiobacterium thermophilum, the main genus of Firmicutes detected in the studied samples, was effectively characterized for the first time by Ohno et al. [45,46]. It is a microaerophilic heterotrophic bacterium that can grow under both microaerobic and hypoxic conditions, but it thrives under low oxygen tension [47]. ...

... Dialysis membrane is commonly used to filter molecules of various molecular weights (Himmelfarb et al., 1998 Vienken andBowry, 2008). Furthermore, it was used to culture symbiotic bacteria with the assistance of associate microorganisms or to evaluate tumor growth affected by mechanical stress by positioning spheroid in dialysis membrane bags (Ueda et al., 2002Montel et al., 2011. We used dialysis membrane bags to incubate Salmonella in plant-and in soil-based media without contaminations originating from the plant tissue or the soil. ...

... Acidogenic bacteria can be found in the phyla Firmicutes, Bacteroidetes, Proteobacteria, and Actinobacteria. Several species, including Clostridium (Firmicutes), Peptococcus (Firmicutes), Bifidobacterium (Actinobacteria), Desulfovibrio (Proteobacteria), Corynebacterium (Actinobacteria), Bacillus (Firmicutes), Pseudomonas (Proteobacteria), and Desulfobacter (Proteobacteria), have been identified and separated from AD [16]. In the next stage these VFAs are converted into acetic acids by means of acetogenic bacteria [17]. ...

... They are unable to reduce sulfate or sulfite to hydrogen sulfide. Sugihara et al. showed that Anaerobaculum-related species were dominant bacteria 38 . They concluded that Anaerobaculum-related species were able to degrade propionate. ...

... In contrast, negatively affected OTUs belonged to the genera Cellulosilyticum, Sporanaerobacter, S50_wastewater-sludge_group, Alkalibaculum, and UCG-010_NA. Lutispora thermophila, the only species of its genus so far, is described to be proteolytic and unable to use carbohydrates and was isolated from a thermophilic biogas reactor (Shiratori et al., 2008). Therefore, it can be assumed that the presence of Lutispora spp. was supported by proteinaceous parts of fungal biomass and its intermediates. ...
