Summary: A novel bacterium strain CAU 1614(T) was isolated from a marine sediment sample collected in the Republic of Korea, belonging to a new genus Halomarinibacterium in the family Flavobacteriaceae. It is a Gram-negative, strictly aerobic, non-motile rod-shaped bacterium with optimal growth conditions at 30 degrees C, pH 7.0, and 2% NaCl. The genetic, phenotypic, and chemotaxonomic characteristics distinguish it as a new species Halomarinibacterium sedimenti gen. nov., sp. nov.

Summary: A novel mesophilic sulfur-disproportionating bacterium named Desulfolithobacter dissulfuricans was isolated from a deep-sea hydrothermal vent chimney in the Izu-Bonin Arc, Japan. This bacterium is able to disproportion elemental sulfur, thiosulfate, and tetrathionate in the presence of ferrihydrite, as well as grow via respiratory hydrogen oxidation coupled to sulfate reduction. Proteomic analysis revealed specific and abundant production of proteins related to tetrathionate reductase during thiosulfate disproportionation. This study provides insights into the diversity of sulfur-disproportionating bacteria in hydrothermal systems.

Summary: The bacterium RKSG073T isolated from Aplysina fistularis off the coast of San Salvador showed optimal growth conditions at 30-37 degrees C, pH 6-7, and with 2-3 % NaCl. Phylogenetic analysis placed it in a clade with its closest relative Aestuariispira insulae AH-MY2T. Based on its distinctiveness, a novel genus and species Curvivirga aplysinae gen. nov., sp. nov. is proposed for RKSG073T.

Summary: This study isolated a novel Gram-negative bacterium Pseudoprevotella muciniphila with mucin-degrading capabilities from the rumen epithelium of Korean cattle. The bacterium showed specific growth conditions and contained unique fatty acids, polar lipids, and respiratory quinones. Functional annotation of the genome revealed potential virulence factors that allow the bacterium to adhere to host cells and evade immune responses.

Summary: Five novel halophilic archaeal strains were isolated from coastal saline sediments and sea salt in China. They demonstrated typical morphology and growth characteristics and showed high similarities with existing species. However, based on genetic and phylogenetic analyses, it is confirmed that these strains represent five new species. This is the first report of a novel haloarchaeon isolated from a marine intertidal zone.

Summary: The microbial potential of crude oil degradation coupled to methane production has attracted attention for microbial enhanced energy recovery. Laboratory incubation experiments under in situ conditions showed successful microbial community capable of methanogenic crude oil degradation. Biological augmentation and stimulation strategies were effective for methane production associated with crude oil degradation, offering a powerful tool for energy recovery from petroleum reservoirs.

Summary: The study identified a novel methoxydotrophic archaeon capable of converting methoxylated aromatic compounds to methane. Transcriptomics and proteomics analysis revealed that the archaeon used an O-demethylation/methyltransferase system similar to acetogenic bacteria. Enzymatic assays indicated a two-step mechanism in which the methyl group is transferred from the methoxy compound to cobalamin and then further transferred to tetrahydromethanopterin.

Summary: The study found that reducing leucine feedback inhibition in the l-leucine synthetic pathway could induce leucine accumulation in yeast cells, thereby increasing the content of fruity flavors in the fermentation process. A specific allele of the LEU4 gene (LEU4(G516S)) was identified to dominantly induce leucine accumulation in yeast cells, including triploid and tetraploid strains. Furthermore, the intracellular amount of branched-chain amino acids was found to be the same between heterozygous and homozygous diploid strains carrying the LEU4(G516S) allele.
