Summary: Two anaerobic, mesophilic bacteria SF3(T) and ASD5510 were isolated from human feces in different countries. Strain SF3(T) showed high sequence similarity with strain ASD5510 and a similar strain Aminipila butyrica DSM 103574(T) based on 16S rRNA gene analysis. Strain SF3(T) exhibited a Gram-stain-positive morphology and grew optimally under specific conditions. Based on phenotypic, phylogenetic, and phylogenomic evidence, strain SF3(T) represents a novel species in a novel genus named Hominibacterium faecale gen. nov., sp. nov.

Summary: Two new genera, Neglectibacter gen. nov. and Scatolibacter gen. nov., were identified from stool samples using the culturomics approach, with strains Marseille-P2265(T) and Marseille-P3890(T) being the type strains of Neglectibacter timonensis gen. nov., sp. nov. and Scatolibacter rhodanostii gen. nov., sp. nov., respectively. Genomic comparisons with closely related species revealed lower dDDH, OrthoANI, and AAI values, indicating these strains represent novel taxa within the family Oscillospiraceae.

Summary: The study describes a thermophilic, strictly anaerobic, Gram-stain-negative bacterium strain S15T isolated from oily sludge in Shengli oilfield, China. Physiological characteristics, ecological information, and taxonomical classification of strain S15T are discussed, leading to the proposal of a new genus and species, Thermosynergistes pyruvativorans gen. nov., sp. nov. with strain S15T as the type strain. Additionally, a new family, Thermosynergistaceae fam. nov., is suggested based on the unique characteristics of the strain.

Summary: Waterbodies such as lakes and ponds are fragile environments influenced by human activities. This study found that during a cyanobacterial bloom event in a municipal duck pond, members of the Planctomycetes phylum were significantly enriched in the cyanobacteria-attached fraction. Separate datasets based on isolated DNA and RNA indicated considerable differences in abundance and activity of planctomycetal families during the cyanobacterial bloom.

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: Strain LMG 31809 T was isolated from a top soil sample in Belgium and classified as a rare biosphere bacterium that occurs at low abundances in multiple soil and water ecosystems. It represents a new species within a new genus, Govania unica gen. nov., sp. nov, belonging to the class Alphaproteobacteria. The strain is strictly aerobic and uses organic acids and possibly aromatic compounds as growth substrates. Its whole-genome sequence has a size of 3.21 Mbp with a G + C content of 58.99 mol%.

Summary: A novel Gram-stain-negative, aerobic coccus with exopolysaccharide (EPS) production ability was isolated from coastal sediment of Xiaoshi Island, Weihai, China under the selective pressure of ofloxacin and norfloxacin. This marine isolate was proposed to be a new species named Pelagicoccus enzymogenes sp. nov. The EPS produced by the strain NFK12(T) may contribute to its tolerance against the inhibitory effects of ofloxacin and norfloxacin.
