Summary: A new species of Clostridium, named Clostridium zeae, was isolated from corn silage in Japan. This Gram-negative, strictly anaerobic bacterium has specific growth conditions and unique characteristics in terms of cellular fatty acids and polar lipids. Phylogenetic analysis showed its close relationship with other Clostridium species, but distinctive genomic and phenotypic differences warrant its classification as a new species.

Summary: This study isolated two multifunctional bacteriocin-producing Pediococcus strains from silage samples in Bulgaria, which showed strong antimicrobial activity against Listeria, vancomycin-resistant Enterococcus, and various molds. Metabolomic analysis revealed the production of antifungal metabolites by the strains. This research provides new insights into the potential of Pediococcus strains in controlling pathogens and molds.

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: Two new bacterial strains, Marseille-P2698(T) and Marseille-P2260(T), were isolated from human stools using the culturomic method. These two strains were fully described using the taxonogenomic approach. Marseille-P2698(T) was identified as a Gram-negative, motile, non-spore-forming, rod-shaped bacterium, while Marseille-P2260(T) was identified as a Gram-positive, motile, spore-forming rod-shaped bacterium.

Summary: A Gram-negative strain, RN2-1(T), was isolated from a Korean forest soil sample. It is characterized as aerobic, oxidase-positive, catalase-negative, non-motile, oval/rod-shaped, and can grow in a wide pH and temperature range. The strain belongs to a novel genus, Limobrevibacterium gyesilva gen. nov., sp. nov., and is closely related to Rhodovastum atsumiense G2-11(T). The whole genome analysis and phenotypic data of strain RN2-1(T) support its distinctive phylogenetic position.

Summary: Two novel anaerobic strains, designated AF52-21(T) and CM04-06(T), were isolated from faeces of healthy Chinese donors using a pure culture strategy. Phylogenetic analysis revealed that these strains clustered with Faecalibacterium species, supporting their recognition as two new species within the genus. Genomic analysis showed differences below the proposed species threshold, confirming their uniqueness.

Summary: The genus Coniochaeta belongs to the class Ascomycota and the family Coniochaetaceae. Some species are plant and animal pathogens, while others are involved in human diseases. A new species, Coniochaeta massiliensis, was described and characterised, with genetic and phenotypic analysis showing its uniqueness compared to other species in the genus.

Summary: The two bacterial strains examined in this study were isolated from the stool of a healthy volunteer and the urine of a kidney transplant recipient, respectively. Through analysis of their morphology, biochemistry, and genomic characteristics, they were identified as new members of the Peptoniphilus genus and named Peptoniphilus coli sp. nov. and Peptoniphilus urinae sp. nov.
