Summary: The human gut microbiota is a complex ecological system. In a culturomics study, a novel bacterium strain ICN-92133(T) was isolated from a patient with Crohn's disease, and its classification and phylogeny were determined. This research is significant for enhancing our understanding of the composition and function of gut microbiota.

Summary: The vampyrellids are a major group of predatory amoebae with diverse feeding strategies, playing crucial roles in suppressing soil disease and controlling aquatic algae. A new species, Kinopus chlorellivorus, was found to be a significant grazer causing losses in large-scale Chlorella cultures due to its high feeding ability on Chlorella species.

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: This study describes a new species of heterolobosean amoeba, Euplaesiobystra perlucida, which causes losses in the cultivation of Phaeodactylum tricornutum. This species has the ability to graze on various unicellular and filamentous microalgae and may pose significant problems in large-scale microalgal culture.

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: A novel strain of Cohnella bacterium named Cohnella zeiphila sp. nov. was isolated from a culture of maize callus in Peoria, Illinois, United States. Through phenotypic, phylogenetic, and genomic analysis, the strain was confirmed to be unique within the Cohnella genus. This study also presents genome data for five type strains of Cohnella species, contributing to a better understanding of this genus.

Summary: A gram-negative, aerobic, rod-shaped bacterium called HL-LV01T was isolated from the intestinal tract content of the Pacific white shrimp Litopenaeus vannamei. Based on the 16S rRNA gene sequence analysis, strain HL-LV01T belongs to the genus Maribacter and is most closely related to Maribacter flavus KCTC 42508T. The strain exhibits different genomic characteristics compared to other species in the same genus.

Summary: In this study, two cold-active bacteriophages, ACA1 and ACA2, were isolated from sediment samples taken from the western Arctic Ocean. These phages were able to replicate at a low temperature of 1 degree C and had typical myovirus morphology. The complete genome sequences of ACA1 and ACA2 were very similar, encoding lysogeny-related proteins. The study expands our knowledge of P2-like phage diversity in Pseudoalteromonas and demonstrates their presence in the Arctic niche.
