AI Article Synopsis
- A new bacterium, named Cryobacterium mesophilum, was discovered in soil from Bigeum Island, South Korea, and is characterized as a Gram-positive, aerobic organism with unique cellular properties.
- The bacterium thrives best at temperatures between 25-28°C and has specific fatty acids, such as anteiso-C15:0 and iso-C16:0, contributing to its cellular structure.
- Phylogenetic analysis shows that Cryobacterium mesophilum is closely related to other members of the Cryobacterium genus, with significant sequence similarity percentages to known species.
Article Abstract
A novel mesophilic, Gram-positive, cream- to pale yellow-pigmented, aerobic bacterium, designated MSL-15T, was isolated from a soil sample collected from Bigeum Island, South Korea. The cells were catalase-positive, motile and irregular rods. The diamino acid content of the cell-wall peptidoglycan was determined to be 2,4-diaminobutyric acid. Strain MSL-15T grew well between 20 and 28 degrees C, with optimum growth occurring at 25-28 degrees C. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0, anteiso-C17 : 0 and iso-C15 : 0. The genomic DNA G+C content was 70.0 mol%. A phylogenetic analysis based on 16S rRNA gene sequences indicated that strain MSL-15T was associated with the genus Cryobacterium and exhibited 96.6 % sequence similarity to Cryobacterium psychrotolerans JCM 13925T and 94.8 % similarity to Cryobacterium psychrophilum JCM 1463T. Phenotypic, chemotaxonomic and phylogenetic data revealed that strain MSL-15T represents a novel species within the genus Cryobacterium, for which the name Cryobacterium mesophilum is proposed. The type strain is MSL-15T (=DSM 19267T=KCTC 19270T).
