sp. nov., isolated from human epidermis.

Five pink-pigmented bacterial strains, isolated from human skin and classified within the genus , were examined. Among them, four were identified as , while strain OT10 was deemed to be a potential novel species. Strain OT10 exhibited characteristics, such as Gram-stain-negative, oxidase positive, motile, strictly aerobic and rod shaped. The cells had multiple flagella at one end, arranged in a lophotrichous pattern. The predominant cellular fatty acids in OT10 were C ω7c/C ω6c and C 2OH; ubiquinone (Q)-10 was identified as the sole quinone. Major polar lipids included phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine and two aminolipids. The G+C content of the genome was determined to be 72.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarities revealed that strain OT10 is closely related to subsp. ATCC 49956 (97.7%), subsp. ATCC BAA-691 (97.7%) and ATCC BAA-692 (97.5%). For the comparative genomic analyses, whole-genome sequencing was also conducted for strain OT10. Considering the chemotaxonomic, genotypic and phenotypic features, as well as the low average nucleotide identity and digital DNA-DNA hybridization values compared to its closest phylogenomic neighbours, OT10 is proposed to be a novel species named sp. nov., with OT10 designated as the type strain (=KCTC 92087 =JCM 34968).
