Flavisolibacter aluminii sp. nov., a novel member of the genus Flavisolibacter isolated from an automotive air conditioning system

摘要

A Gram-stain-negative, aerobic, non-motile, rod-shaped, and yellow-pigmented bacterium, designated strain ID1709~T, was isolated from an automotive air conditioning system collected in Korea. Analysis of 16S rRNA gene sequence similarity showed that strain ID1709~T had 92.2-94.3% similarities with the type strains of members of the genus Flavisolibacter. The major cellular fatty acids were iso-C_(15:0), iso-C_(15:1) G, iso-C_(17:0) 3-OH, and summed feature 3 (C_(16:1) ω7c and/or C_(16:1) ω6c). The predominant respiratory quinone was MK-7. The polar lipids comprised phosphatidylethanolamine, aminoglycophospholipid, two unidentified aminolipids, and three unidentified lipids. The DNA G + C content of the strain was 35.6 mol%. Based on phenotypic, chemotaxonomic, and genotypic data, strain ID1709~T represents a novel species in the genus Flavisolibacter, for which the name Flavisolibacter aluminii sp. nov. (= KACC 19451~T = KCTC 52778~T = NBRC 112870~T), is proposed.
