Abstract 

A Gram-stain-negative, aerobic, non-motile, rod-shaped and pale yellow-pigmented bacterium, designated strain TX0661T, was isolated from an automotive air conditioning system collected in the Republic of Korea. 16S rRNA gene sequence analysis showed that the strain TX0661T was grouped with members of the genus Flavisolibacter and the strain had 98.2-95.3?% 16S rRNA gene sequence similarities to the species of the genus Flavisolibacter. DNA-DNA relatedness between TX0661T and Flavisolibacter ginsenosidimutans KCTC 22818T and Flavisolibacter ginsengisoli KCTC 12657T was less than 30?%. The low levels of DNA-DNA relatedness identified strain TX0661T as a novel species in the genus Flavisolibacter. The strain grew at 28-37?°C (optimum, 37?°C), at pH 6.0-7.0 (optimum, pH 6.5) and in the presence of 0-0.5?% (w/v, optimum, 0.5?%) NaCl. It contained summed feature 3 (C16?:?1ω7c and/or C16?:?1ω6c), iso-C15?:?0 and iso-C17?:?0 3-OH as major fatty acids and MK-7 as the predominant menaquinone. The polar lipid profile revealed that the presence of phosphatidylethanolamine, aminoglycophospholipid, two unidentified aminolipids and two unidentified lipids. The DNA G+C?content of the strain was 49.1?mol%. Based on phenotypic, genotypic and chemotaxonomic data, strain TX0661T represents a novel species in the genus Flavisolibacter, for which the name Flavisolibactermetallilatus sp. nov. (=KACC 19145T=KCTC 52779T=NBRC 111784T) is proposed.
