Abstract
A Gram-stain negative, non-motile, and yellow-coloured bacterium, designated 17J28-26T, was isolated from soil in Jeju Island, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 17J28-26T formed a distinct lineage within the family Chitinophagaceae (order Chitinophagales, class Chitinophagia), and is closely related to Flavisolibacter ginsenosidimutans (96.8% 16S rRNA gene sequence similarity), and Flavisolibacter ginsengisoli (96.6%). Growth was observed at 18–37 °C (optimum 30 °C) in R2A medium at pH 7.0. The major cellular fatty acids of strain 17J28-26T were summed feature 3 (C16:1 ω6c and/or C16:1 ω7c), and iso-C15:0. The predominant respiratory quinone was MK-7. The major polar lipid was identified as phosphatidylethanolamine. Based on biochemical, chemotaxonomic and phylogenetic characteristics, strain 17J28-26T represents a novel bacterial species within the family Chitinophagaceae, for which the name Flavisolibacter galbus sp. nov. is proposed. The type strain of Flavisolibacter galbus is 17J28-26T (= KCTC 62222T = JCM 33203T).
