Flavisolibacter swuensis sp nov Isolated from Soil

초록

A Gram-staining-negative, non-motile, non-spore-forming, and rod-shaped bacterium designated as strain SR2-4-2(T) was isolated from soil in South Korea. Phylogenetic analysis based on 16S rRNA gene sequence of strain SR2-4-2(T) revealed that it belonged to the genus of Flavisolibacter, family of Chitinophagaceae, and class of Sphingobacteriia. It shared sequence similarities with Flavisolibacter ginsengisoli Gsoil 643(T) (96.4%), Flavisolibacter ginsengiterrae Gsoil 492(T) (96.3%), and Flavisolibacter rigui 02SUJ3(T) (93.0%). Chemotaxonomic data revealed that its predominant fatty acids were iso-C-15:0 (26.4%) and iso-C-17:0 3OH (10.7%). Its major polar lipid was phosphatidylethanolamine (PE) and its predominant respiratory quinone was MK-7. The G+C content of genomic DNA of the strain SR2-4-2(T) DNA was 45.0%. Based on the phylogenetic, chemotaxonomic, and phenotypic data, the strain SR2-4-2(T) (=JCM 19974(T) =KEMB 9004-156(T)) is classified as a type strain of a novel species for which the name of Flavisolibacter swuensis sp. nov. is proposed.
