Flavisolibacter swuensis sp. nov. Isolated from Soil

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.
