A Gram-stain-negative, rod-shaped bacterium, designated strain YC7378(T) was isolated from vermicompost (VC) collected at Masan, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain YC7378(T) grew optimally at 30 degrees C and at pH 6.5-8.5. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YC7378(T) belongs to the genus Sphingosinicella in the family Sphingomonadaceae. The most closely related strains are Sphingosinicella soli KSL-125(T) (95.7%), Sphingosinicella xenopeptidilytica 3-2W4(T) (95.6%) and Sphingosinicella microcystinivorans Y2(T) (95.5 W). Strain YC7378(T) contained ubiquinone Q-10 as the major respiratory quinone system and sym-homospermidine as the major polyamine. The major fatty acids of strain Y07378(T) were C-18:1 omega 7C, C-16:1 omega 7C and/or iso-C-15:0 2-OH, C-14:0 2-OH and C-16:0. The major polar lipids were sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The total DNA G+C content was 59.4 mol%. The phenotypic, phylogenetic and chemotaxonomic data showed that strain Y07378(T) represents a novel species of the genus Sphingosinicella, for which the name Sphingosinicella vermicomposti sp. nov. is proposed. The type strain is YC7378(T) (=KCTC 22446(T) =DSM 21593(T)).
