sp. nov., isolated from marine sediment.

A Gram-stain-variable, rod-shaped, motile bacterial strain, designated S1-20, was isolated from marine sediment of the Yellow Sea in China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-20 was related to the genus and had highest 16S rRNA gene sequence similarities with the type strains of (98.1 %), (97.7 %) and (97.3 %). The predominant cellular fatty acids of strain S1-20 were anteiso-C and anteiso-C. The main menaquinone was MK-7. The genomic DNA G+C content of strain S1-20 was 38.3 mol%. The polar lipids profile contained diphosphatidylglycerol, phosphatidylglycerol, five unidentified phospholipids, one unknown aminophospholipid and an aminolipid. Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain S1-20 is a representative of a novel species of the genus , for which the name sp. nov. is proposed. The type strain is S1-20 ( = LMG 28381 = DSM 29015).
