Two spore-forming, facultatively anaerobic, lactic acid bacteria, strains SL153 and SL1153, were isolated from vineyard soil in Korea. Cells of both strains were slightly curved, Gram-positive, motile rods that measured between 1 and 4 μm in length and were approximately 0.5 μm in diameter. Strains SL153 and SL1153 fermented glucose, fructose, mannose and sorbitol, but were negative for nitrate reduction, catalase and oxidase. The predominant cellular fatty acids of the two isolates were iso-C, anteiso-C and anteiso-C. Diaminopimelic acid, glucose, mannose and galactose were determined in their whole-cell hydrolysates. 16S rRNA gene sequences from the two strains were almost identical (99.9 %) and they could be placed in the genus according to phylogenetic analysis. The species most closely related to SL153 were and with 16S rRNA gene similarities of 95.7 and 95.5 %, respectively, with the type strains. Levels of DNA–DNA relatedness between strain SL153 and the type strains of , and were 18.5, 18.0 and 17.0 %, respectively. On the basis of the phylogenetic (16S rRNA gene), chemotaxonomic and phenotypic evidence given in this study, it is proposed that strains SL153 and SL1153 should be assigned to the genus as representatives of the novel species sp. nov. The type strain is SL153 (=KCTC 5376=JCM 14637).
