sp. nov., isolated from Indian Ocean marine sediment.

A novel Gram-stain-positive, catalase-positive, oxidase-negative, aerobic, non-motile, rod-shaped bacterium, designated strain YIM M12148, was isolated from a marine sediment sample collected from the Indian Ocean. The strain grew optimally at 28 °C, pH 8.0 and in the presence of 1-3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM M12148 belongs to the genus , with the highest sequence similarity to NBRC 15706 (96.12 %). The cell-wall sugars of strain YIM M12148 were rhamnose, ribose, glucose and mannose. The predominant isoprenoid quinones were MK-8 and MK-9. The polar lipids consisted of major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unknown phospholipid and one unknown lipid. Major fatty acids (>5 % of the total) of the novel isolate were anteiso-C, iso-C, iso-C and anteiso-C. The genomic DNA G+C content of strain YIM M12148 was 67.15 mol%. On the basis of genotypic and phenotypic data, it is apparent that strain YIM M12148 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YIM M12148 (=KCTC 29660=DSM 29154).
