Abstract

On the basis of phenotypic, genotypic characteristics and analysis of 16S rRNA gene sequences, a novel species belonging to the genus is described. A non-pigmented, motile, Gram-negative bacterium designated R10SW13 was isolated from sea water samples collected in Chazhma Bay (Sea of Japan, Pacific Ocean). The novel organism mainly grew between 4 °C and 37 °C, was neutrophilic and slightly halophilic, tolerating up to 10 % NaCl. Strain R10SW13 was haemolytic and was able to degrade starch and Tween 80 and to degrade gelatin and agar weakly, but did not degrade casein. Phosphatidylethanolamine (44·3±0·9 %) and phosphatidylglycerol (55·7±0·9 %) were the predominant phospholipids. The major fatty acids formed were typical for the genus , including 16 : 0, 16 : 1-7 and 18 : 1-7. The G+C content of the DNA was 43·4 mol%. DNA–DNA hybridization experiments showed 38–53 % binding with the DNAs of type strains of phylogenetically related species of the genus , namely: , , , , ‘ subsp. ’ and ‘’. Based on these results, a novel species, sp. nov., is proposed, with strain R10SW13 (=KMM 3600=KCTC 12195=LMG 22532) as the type strain.
