Abstract:
A Gram-stain-negative, short-rod-shaped bacterium, designated 22DY03 T , was isolated from a sediment sample collected from the East Pacific Rise. The isolate required NaCl and grew best with 3–7 % (w/v) sea salts at temperature of between 30 and 35 °C at pH 7.0. It formed non-pigmented colonies and produced exopolysaccharide, but did not produce bacteriochlorophyll a . Strain 22DY03 T was positive for hydrolysis of aesculin and Tween 20 and negative for hydrolysis of casein, DNA, gelatin, starch and Tween 40, 60 and 80. The major respiratory quinone was ubiquinone-10. The polar lipid profile consisted of a mixture of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, two unidentified phospholipids and four unidentified polar lipids. The major fatty acids were C 19 : 0 cyclo ω8 c , C 18 : 1 ω7 c and 11-methyl C 18 : 1 ω7 c . The genomic DNA G+C content was 64.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain 22DY03 T should be assigned to the genus Roseivivax . The 16S rRNA gene sequence similarities between the isolate and the type strains of species of the genus Roseivivax were in the range of 94.1–95.8 %. On the basis of phenotypic and genotypic data, it is concluded that strain 22DY03 T represents a novel species of the genus Roseivivax , for which the name Roseivivax pacificus sp. nov. (type strain 22DY03 T = CGMCC 1.12410 T = JCM 18866 T ) is proposed.
