- Abstract
A Gram-stain-negative, strictly aerobic, orange-colored, rod-shaped, chemoheterotrophic bacterium, designated HG732, was isolated from marine sediment in Japan. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel marine strain was affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it shared the highest (94.1 %) sequence similarity with Kriegella aquimaris KMM 3665. The strain could be differentiated phenotypically from related members of the family Flavobacteriaceae. Major fatty acids of strain HG732 were iso-C15:1 G, iso-C15:0 and iso-C17:0 3-OH. The polar lipid profile consisted of phosphatidylglycerol, three unidentidied aminolipids and two unidentified lipids. The DNA G+C content of the strain was determined to be 35.2 mol%, and the major respiratory quinone was identified as menaquinone 6 (MK-6). From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus in the family Flavobacteriaceae, for which the name Aurantibacter crassamenti gen. nov., sp. nov. is proposed. The type strain of A. crassamenti gen. nov., sp. nov. is HG732 (= KCTC 52207 = NBRC 112211).
