Abstract A novel bacterial strain, designated Q15T, was isolated from sediments obtained from the Bohai Sea in China and subjected to a polyphasic taxonomic study. Cells of strain Q15T were Gram-stain-negative, strictly aerobic rods that produced circular, flat, orange colonies. Phylogenetic analysis based on 16S rRNA gene sequences revealed that Q15T was affiliated with the genus Carboxylicivirga in the family Marinilabiliaceae of the phylum Bacteroidetes. Strain Q15T differed genotypically from the type strains of the three recognized species of this genus (Carboxylicivirga taeanensis MEBiC 08903T, Carboxylicivirga mesophila MEBiC 07026T and Carboxylicivirga linearis FB218T) and shared 94.0-95.2 % 16S rRNA gene sequence similarity with them. The DNA G+C content of strain Q15T was 44.7 mol%. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 0 3-OH, and menaquinone MK-7 was the main respiratory quinone. Polar lipids contained phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid and other unknown lipids. Based on the data from the current polyphasic analysis, a novel species, Carboxylicivirga flava sp. nov., is hereby proposed with Q15T (=CICC 23923T=KCTC 42707T) as the type strain.
