Abstract
Two facultatively anaerobic mesophilic bacteria, strains MEBiC 07026T and MEBiC 08903T, were isolated from two different tidal flat sediments and both strains showed approximately 92.2 % 16S rRNA gene sequence similarity with [Cytophaga] fermentans DSM 9555T. 16S rRNA gene sequence similarity between the two new isolates was 97.5 % but levels of DNA-DNA relatedness between the two were 31.3-31.8 %. Phylogenetic analysis revealed that the two isolates and [Cytophaga] fermentans DSM 9555T were affiliated with the family Marinilabiliaceae in the class Bacteroidia. The dominant fatty acids of strains MEBiC 07026T, MEBiC 08903T and [Cytophaga] fermentans DSM 9555T were branched-type or hydroxylated C15: 0, but [Cytophaga] fermentans DSM 9555T contained a higher proportion of anteiso-branched fatty acids. The two new isolates contained a markedly higher proportion of monounsaturated fatty acids than other members of the family Marinilabiliaceae. The major respiratory quinone of the strains was MK-7. Strains MEBiC07026T and MEBiC08903T utilized a wide range of carboxylic acids whereas [Cytophaga] fermentans DSM 9555T utilized carbohydrates rather than carboxylic acids. The DNA G+C content of the novel strains was about 44 mol% but that of [Cytophaga] fermentans DSM 9555T revealed from the genome sequence was 37.6 mol%. Based on evidence from this polyphasic taxonomic study, a novel genus, Carboxylicivirga gen. nov., is proposed in the family Marinilabiliaceae with two novel species, Carboxylicivirga mesophila sp. nov. with type strain MEBiC 07026T (= KCCM 42978T = JCM 18290T) and Carboxylicivirga taeanensis sp. nov. with type strain MEBiC 08903T (= KCCM 43024T = JCM 19490T). Additionally, [Cytophaga] fermentans DSM 9555T (= ATCC 19072T) is reclassified as Saccharicrinis fermentans gen. nov., comb. nov. © 2014 IUMS.
