| Abstract |
An aerobic, Gram-negative, non-motile, yellow-pigmented bacterium, strain KMM 3046(T), was isolated from a deep-sea brittle star from the Fiji Sea and was subjected to a polyphasic taxonomic analysis. Strain KMM 3046(T) grew at 5-32 degrees C and in the presence of 1-12 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone and 3-OH i16 : 0, 3-OH i17 : 0 and 3-OH a17 : 0 as the major fatty acids. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KMM 3046(T) forms a distinct evolutionary lineage within the family Flavobacteriaceae (phylum Bacteroidetes), displaying 92.3-91.9 % sequence similarity with respect to Salegentibacter species. On the basis of the phenotypic and phylogenetic data, strain KMM 3046(T) represents a novel genus and species of the family Flavobacteriaceae, for which the name Marixanthomonas ophiurae gen. nov., sp. nov. is proposed. The type strain of Marixanthomonas ophiurae is KMM 3046(T) (=NRIC 0684(T)=JCM 14121(T)).
