Sediminitomix flava gen. nov., sp nov., of the phylum Bacteroidetes, isolated from marine sediment

A novel bacterium designated Mok-1-85(T) was isolated from a marine sediment sample collected from Okinawa Island, Japan. Cells of strain Mok-11-85(T) stained Gram-negative, were catalase- and oxidase-positive and were non-motile. In a neighbour-joining tree based on 16S rRNA gene sequences, the novel strain clustered with the genus Flammeovirga, a member of the family 'Flammeovirgaceae'. The novel isolate shared low 16S rRNA gene sequence similarities (<= 86%) with the members of the genus Flammeovirga and other related taxa. The major isoprenoid quinone was MK-7 and the predominant fatty acids of this organism were iso-C-15:0, C-16:1 omega 5c and C-16:0 3-OH. The G + C content of the DNA was 38 mol%. Combined phylogenetic and physiological data showed that strain Mok-1-85(T) represents a novel genus and species for which the name Sediminitomix flava gen. nov., sp. nov. is proposed. The type strain is Mok-1-85(T) (=NBRC 101625(T)=KCTC 12970(T)=CIP 109411(T)).
