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-1-85^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}ω5c 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).
