Abstract

An aerobic, Gram-negative bacterial isolate, strain DX5-10, was isolated from coastal sediment of the East China Sea. The taxonomy of strain DX5-10 was studied by phenotypic and phylogenetic methods. Strain DX5-10 was motile, formed faint-yellowish colonies and was positive for catalase reaction and weakly positive for oxidase reaction. The nearly complete 16S rRNA gene of strain DX5-10 was obtained and sequence analysis indicated that strain DX5-10 represented an independent lineage within the clade of . Strain DX5-10 was phylogenetically related to members of the genera , , , , , , , and , and the sequence identities among them were less than 95·0 %. The predominant respiratory ubiquinone of strain DX5-10 was Q-10 and the DNA G+C content of strain DX5-10 was 63·3 mol%. Therefore, strain DX5-10 represents a novel species of a novel genus, for which the name gen. nov., sp. nov. is proposed, with the type strain DX5-10 (=CGMCC 1.3455=JCM 12573).
