Two strains, CN44T and CN47T, isolated from marine sediment of the East China Sea, were characterized by using a polyphasic approach. The isolates Gram-negative, strictly aerobic, non-spore-forming rods. chemotaxonomic characteristics these included presence C18 : 1 ω7c, C16 0, iso-C15 0 2-OH and/or ω7c C10 3-OH as major cellular fatty acids Q-8 predominant ubiquinone. DNA G+C contents strains CN47T 62.5 56.3 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain was related to members genus Marinobacterium. most closely described organism type Marinobacterium rhizophilum (95.3 % sequence similarity). Strain showed highest similarity stanieri (97.8 %) <97 other species. level DNA–DNA relatedness between M. DSM 7027T 46 %. On basis phenotypic genotypic properties, represent two novel species within Marinobacterium, for which names nitratireducens sp. nov. (type strain, =CGMCC 1.7286T =JCM 15523T) sediminicola 1.7287T 15524T) are proposed.
