A Gram-negative, aerobic, yellow-pigmented, rod-shaped, non-motile bacterium, strain KMM 3895(T), was isolated from a marine sandy sample collected offshore from the Sea of Japan. Phylogenetic analysis based on the 16S rRNA gene sequence placed strain KMM 3895(T) in the class Gammaproteobacteria, forming a separate branch, sharing 89.5% sequence similarity with Nitrincola lacisaponensis 4CA(T) and 88-87% similarity with the other members of the cluster, including members of Kangiella, Spongiibacter, Alcanivorax and Microbulbifer. The major isoprenoid quinone was Q-8. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, aminophospholipid and an unknown phospholipid. Fatty acid analysis revealed C(16:1)omega 7, iso-C(16:0), iso-C(18:0) and C(18:1)omega 7 as dominant components. The DNA G+C content was determined to be 48.1 mol%. Based on its unique phenotypic characteristics and phylogenetic distance, the marine coastal sediment isolate KMM 3895(T) should be classified as a representative of a novel genus and species, for which the name Arenicella xantha gen. nov., sp. nov. is proposed. The type strain of Arenicella xantha is KMM 3895(T) (=NRIC 0759(T) =JCM 16153(T)).
