Arenicella xantha gen. nov., sp. nov., a gammaproteobacterium isolated from a marine sandy sediment.
A Gram-negative, aerobic, yellow-pigmented, rod-shaped, non-motile bacterium, strain KMM 3895T, 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 3895T in the class Gammaproteobacteria, forming a separate branch, sharing 89.5 % sequence similarity with Nitrincola lacisaponensis 4CAT 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 C16:1omega7, iso-C16:0, iso-C18:0 and C18:1omega7 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 3895T 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 3895T (=NRIC 0759T =JCM 16153T).
