A Marinomonas-like bacterium, strain KMM 3893T, was isolated from a marine sandy sediment collected close to shore from the Sea of Japan and subjected to a phenotypic and phylogenetic study. Comparative 16S rRNA gene sequence analysis confirmed the novel strain's assignment to the genus Marinomonas. Strain KMM 3893T constituted a separate phyletic line in the genus Marinomonas, sharing <97 % sequence similarity with respect to other recognized Marinomonas species. Chemotaxonomically, strain KMM 3893T contained the predominant fatty acids C18 : 1
7c, C16 : 1
7c and C16 : 0 and had a DNA G+C content of 50.0 mol%. On the basis of the phylogenetic analysis and physiological and biochemical characterization, strain KMM 3893T represents a novel species of the genus Marinomonas, for which the name Marinomonas arenicola sp. nov. is proposed. The type strain is KMM 3893T (=NRIC 0752T =JCM 15737T).
A maximum-parsimony phylogenetic tree based on 16S rRNA gene sequences is available as supplementary material with the online version of this paper.
