Abstract:
A Sphingomonas-like bacterium, strain KC7(T), was isolated from a marine crustacean specimen obtained from the Sea of Japan and subjected to a polyphasic study. Comparative 16S rRNA gene sequence analysis positioned the novel strain in the genus Sphingomonas as an independent lineage adjacent to a subclade containing Sphingomonas trueperi LMG 2142(T), Sphingomonas pituitosa EDIV(T) and Sphingomonas azotifigens NBRC 15497(T). Strain KC7(T) shared highest 16S rRNA gene sequence similarity (96.1 %) with S. trueperi LMG 2142(T), Sphingomonas dokdonensis DS-4(T) and S. azotifigens NBRC 15497(T); similarities to strains of other recognized Sphingomonas species were lower (96.0-93.9 %). The strain contained sphingoglycolipid and the predominant fatty acids were C(16 : 1), C(16 : 0) and C(18 : 1); 2-OH C(14 : 0) was the major 2-hydroxy fatty acid. Previously, these lipids have been found to be characteristic of members of the genus Sphingomonas sensu stricto. On the basis of phylogenetic analysis and physiological and biochemical characterization, strain KC7(T) represents a novel species of the genus Sphingomonas, for which the name Sphingomonas japonica sp. nov. is proposed. The type strain is KC7(T) (=KMM 3038(T) =NRIC 0738(T) =JCM 15438(T)).
