Abstract

A Gram-negative, rod-shaped bacterium, IG8, was isolated from seawater off the Sanriku coast, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IG8 represented a separate lineage within the genus ; the highest 16S rRNA gene sequence similarity values were found with the type strains of (98.6 %) and (98.4 %). DNA–DNA hybridization values between strain IG8 and the type strains of . (27.9–36.1 %) and (11.3–31.0 %) were clearly below 70 %, the generally accepted limit for species delineation. The DNA GC content of strain IG8 was 66.3 mol%. On the basis of DNA–DNA hybridization, some biochemical characteristics and 16S rRNA gene sequence comparison, it is proposed that the isolate represents a novel species, sp. nov. The type strain is IG8 (=IAM 15450=NCIMB 14280).
