Psychromonas heitensis sp. nov., a psychrotolerant bacterium isolated from seawater in Japan.
Four bacterial strains, 04HE-4-40, A4I-9, A4I-21 and AK15-027(T), were isolated from Heita Bay off Kamaishi in Japan. Based on 16S rRNA gene sequence analysis, the isolates were placed as a new lineage within the genus Psychromonas. The 16S rRNA gene sequence similarity values between the isolates and type strains of recognized Psychromonas species were less than 97 %. The DNA G+C contents of the isolates were about 38 mol%. The major respiratory quinone was Q-8, and the predominant cellular fatty acids were 16 : 1omega7c and 16 : 0. The isolates were able to grow at 30 degrees C, unlike other Psychromonas species. Based on the results of the phylogenetic analysis and phenotypic characteristics and DNA-DNA hybridization data, the isolates represent a novel species, for which the name Psychromonas heitensis sp. nov. is proposed. The type strain is AK15-027(T) (=MBIC 06898(T)=NCIMB 14416(T)).
