Abstract
Two novel Psychrobacter-like bacterial strains, JG-219T and JG-220, were isolated from jeotgal, a traditional Korean fermented seafood. Cells of strains JG-219T and JG-220 were Gram-negative, non-motile coccobacilli. Growth of the two strains was observed at 432 °C. They grew optimally in the presence of 25 % (w/v) NaCl. Strains JG-219T and JG-220 contained C18 : 1ω9c and C17 : 1ω8c as the major fatty acids and Q-8 as the predominant ubiquinone. The DNA G+C contents of strains JG-219T and JG-220 were 43·5 and 43·0 mol%, respectively. The two strains showed no difference in their 16S rRNA gene sequences but exhibited minor differences in their phenotypic properties. Strains JG-219T and JG-220 exhibited levels of 16S rRNA gene sequence similarity of 95·298·7 % to the type strains of recognized Psychrobacter species. The mean level of DNADNA relatedness between strains JG-219T and JG-220 was 84·4 %. The two strains exhibited levels of DNADNA relatedness of 1·532·9 % to the type strains of eight phylogenetically related Psychrobacter species. On the basis of phenotypic data and phylogenetic and genetic distinctiveness, the two strains were classified as representing a novel species within the genus Psychrobacter, Psychrobacter cibarius sp. nov. The type strain is JG-219T (=KCTC 12256T=DSM 16327T).
