Abstract

A Gram-negative, non-pigmented, non-motile, chemoheterotrophic marine bacterium, designated strain IMCC2782, was isolated from a surface seawater sample of the Yellow Sea, Korea. On the basis of 16S rRNA gene sequence analysis and phenotypic and genotypic characterization, strain IMCC2782 is shown to represent a novel species of the genus . Strain IMCC2782 grew at 15–37 °C and tolerated 7.5 % NaCl. Based on 16S rRNA gene sequences, strain IMCC2782 was related most closely to the type strain of (97.1 % similarity) but showed less than 90 % similarity to the type strains of other bacterial species. The predominant fatty acids were mono-unsaturated C and C. The G+C content of the DNA of strain IMCC2782 was 59.6 mol%. A low level of DNA–DNA relatedness (28.1 %) together with several phenotypic characteristics, including enzyme activities, served to differentiate strain IMCC2782 from the type strain of . Therefore, strain IMCC2782 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is IMCC2782 (=KCTC 22683 =NBRC 105824).
