Abstract

A novel strictly aerobic, orange-pigmented, Gram-stain-negative bacterium, designated strain GJ16, was isolated from coastal seawater of Gangjin Bay, the southernmost part of the Korean peninsula, and subjected to a polyphasic taxonomic study. It grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of 3 % NaCl. Comparative 16S rRNA gene sequence analysis revealed that strain GJ16 formed a distinct lineage within the family and shared less than 91.2 % 16S rRNA gene sequence similarity with members of the genera , , , and . The predominant cellular fatty acids were iso-C (40.2 %), iso-C G (12.8 %), iso-C 3-OH (11.2 %) and C (6.6 %). The G+C content of the genomic DNA was 39.4 mol% and the major respiratory isoprenoid quinone was MK-6. On the basis of phenotypic and genotypic data, strain GJ16 represents a novel species in a new genus in the family , for which the name gen. nov., sp. nov. is proposed; the type strain is GJ16 (=KCTC 22649 =JCM 16082).
