Gangjinia marincola gen. nov., sp. nov., a marine bacterium of the family Flavobacteriaceae.
A novel strictly aerobic, orange-pigmented, Gram-stain-negative bacterium, designated strain GJ16(T), 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(T) formed a distinct lineage within the family Flavobacteriaceae and shared less than 91.2 % 16S rRNA gene sequence similarity with members of the genera Leptobacterium, Zhouia, Winogradskyella, Dokdonia and Krokinobacter. The predominant cellular fatty acids were iso-C(15 : 0) (40.2 %), iso-C(15 : 1) G (12.8 %), iso-C(17 : 0) 3-OH (11.2 %) and C(15 : 0) (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(T) represents a novel species in a new genus in the family Flavobacteriaceae, for which the name Gangjinia marincola gen. nov., sp. nov. is proposed; the type strain is GJ16(T) (=KCTC 22649(T) =JCM 16082(T)).
