title: Polaribacter gangjinensis sp. nov., isolated from seawater.
abstract: A strictly aerobic, orange-pigmented and Gram-staining-negative bacterium, designated K17-16(T), was isolated from seawater of Gangjin Bay, Korea. Comparative 16S rRNA gene sequence analysis revealed that strain K17-16(T) was a member of the genus Polaribacter in the family Flavobacteriaceae and showed 94.0-95.6 % sequence similarity with the type strains of recognized species of the genus Polaribacter. The G+C content of the genomic DNA was 34.6 mol% and the major respiratory lipoquinone was MK-6. The major polar lipids detected were phosphatidylethanolamine, three unidentified amino-group-containing lipids and an unidentified aminophospholipid. The predominant cellular fatty acids were iso-C(15 : 0) (15.4 %), C(15 : 0) (12.4 %), summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c; 10.6 %), C(15 : 1)ω6c (9.8 %) and iso-C(15 : 0) 3-OH (8.6 %). On the basis of phenotypic and genotypic data, strain K17-16(T) represents a novel species in the genus Polaribacter, for which the name Polaribacter gangjinensis sp. nov. is proposed. The type strain is K17-16(T) ( = KCTC 22729(T) = JCM 16152(T)).
