Abstract
An orange-coloured, rod-shaped, Gram-reaction-negative and aerobic bacterial strain, designated KYW589T, was isolated from seawater collected from Gwangyang Bay, Republic of Korea. The isolate required sea salts for growth. Gliding motility was observed. Flexirubin-type pigments were absent. Major cellular fatty acids (>10 % of the total) were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G, C16 : 0, iso-C15 : 0 3-OH and C18 : 0. The main polar lipids were phosphatidylethanolamine, two unidentified aminolipids and two unidentified lipids. The predominant isoprenoid quinone was MK-6. The DNA G+C content was 38.6±0.7 mol% (mean±sd of three determinations). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain KYW589T belongs to the family Flavobacteriaceae , and was related to the genus Algibacter . Based on data from a study using a polyphasic taxonomic approach, it is proposed that strain KYW589T represents a novel species belonging to the genus Algibacter , for which the name Algibacter aquimarinus sp. nov. is proposed. The type strain is KYW589T ( = KCTC 23928T = JCM 18287T). Reclassification of Pontirhabdus pectinivorans Yi et al. 2011 to the genus Algibacter , as Algibacter pectinivorans comb. nov. (type strain JC2675T = KACC 14153T = JCM 17107T), is also proposed.
