Abstract:
A Gram-negative-staining, non-motile, non-spore-forming, aerobic and rod-shaped bacterial strain, DPG-138(T), was isolated from seawater on the southern coast in Korea. Strain DPG-138(T) grew optimally at 30 °C and in the presence of 2-3 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain DPG-138(T) fell within the cluster comprising the type strains of four species of the genus Marivita (sequence similarity values of 97.8-98.2 %). The DNA G+C content was 59.9 mol%. The predominant ubiquinone of strain DPG-138(T) was Q-10, typical for the genus Marivita. The cellular fatty acid profiles of strain DPG-138(T) and type strains of four species of the genus Marivita were similar with C(18 : 1)ω7c as the most common fatty acid. The major polar lipids in strain DPG-138(T) were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and one unidentified aminolipid. Differential phenotypic properties and genetic distinctiveness of strain DPG-138(T) demonstrated that this strain is distinguishable from all four recognized species of the genus Marivita. On the basis of the data presented, strain DPG-138(T) is considered to represent a novel species of the genus Marivita, for which the name Marivita geojedonensis sp. nov. is proposed. The type strain is DPG-138(T) ( = KCTC 23882(T) = CCUG 62112(T)).
