Marinobacter salicampi sp. nov., isolated from a marine solar saltern in Korea

A Gram-negative, motile, rod-shaped, Marinobacter-like bacterial strain, ISL-40^T, was isolated from a marine solar saltern of the Yellow Sea in Korea. The taxonomic position of the novel strain was investigated using a polyphasic approach. Strain ISL-40^T grew optimally at pH 7.0-8.0 and at 30 °C. It contained Q-9 as the predominant ubiquinone. The major fatty acids were C_16:0, C_16:1ω7c and/or iso-C_15:0 2-OH and 10-methyl C_16:0. The DNA G+C content was 58.1 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-40^T belongs to the genus Marinobacter. Strain ISL-40^T exhibited 16S rRNA gene sequence similarity values of 93.5-96.4 % to the type strains of recognized Marinobacter species. The differential phenotypic properties and phylogenetic distinctiveness of strain ISL-40^T revealed that it is separate from recognized Marinobacter species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain ISL-40^T represents a novel species of the genus Marinobacter, for which the name Marinobacter salicampi sp. nov. is proposed. The type strain is ISL-40^T (=KCTC 12972^T=CCUG 54357^T).
