N2 - A Gram-negative, aerobic, neutrophilic, moderately halophilic bacterial strain, HS225T, was isolated from seawater samples around the Zhoushan Archipelago, Zhejiang Province, China. The isolate grew optimally in media with 5.0 % NaCl, at pH 7.0-8.0 and at 25-30 °C. The predominant fatty acids were C16:0ω9c, C16:0, C12:0 3-OH and C18:1ω9c. The genomic DNA G + C content was 59.0 mol%. Based on 16S rRNA gene sequence analysis, the isolate was found to be affiliated to the genus Marinobacter. Strain HS225T exhibited closest phylogenetic affinity to Marinobacter koreensis DD-M3T (98.1% 16S rRNA gene sequence similarity). DNA-DNA relatedness data and DNA G + C contents as well as physiological and biochemical test results allowed the genotypic and phenotypic differentiation of strain HS225T from closely related species. Therefore, it is proposed that strain HS225T represents a novel species of the genus Marinobacter, for which the name Marinobacter pelagius sp. nov. is proposed. The type strain is HS225T (=CGMCC 1.6775T =JCM 14804T).
