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 25–30 °C. predominant fatty acids were C16 : 0 ω9c, 0, C12 3-OH C18 1 ω9c. genomic DNA G+C content 59.0 mol%. Based on 16S rRNA gene sequence analysis, found to be affiliated genus Marinobacter. Strain HS225T exhibited closest phylogenetic affinity Marinobacter koreensis DD-M3T (98.1 similarity). DNA–DNA relatedness data contents as well physiological biochemical test results allowed genotypic phenotypic differentiation of strain closely related species. Therefore, it is proposed that represents a novel species Marinobacter, for which name pelagius sp. nov. proposed. type (=CGMCC 1.6775T =JCM 14804T)
