Abstract
In this study, we report a novel Gram-negative bacterium, designated as strain CS412T, isolated from deep-sea sediment collected in a cold seep area of the South China Sea. Growth of strain CS412T occurred at 4–40 °C (optimum, 28 °C), pH 5.0–11.0 (optimum, pH 6.0) and with 0–19 % (w/v) NaCl (optimum, 1–2 %). Phylogenetic analysis based on 16S rRNA gene sequence data indicated that strain CS412T belonged to the genus Marinobacter . The closest phylogenetic neighbours of strain CS412T were Marinobacter pelagius HS225T (96.9 %), Marinobacter szutsaonensis NTU-104T (96.8%), Marinobacter santoriniensis NKSG1T (96.4%) and Marinobacter koreensis dd-M3T (96.3 %). The genomic DNA G+C content of strain CS412T was 58.0 mol%. The principal respiratory quinone was ubiquinone-9 (Q-9). The polar lipids of CS412T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, aminophospholipidand and four glycolipids. The major fatty acids of CS412T contained cyclo-C19 : 0ω8c, C16 : 0, C18 : 1ω7c and C18 : 1ω7c 11-methyl. The results of phylogenetic, physiological, biochemical and morphological analyses suggested that strain CS412T represents a novel species of the genus Marinobacter , and the name Marinobacter fonticola sp. nov. is proposed with the type species CS412T (=CCTCC AB 2019197T=KCTC 72475T).
