ABSTRACT
A novel Gram-stain-negative, motile, rod-shaped (0.4-0.5×1.0-2.0 µm) strain with one polar flagellum, designated SY39T, was isolated from seawater in Sanya, China. Strain SY39T was able to grow at 15-40 °C (optimum, 35-37 °C), pH 6.5-8.5 (pH 8.0) and 0.5-6.0â% (w/v) NaCl (3.5â%). Chemotaxonomic analysis showed that the isoprenoid quinones were Q-8 (88.6â%) and Q-7 (11.4â%). The dominant fatty acids were C16ââ0 and summed feature 3 (C16ââ1ω7c/C16ââ1ω6c). The polar lipids of strain SY39T consisted of diphosphatidyglycerol, phosphatidylglycerol, phosphatidylethanolamine, one unknown phosphoglycolipid, one unknown glycolipid and two unknown aminophosphoglycolipids. The DNA G+C content of the genomic DNA was 66.5 mol%. The phylogenetic analysis of 16S rRNA gene sequences showed that strain SY39T belongs to the genus Azoarcus with similarity ranging from 92.3 to 95.2â%. Based on the phenotypic, chemotaxonomic and phylogenetic features, strain SY39T is concluded to represent a novel species of the genus Azoarcus, for which the name Azoarcus pumilus sp. nov. is proposed. The type strain is SY39T (=KCTC 62157T=MCCC 1K03430T).
