Abstract

A Gram-stain-negative, coccoid, yellow, non-motile, aerobic bacterium, designated strain S36, was isolated from soil of the Xixi wetland in Zhejiang province, PR China. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain S36 could represent a novel species of genus showing highest similarity to 26DY36 (96.31 % 16S rRNA gene sequence similarity). The temperature, pH and NaCl concentration ranges for growth were 10–37 °C (optimum 32 °C), pH 5.0–10.0 (optimum pH 7.0) and 0.5–3 % (optimum 1 %, w/v), respectively. The predominant respiratory quinone of strain S36 was Q-10. The major fatty acids were C, Cω, Cω and summed feature 3 (Cω and/or iso-C 2-OH). The G+C content of the genomic DNA was 62.7 mol%. These data all support the affiliation of strain S36 to the genus . The polar lipids profile of strain S36 comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified phospholipids and two unidentified glycolipids. The results of physiological and biochemical tests allowed differentiation of strain S36 from other members of the genus . Therefore, strain S36 represents a novel species of the genus , for which the name sp. nov. is proposed; the type strain is S36 (=CGMCC 1.12804=NBRC 110413).
