Arenimonas taoyuanensis sp. nov., a novel bacterium isolated from rice-field soil in China.
A Gram-stain negative, aerobic, rod-shaped bacterial strain, YN2-31A(T), was isolated from rice-field soil, Taoyuan Village, Yunnan province of China. The bacterium was observed to grow at 20-45 °C (optimum 28 °C), at pH 5.0-10.0 (optimum 7.0), and in the presence of 0-2% (w/v) NaCl (optimum 0-1%). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YN2-31A(T) is most closely related to Arenimonas daejeonensis DSM 18060(T) (96.1%), Arenimonas malthae DSM 21305(T) (95.9%), Arenimonas donghaensis DSM 18148(T) (95.1%), Arenimonas composti DSM 18010(T) (94.8%) and Arenimonas maotaiensis JCM 19710(T) (94.8%). The major cellular fatty acids (>10%) were found to be iso-C(18:1) ω9c, iso-C(15:0), Sum In Feature 3 (C(16:1) ω7c/C(16:1) ω6c), and C(16:0). The major ubiquinone was identified as Q-8 and the major cellular polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and unidentified phospholipids. The genomic DNA G+C content was determined to be 72.3 mol%. The results of the phylogenetic, genetic, phenotypic and chemotaxonomic analyses suggest that strain YN2-31A(T) represents a novel species of the genus Arenimonas, for which the name Arenimonas taoyuanensis sp. nov. is proposed. The type strain is YN2-31A(T) (=DSM 26777(T) = CCTCC AB2012964(T)).
