摘要： A novel aerobic, non-spore-forming, non-motile, catalase- and oxidase-positive, Gram-stain-negative, coccoid to short-rod-shaped bacterial strain, designated YW11(T), was isolated from soil under long-term application of triazophos. The strain was able to hydrolyse triazophos. Strain YW11(T) grew at 15-40 degrees C (optimum at 28 degrees C), at pH 5.0-8.0 (optimum at pH 7.5) and with 0-5.0 % (w/v) NaCl (optimum at 0.5 %). The major respiratory quinone was ubiquinone 10 (Q-10) and the major cellular fatty acids were C-18:1 omega 7c, C-16:0, C-18:1 2-OH and C-18:0. The genomic DNA G+C content of strain YW11T was 69.6 +/- 0.5 mol%. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, an unknown glycolipid and two unknown aminolipids. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain YW11(T) was a member of the genus Roseomonas, and showed the highest sequence similarity to Roseomonas cervicalis KACC 11686(T) (97.9 %) and Roseomonas aestuaril KACC 19645(T) (97.8%) and then to Roseomonas ludipueritiae KACC 138431 (96.9%). Strain YW11(T). showed low DNA DNA relatedness with R. cervicalis KACC 116861 (32.3 2.9%), R. aestuarii KACC 16549(T) (28.2 2.6%) and R. ludipueritiae KACC 138431 (30.2 2.6 %). Based on the results of phylogenetic analysis and DNA DNA hybridization, the whole-cell fatty acid composition as well as biochemical characteristics, strain YW11(T) was clearly distinguished from all recognized species of the genus Roseomonas and should be assigned to a novel species of the genus Roseomonas, for which the name Roseomonas rhizosphaerae sp. nov. is proposed. The type strain is YVV11(T) (=KACC 17225(T)=CCTCC AB2013041(T)).
