摘要：

A Gram-stain-negative, rod-shaped bacterium that formed yellow and viscous colonies was isolated from arsenic-contaminated soil of the Jianghan plain, Hubei Province, China, and it was designated 26-35(T). This strain was capable of resisting arsenate and arsenite with MICs of 40 and 20 mM, respectively. The 16S rRNA gene of the novel isolate displayed 96.7-94.2% sequence similarities to those of other known species of the genus Luteimonas. The respiratory quinone was ubiquinone-8 (Q-8). The DNA G+C content was 71.4 mol%. The predominant cellular fatty acids were iso-C-15:0, iso-C-16:0, iso-C-17:0, iso-C-11:0, iso-C-11:0 3-OH and iso-C-17:1 omega 9c. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic and physiological analysis indicated that the isolate represents a novel species of the genus Luteimonas, for which the name Luteimonas arsenica sp. nov. is proposed. The type strain is 26-35(T) (=KCTC 42824(T)=CCTCC AB 2014326(T)).
