title: Luteimonas arsenica sp. nov., an arsenic-tolerant bacterium isolated from arsenic-contaminated soil.
abstract: 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 26-35T. 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-C15 : 0, iso-C16 : 0, iso-C17 : 0, iso-C11 : 0, iso-C11 : 0 3-OH and iso-C17 : 1ω9c. 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 26-35T (=KCTC 42824T=CCTCC AB 2014326T).
