Abstract

A facultatively anaerobic, selenate- and arsenate-reducing bacterium, designated strain SF-1T, was isolated from a selenium-contaminated sediment obtained from an effluent drain of a glass-manufacturing plant in Japan. The bacterium stained Gram-positive and was a motile, spore-forming rod capable of respiring with selenate, arsenate and nitrate as terminal electron acceptors. The major cellular fatty acids of the strain were iso-C15:0, iso-C17:ω10c and C16:1ω7c alcohol. The G + C content of the genomic DNA was 42.8 mol%. Though the nearest phylogenetic neighbour was Bacillus jeotgali JCM 10885T, with a 16S rRNA gene sequence similarity of 99.6%, DNA-DNA hybridization studies showed only 14% relatedness between these strains, a level that is clearly below the value recommended to delimit different species. This, together with the phenotypic differences (utilization of electron acceptors, NaCl tolerance), suggests that strain SF-1T represents a novel species of the genus Bacillus, for which the name Bacillus selenatarsenatis sp. nov. is proposed. The type strain is SF-1T (=JCM 14380T =DSM 18680T).
