Abstract (EN): A Gram-positive, aerobic, non-motile, endospore-forming rod, designated DS22(T), was isolated from a drinking-water treatment plant. Cells were catalase- and oxidase-positive. Growth occurred at 15-37 degrees C, at pH 7-10 and with <8% (w/v) NaCl (optimum growth: 30 degrees C, pH 7-8 and 1-3% NaCl). The major respiratory quinone was menaquinone 7, the G + C content of the genomic DNA was 36.5 mol% and the cell wall contained meso-diaminopimelic acid. On the basis of 16S rRNA gene sequence analysis, strain DS22(T) was a member of the genus Bacillus. Its closest phylogenetic neighbours were Bacillus horneckiae NRRL B-59162(T) (98.5% 16S rRNA gene sequence similarity), Bacillus oceanisediminis H2(T) (97.9%), Bacillus infantis SMC 4352-1(T) (97.4%), Bacillus firmus IAM 12464(T) (96.8%) and Bacillus muralis LMG 20238(T) (96.8%). DNA-DNA hybridization, and biochemical and physiological characterization allowed the differentiation of strain DS22(T) from its closest phylogenetic neighbours. The data supports the proposal of a novel species, Bacillus purgationiresistans sp. nov.; the type strain is DS22(T) (=DSM 23494(T)=NRRL B-59432(T)=LMG 25783(T)).
