A Gram-positive bacterium, designated strain CW 7T, was isolated from forest soil in Anhui Province, south-east China. Cells were strictly aerobic, motile with peritrichous flagella and rod-shaped. The strain grew optimally at 30–37 °C and pH 7.0–8.0. The major fatty acids of strain CW 7T were anteiso-C15 : 0, iso-C15 : 0 and anteiso-C17 : 0. The predominant menaquinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The G+C content of the genomic DNA was 42.3 mol%. Phylogenetic analysis indicated that strain CW 7T belonged to a monophyletic cluster within the genus Bacillus and showed 16S rRNA gene sequence similarities of less than 96.5 % to recognized species of the genus Bacillus. The results of the polyphasic taxonomic study, including phenotypic, chemotaxonomic and phylogenetic analyses, showed that strain CW 7T represents a novel species of the genus Bacillus, for which the name Bacillus pallidus sp. nov. is proposed. The type strain is CW 7T (=KCTC 13200T=CCTCC AB 207188T=LMG 24451T).

A maximum-parsimony phylogenetic tree based on 16S rRNA gene sequences, showing the position of strain CW 7T, and a two-dimensional thin-layer chromatograph of a polar lipid extract of strain CW 7T are available as supplementary material with the online version of this paper.
