Abstract: | A Bacillus-like isolate, strain FJAT-13831T, isolated from the No. 1 pit soil of Emperor Qin’s Terra-cotta Warriors in Xi’an City, China, was studied to determine its taxonomic status. Dominant fatty acids of this organism included iso-C15:0, iso-C17:0, C16:0, iso-C13:0, anteiso-C15:0, and iso-C17:1ω5c. Comparative 16S rRNA gene sequence analysis confirmed the affiliation of this isolate to the genus Bacillus and indicated that it was closely related to Bacillus pseudomycoides DSM 12442T (99.72 % similarity). A phylogenetic analysis of the gyrB gene sequence similarities exhibited independent clustering of the isolate FJAT-13831T and showed 93.8 % (<95 %) sequence similarity with its closest phylogenetic neighbour B. pseudomycoides DSM 12442T. Separate standing of the strain FJAT-13831T was supported by a whole genome-based phylogenetic analysis with an average nucleotide identity value of 91.47 (<95 %) between isolate FJAT-13831T and B. pseudomycoides DSM 12442T and was consistent with the results of DNA–DNA hybridization (69.1 % relatedness). These findings support the conclusion that the isolate FJAT-13831T represents a novel species, for which the name Bacillus bingmayongensis sp. nov. is proposed. The type strain is FJAT-13831T (= CGMCC 1.12043T = DSM 25427T). |
