Proposal of <i>Bacillus altaicus</i> sp. nov. Isolated from Soil in the Altai Region, Russia.

ABSTRACT: The Altai Republic remains a geographic region with an uncovered microbial diversity hiding yet undescribed potential species. Here, we describe the strain al37.1^T from the Altai soil. It showed genomic similarity with the Bacillus mycoides strain DSM 2048^T. However, the in silico DNA-DNA hybridization (DDH) was 61.6%, which satisfies the accepted threshold for delineating species. The isolate formed circular, smooth colonies, in contrast to the rhizoidal morphology typical of B. mycoides. The strain showed optimal growth under the following conditions: pH 6.5, NaCl concentration 0.5% w/v, and +30 °C. The major fraction of fatty acids was composed of C_16:0 (34.77%), C_18:1 (15.20%), C_14:0 (9.06%), and C₁
