Characterization and Potential Applications of a Selenium Nanoparticle Producing and Nitrate Reducing Bacterium Bacillus oryziterrae sp. nov.

ABSTRACT: A novel nitrate- and selenite reducing bacterium strain ZYK^T was isolated from a rice paddy soil in Dehong, Yunnan, China. Strain ZYK^T is a facultative anaerobe and grows in up to 150, 000 ppm O₂. The comparative genomics analysis of strain ZYK^T implies that it shares more orthologues with B. subtilis subsp. subtilis NCIB 3610^T (ANIm values, 85.4-86.7%) than with B. azotoformans NBRC 15712^T (ANIm values, 84.4-84.7%), although B. azotoformans NBRC 15712^T (96.3% 16S rRNA gene sequence similarity) is the closest Bacillus species according to 16S rRNA gene comparison. The major cellular fatty acids of strain ZYK^T were iso-C_14:0 (17.8%), iso-C_15:0 (17.8%), and C_16:0 (32.0%).
