Silicate minerals enhance the expression of genes related to mineral dissolution by <i>Priestia aryabhattai</i> strain C4-10.

ABSTRACT: Silicate mineral-microbe interactions are essential for soil formation, element biogeochemical cycles, and carbon sequestration. However, the molecular mechanisms by which gram-positive bacteria mediate mineral dissolution remain largely unexplored. Here, we characterized a highly effective mineral-dissolving Priestia aryabhattai strain, C4-10, for its biotite and lizardite dissolution activity, alongside the underlying molecular mechanisms. In the medium supplemented with biotite or lizardite, C4-10 significantly increased the Fe, Mg, and Si concentrations between 4 and 48 h of incubation compared to the controls. Notably, in the C4-10-inoculated medium supplemented with biotite or lizardite, significantly decreased pH values in the medium and increased cell counts and biofilm form
