Solubilization of K and P nutrients from coal gangue by <i>Bacillus velezensis</i>.

ABSTRACT: Accumulation of coal gangue (CG) poses significant risks to both human health and ecological systems, underscoring the urgent need for sustainable methods to utilize this abundant waste material effectively. In this study, we successfully screened and isolated the Bacillus velezensis bacterial strain to enhance the solubilization of potassium (K) and phosphorus (P) nutrients from CG. The study employed XRD, FTIR, SEM, and HPLC techniques to investigate the underlying mechanisms of CG solubilization. Various parameters such as CG particle size, incubation time, initial inoculation ratio, concentration of CG, pH, and temperature were optimized to maximize solubilization efficiency. The Bacillus velezensis bacterium can dissolve minerals of CG by adhering to its surface and secr
