Bacillus pasteurii and application thereof
The bacillus pasteurii is preserved in the China Center for Type Culture Collection, and the preservation number of the bacillus pasteurii is CCTCC M 20241864; the urealyticum mutant strain with high urease activity is successfully screened by adopting a normal-pressure and room-temperature plasma technology, and the capability of inducing precipitation of calcium carbonate can be remarkably enhanced, so that the mineralization efficiency of microorganism-induced calcium carbonate deposition and the sandy soil reinforcement effect are improved; in addition, an improved bacterium-mediated microorganism-induced mineralization reaction kinetic model is established, and an improved process and method for reinforcing sandy soil through strains are provided according to the requirement for efficient control of ammonium emission. The research result of the invention has important scientific significance and wide application prospect for improving the practical application effect of the microbial soil reinforcement technology and improving the environmental problem caused by the byproduct waste ammonium solution.
