| titleOfInvention | Method for dissolving medium and low-grade phosphate ore by immobilizing phosphate-dissolving bacteria with Fe3O4 magnetic nanoparticles |
| abstract | The invention relates to a method for dissolving medium and low-grade phosphate ore by using Fe3O4 magnetic nanoparticles to immobilize phosphate - dissolving bacteria. Firstly, magnetic nano-Fe 3 O 4 particles were prepared by solvothermal method; then qualified phosphate-dissolving bacteria were obtained through steps of separation, enrichment, and screening using soil as raw material; then the activated phosphate-dissolving bacteria and magnetic nano-Fe 3 O The four particles are respectively made into suspensions, and the two are mixed to achieve immobilization; finally, the immobilized phosphate-dissolving bacteria are inoculated into a medium containing medium and low-grade phosphate rock powder for cultivation. The present invention utilizes the good biocompatibility of Fe 3 O 4 , is easy to combine with bacterial strain cell surface groups, and can enhance the surface activity of bacterial strains. The phosphorus effect has been increased by 30%-60%, and it can better handle low- and medium-grade phosphate rocks. It has the advantages of simple operation, environmental friendliness, and good economic benefits. |
