Mineral-carbon-based microbial agent, its preparation, and its use in environmental remediation

Abstract

The present disclosure discloses a mineral- and carbon-based microbial agent, its preparation, and its use in environmental remediation. By comparing the DNA-SIP exploration results with the results of indoor culture and isolation experiments, a strain LJD-17 with BAP in-situ degradation function was isolated and identified from contaminated soil. The LJD-17 or various types of microbial agents prepared from the strain was separately inoculated into a medium with an initial BAP concentration of 20 mg / L. After culturing for 30 days, the degradation rates all reached above 40%, and the degradation rate of the prepared mineral-carbon-based microbial agent even reached 75.3%. Therefore, the strain has good application potential in the bioremediation of BAP.
