- Abstract
With the development of modern agriculture, the pollution caused by the use of chemical fertilizers and pesticides has become a serious problem, posing a threat to human health and the living environment. Bioremediation technology is receiving more and more attention due to the safety of contaminated soil, non-secondary pollution, and low cost. In this study, white rot fungi were immobilized by the adsorption method, and the functional plants suitable for reducing carbofuran were screened by pot experiment. Based on a previous study, a combined remediation technique was established. The results showed that after 30 days, compared to the single bioremediation of carbofuran-contaminated soil, the degradation rate increased by 19% through the corn-white rot fungi combined remediation, and by 17% using the sorghum-white rot fungi combined remediation. The effect of the pesticide content in soil on the combined remediation is mainly reflected in the significant difference in the number of microorganisms (p < 0.05). Combined bioremediation may be a better alternative to mitigate the impact of high pollution on microorganisms at different pollutant concentrations compared to single microbial bioremediation or phytoremediation.
