Research progress on microbial remediation technology and mechanism of oil-contaminated soil
Microbial remediation has been widely studied due to its low cost,low environmental impact and high efficiency.The research hotspots for microbial remediation are the selection of petroleum-degrad-ing microorganisms and the removal effect of multiple microbial complex bacteria on petroleum compo-nents,but there are relatively few practical applications and mechanism studies on microbial technology.This article sorts out various technical means and practical application research of microbial remediation of oil-contaminated soil,reports the mechanism of microbial remediation of petroleum pollutants,and puts forward the future research and development direction of microbial remediation.
