Abstract

In recent years, the research and application of biocharsBCsin the remediation of contaminated soil have been a strong and widespread focus. It has been demonstrated to have remarkable impacts on the remediation of heavy metal and organic contamination in soil. BCs can improve soil properties, influence soil microbial communities, and achieve biochar mediated microbial remediation of contaminated soil. This review systematically analyzed the positive effects of BCs on microorganisms, including providing additional living environments, nutrients and improving native habitats including soil aggregates, pH, cation exchange capacityCECand enzyme activity. This led to changes in microbial abundance, activity, and community structure. However, it was important not to neglect the potential risks that BCs might have on the microbial community from that toxic substances carried, such as polycyclic aromatic hydrocarbonsPAHsand furan. Persistent free radicalsPFRsproduced by BCs during high temperature pyrolysis were also likely to be toxic to microorganisms. Moreover, the applications of biochar-mediated microbial remediation in contaminated soil were also discussed and reviewed. The review was concluded with an outlook on the direction of biochar microbial interactions in contaminated soil remediation, which can help us to select and modify BCs and integrate them more effectively with microorganisms in line with the target applications.
