Microbial Remediation of Polycyclic Aromatic Hydrocarbons Contaminated Soil:A Review
摘要
Abstract
Polycyclic aromatic hydrocarbons (PAHs), which mainly resulted from incomplete combustion of coal, petroleum and other fuels, are a kind of carcinogenic, teratogenic and mutagenic persistent organic pollutants (POPs). Each of them has stable chemical structure and easily adsorb on solid surface and organic humus. For this case, PAHs can exist in the natural environment for a long time and has great potential harm to human health and ecological environment. In China, the PAHs pollution in soil is a very serious problem, so it is urgent to explore an effective technology for removal of PAHs. Recently, microbial remediation was focused on for its advantages of low cost, high efficiency and less pollution with PAHs-degrading bacteria and fungi. The enzymes are im-portant in degradation of soil PAHs during microbial remediation. PAHs can be degraded through the oxidation of benzene ring by dioxygenase enzymes of bacteria. PAHs can also be oxidized by lignin degrading enzymes or monooxygenases of fungi. The stabili-ties of intermediates are usually lower than those of parent PAHs and can be easily further degraded. Thus, the microbial remediation has been utilized in the treatment practice of soil PAHs. In this work, the PAHs-degrading microbe and mechanism were reviewed. The influences of different factors on the microbial remediation of soil PAHs were discussed. Three microbial remediation techniques of PAHs-contaminated soil were introduced. Moreover, some suggestions were provided for the development of the microbial reme-diation technology to remove PAHs in soil.关键词
