Bioremediation of cyanide-contaminated soils:A review

The current research development in degradation mechanism,degradation path and affecting factors of cyanide-contaminated soil bioremediation techniques including phytoremediation,microbial remediation and combined bioremediation are reviewed,and their research trend and application prospect are discussed. The focus areas for further research are pointed out,such as:integration of multiple remediation techniques aiming at remediation efficiency increase and according to combined contaminated soil type,microbial immobilization and fungus-root association for improving of stress tolerance and degradation efficiency of microorganism,and in-situ test aiming at engineering application,which provide some new ideas concerning comprehensive treatment and remediation of cyanide-contaminated soils.
