This is a controlled or spontaneous process that uses biodegradable or microorganism catalysis to degrade organic pollutants to restore polluted environment or remove pollutants from the environment. Microbial remediation technology is the use of microorganisms, indigenous bacteria, foreign bacteria, genetically engineered bacteria to transform and degrade the pollutants. It is mainly used for degradation of organic pollutants in soil. By changing various environmental conditions, such as nutrition, redox potential and co metabolism substrate, microbial degradation is enhanced to achieve the purpose of administration.
