/ˌbaɪoʊrəmidiˈeɪʃən/ (say .buyohruhmeedee'ayshuhn)

a process that uses microorganisms, enzymes, fungi, green plants, etc., to decontaminate the environment.
Bioremediation occurs when contaminated industrial sites and waterways are cleaned up by living organisms such as plants, fungi or microorganisms or their enzymes. Some microorganisms can be used to attack specific contaminants as in the use of bacteria to break down chlorinated pesticides, others are stimulated by the supply of nutrients to consume toxins, such as petroleum products, diesel, gasoline, fuel oils, and many pesticides (including DDT).
In relation to the treatment of pesticide residue in Australia, the CSIRO cautions that in order for bioremediation to be effective, conditions of soil aeration and nutrient levels must suit the microorganisms being used. If conditions are not right, the bacteria will reproduce slowly and the pesticide breakdown rate will be slow.
Bioremediation does not have as big a profile in Australia as it does in the US and in Europe.
