bioremediation

[‚bī·ō·ri‚mē·dē′ā·shən]
(ecology)
The use of a biological process (via plants or microorganisms) to clean up a polluted environmental area (such as an oil spill).

Bioremediation

A process that uses biological agents, such as bacteria, fungi, or green plants, to remove or neutralize contaminants, as in polluted soil or water. Plants can be used to aerate polluted soil and stimulate microbial action. The cleanup of a contaminated site using biological methods, i.e., bacteria, fungi, and plants, is a form of bioremediation. Organisms are used to either break down contaminants in soil or water, or accumulate the contaminants in their tissue for disposal. Many bioremediation techniques are substantially less costly than traditional remediation methods using heat, chemical, or mechanical means.
