bioremediation

(bī′ō-rĭ-mē′dē-ā′shən)
n.
The use of biological agents, such as bacteria or plants, to remove or neutralize contaminants, as in polluted soil or water.

bioremediation

(1) The processing of industrial waste by genetically modified microorganisms to generate a less toxic end product.
(2) The use of plants, microorganisms and/or nutrients to supplement biodegradation—e.g., in pollution, oil spills; the release of organic chemicals to water and soil often carries long-term consequences to the integrity of an ecosystem; assessment of the extent of biotic remediation of soil contaminated by polyaromatic hydrocarbons (e.g., mineralisation of naphthalene and phenanthrene by bacteria) requires that abiotic attenuating processes—chemical dilution, migration, volatilisation and sorption—be considered in the model.

bioremediation

(bī″ō-rĕ-mē″dē-ā′shŭn)
The conversion of hazardous wastes and pollutants into harmless materials by microorganisms.

bioremediation

a process typically involving the use of organisms, generally MICROORGANISMS or PLANTS, to remove or detoxify pollutants, contaminants and other unwanted substances in the environment, including spilled oil, solvents and pesticides. However, bioremediation can occur by modifying the environment to improve biological processes, without the addition of organisms.
