Essay # 3 bioremediation: environmental hazards and risks that occur as a result of accumulated toxic chemicals or other waste and pollutants could be reduced or eliminated through the application of biotechnology in the form of bioremediation. Bioremediation uses microorganisms to degrade organic contaminants in soil, groundwater, sludge, and solids the microorganisms break down contaminants by using them as an energy source or cometabolizing them with an energy source. Soil contamination and bioremediation research paper by scribbler soil contamination and bioremediation an examination of the soil remediation of chemical spills together with bioremediation processes. Bioremediation has been used to treat a number of organic and inorganic contaminants in the environment including hydrocarbons, chlorinated chemicals, pesticides, metals, and other contaminants various treatment methods may be used depending on the chemicals of concern, but most generally employ microorganisms to reduce toxic potential.

(ryan & mayfield, 2012, p 330) bioremediation — the application of biological processes to address environmental problems — is among the technologies being touted to treat contaminated soils and water sources, and to process wastes. Bioremediation focuses on the former while it is recognized that at present biological treatment processes play a major role in preventing and reducing the organic and inorganic environmental contamination from the municipal, industrial and agricultural sectors.
The cleanup of contaminated soil human activity has introduced many toxic substances into the environment’s soil and groundwater according to an essay published by montana state university , “during bioremediation, microbes utilize chemical contaminants in the soil as an energy source and, through oxidation-reduction reactions, metabolize. Parallel to population increase in the world, soil and water resources are being polluted rapidly the importance of environmental biotechnology in pollution management is increasing.

Bioremediation is a technology that utilizes the metabolic potential of microorganisms to clean up contaminated environments one important characteristic of bioremediation is that it is carried out in non-sterile open environments that contain a variety of organisms of these, bacteria, such as. And recover contaminated soil the process of bioremediation uses various agents such as bacteria, fungi, algae and higher plants as major tools in treating heavy metals present in the environment. Ex-situ bioremediation occurs after contaminated soils are excavated it can be expensive, mostly due to the cost of excavation and transportation of the soil.

What is bioremediation bioremediation is the process of using organisms to neutralize or remove contamination from waste it is very important to understand that this form of waste remediation uses no toxic chemicals, although it may use an organism that can be harmful under certain circumstances. Contaminated soils can be treated in variety of ways to eliminate contaminates it is possible in principle to treat contaminated soils biologically in place by pumping oxygenated, nutrient-enriched water through the soil in a recirculating system.
