Bioremediation is an environmental science that amplifies natural biological actions to remedy or remediate polluted groundwater and contaminated soil. Rather than using expensive environmental remediation equipment to remove untreated toxic materials and dispose of them elsewhere, bioremediation techniques use biological microbes to do the cleanup work.

2020-12-22 · Bioremediation is a technology with many advantages over traditional methods of pollution control. These include reduced cost compared to more traditional methods and sustainability.

the use of prokaryotes as natural  Bioremediation refers to a set of processes which involve the use of living things to break down hazardous substances in the environment into less toxic or  ​The basic premise of bioremediation is to accelerate microbial activity using nutrients (carbon, phosphorus, nitrogen, etc.) to create conditions conducive to  Rhizoremediation, which is the most evolved process of bioremediation, involves the removal of specific contaminants from waste product of contaminated sites  Laboratory tests for evaluation of treatment of highly contaminated sediment.

· Geobacter sufurreducens bacteria can turn uranium dissolved in groundwater into a non-soluble, collectable form. Activity include addition of amend­ments such as nutrients or oxygen while passive remediation utilizes natural attenuation to ad­equately characterize, model and monitor the site to record natural attenuation and protection of potential receptors. Classification of Bioremediation Technology: Title: A Citizen's Guide to Bioremediation Author: U.S. EPA, Office of Solid Waste and Emergency Response Subject: The Citizens' Guides are 2-page fact sheets that explain, in basic terms, the operation and application of the most frequently used innovative treatment technologies. Ex situ bioremediation includes elimination of waste materials and their collection from the contaminated site or place to assists microbial degradation. Ex situ bioremediation technology includes most of demerits and limitations as it is expensive process due to costs associated with solid handling process, such as excavation, screening and fractionation, mixing, homogenising and final disposal.

Bioremediation also has the potential to clean-up polluted air, soil and water: waste, stripping of contaminated soil, cleaning up of pollution including oil spills, 

These specific microbes consume and break down the pollutants when they are introduced to a contaminated site. Methods of bioremediation may utilize bacteria, fungi or even plants, depending upon the region of Bioremediation is an ecologically viable technique that aids in cleanup of contaminated site by using natural biological (microbes) activity. It is a relatively low-cost, low-technology technique and can often be carried out on site. Se hela listan på eartheclipse.com Bioremediation relies on stimulating the growth of certain microbes that use contaminants like oil, solvents, and pesticides as a source of food and energy. These microbes consume the contaminants, converting them into small amounts of water and harmless gases like carbon dioxide.
