Bioremediation may be a branch of biotechnology that employs the utilization of living organisms, like microbes and bacteria, within the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation could also be wont to pack up contaminated groundwater or environmental problems, like oil spills.


Bioremediation relies on stimulating the expansion of certain microbes that utilize contaminants like oil, solvents, and pesticides for sources of food and energy. These microbes convert contaminants into small amounts of water, also as harmless gases like CO2.

Bioremediation requires a mixture of the proper temperature, nutrients, and foods. The absence of those elements may prolong the clean-up of contaminants. Conditions that are unfavourable for bioremediation could also be improved by adding “amendments” to the environment, like molasses, oil, or simple air. These amendments optimize conditions for microbes to flourish, thereby accelerating the completion of the bioremediation process.

Bioremediation can either be done "in situ", which is at the location of the contamination itself, or "ex situ," which may be a location far away from the location. Ex situ bioremediation could also be necessary if the climate is just too cold to sustain microbe activity, or if the soil is just too dense for nutrients to distribute evenly. Ex situ bioremediation may require excavating and cleaning the soil above ground, which can add significant costs to the method
