Contaminants treated using bioremediation include oil and other petroleum products, solvents, and pesticides .
What metals can be treated by bioremediation?

Where else could you use bioremediation?
- Crime scene cleanup. Bioremediation in this sense involves the cleanup of blood and bodily fluids that can pose health risks such as hepatitis, HIV, and MRSA. ...
- The cleanup of contaminated soil. ...
- Oil spill cleanup.
Is bioremediation safe for the environment?
Bioremediation is a safe, natural process that produces no harmful by-products. Since it can be done onsite, it is often more cost effective than having soil or water hauled away for burning or other reclamation. It is also safer for workers because no harmful chemicals are used in the process.
Which environmental pollutants is mainly removed through bioremediation process?
The pollutant removal process depends mainly on the pollutant nature, which includes pesticides , agrochemicals, chlorinated compounds, heavy metals, xenobiotic compounds, organic halogens, greenhouse gases, hydrocarbons, nuclear waste, dyes plastics and sludge.
Why is bioremediation bad?
Disadvantages of Bioremediation
If the process is not controlled it is possible the organic contaminants may not be broken down fully resulting in toxic by-products that could be more mobile than the initial contamination. ... If an ex-situ process is used, controlling volatile organic compounds (VOCs) may be difficult.
What are two examples of bioremediation?
Bioremediation companies that specialize in soil and groundwater use microbes that feed on the hazardous substances for energy, which results in the breakdown of the targeted contaminant. Examples include junkyards, industrial spills, land development, fertilizer use, and more .
What are the types of bioremediation?
- 1) Biostimulation. As the name suggests, the bacteria is stimulated to initiate the process. ...
- 2) Bioaugmentation. At times, there are certain sites where microorganisms are required to extract the contaminants. ...
- 3) Intrinsic Bioremediation. ...
- Incineration. ...
- Phytoremediation.
Which micro organisms are used in bioremediation?
- Pseudomonas putida.
- Dechloromonas aromatica.
- Deinococcus radiodurans.
- Methylibium petroleiphilum.
- Alcanivorax borkumensis.
- Phanerochaete chrysosporium.
What is the process called in which organisms are used to remove contaminants from the environment?
Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminants in the soil and other environments.
How does bioremediation affect us?
Bioremediation is the use of microbes to clean up contaminated soil and groundwater . Microbes are very small organisms, such as bacteria, that live naturally in the environment. Bioremediation stimulates the growth of certain microbes that use contaminants as a source of food and energy.
When has bioremediation been used?
Bioremediation was used extensively to combat the devastating effects of the Exxon Valdez oil spill in 1989 and British Petroleum’s Deepwater Horizon oil spill in 2010 . In both oil spills, microorganisms were used to consume petroleum hydrocarbons and played a significant role in reducing the environmental impact.
What are the important facts on bioremediation?
The bioremediation process creates relatively few harmful byproducts (mainly due to the fact that contaminants and pollutants are converted into water and harmless gases like carbon dioxide). Finally, bioremediation is cheaper than most cleanup methods because it does not require substantial equipment or labor.
What is an example of bioremediation?
Biological treatment, bioremediation, is a similar approach used to treat wastes including wastewater, industrial waste and solid waste. ... Some examples of bioremediation related technologies are phytoremediation, bioventing, bioattenuation, biosparging, composting (biopiles and windrows) , and landfarming.
What is bioremediation and its advantages?
The major benefits of bioremediation are: Completely natural process with almost no harmful side effects . Carried out in situ for most applications with no dangerous transport . Quick turnaround time to make soil and water useful . Minimal equipment needed except for specialized pieces.
How do humans use plants for bioremediation?
Specific enzymes such as nitroreductases and dehalogenases are used by plants to degrade organic contaminants [132]. These enzymes must be used at optimal conditions of temperature and pH for efficient degradation of contaminants.
