What is the process of bioremediation?
Bioremediation is a process that uses mainly microorganisms, plants, or microbial or plant enzymes to detoxify contaminants in the soil and other environments.
From: Microbial Biodegradation and Bioremediation, 2014..
How long has bioremediation been used?
In fact, however, bioremediation is not new. It has been used commercially for more than 20 years. The first commercial in situ bioremediation system was installed in 1972 to cleanup a Sun Oil pipeline spill in Ambler, Pennsylvania.
What are the disadvantages of bioremediation?
Disadvantages of bioremediation include (Sharma & Reddy, 2004): 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.
What is bioremediation give an example?
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.
Why bioremediation is required?
Bioremediation technology makes it possible to clean up the oceans after major oil spills and other unfortunate environmental disasters. By using naturally occurring bacteria to eliminate contaminants in the sea, we protect and encourage aqua-culturists and their attempts to solve the problem of global food production.
What is called bioremediation?
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments.
How do humans use plants for bioremediation?
Plants use solar energy (through photosynthesis) to extract chemicals from the soil and to deposit them in the above-ground part of their bodies, or to convert them to a less toxic form. These plants can then be harvested and treated, removing the pollutants.
How safe is bioremediation?
Bioremediation is very safe because it uses the same microbes that already naturally occur in soil or water. This process simply adds more of these organisms to those already present. No dangerous chemicals are used in the process and harmful contaminants are completely destroyed.
How well does bioremediation work?
Bioremediation provides a good cleanup strategy for some types of pollution, but as you might expect, it will not work for all. … Depending on the site and its contaminants, bioremediation may be safer and less expensive than alternative solutions such as incineration or landfilling of the contaminated materials.
How long is soil remediation?
one to two daysMost remediations can be completed in one to two days but large scale contamination of soil and/or groundwater will take longer.
What organisms are used in bioremediation?
Microorganisms can also survive in contaminated habitats because they are metabolically able to exploit contaminants as potential energy sources . In bioremediation, microorganisms with biological activity, including algae, bacteria, fungi, and yeast, can be used in their naturally occurring forms.
What are 2 types of bioremediation?
What are the Different Types of Bioremediation?Microbial bioremediation uses microorganisms to break down contaminants by using them as a food source.Phytoremediation uses plants to bind, extract, and clean up pollutants such as pesticides, petroleum hydrocarbons, metals, and chlorinated solvents.More items…
