These factors include the existence of a microbial population capable of degrading the pollutants, the availability of contaminants to the microbial population, the environment factors (type of soil, temperature, pH, the presence of oxygen and nutrients).

Then, what are the strategies for bioremediation?

Bioremediation of Oil Spills on Land Bioremediation strategies range from encouraging natural biodegradation processes (biostimulation), to supplementing the existing system with microorganisms able to degrade the contamination (bioaugmentation), to monitoring and verifying natural processes (natural attenuation).

Furthermore, what are the two types of bioremediation? There are two different types of bioremediation, in situ and ex situ.

Likewise, what types of microorganisms are used in bioremediation process?

Below are several specific bacteria species known to participate in bioremediation.

  • Pseudomonas putida.
  • Dechloromonas aromatica.
  • Deinococcus radiodurans.
  • Methylibium petroleiphilum.
  • Alcanivorax borkumensis.
  • Phanerochaete chrysosporium.

How effective is bioremediation?

Bioremediation has been most successful in cleaning up oil spills in the oceans. One of the important ways of cleaning up this oil spill was by using enhanced in-situ bioremediation techniques where fertilizers were added to provide nutrients to the microbes in cleaning up the oil spill by their metabolic action.

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 are the benefits of bioremediation?

Bioremediation has been successfully used to to clean up pollutants including crude oil, gasoline, pesticides, sewage, and chlorinated solvents used in cleaning supplies. The benefits of bioremediation include lower costs and less disruption of the contaminated environment when compared to other clean up methods.

What contaminants can be treated with bioremediation?

Contaminants treated using bioremediation include oil and other petroleum products, solvents, and pesticides. How Does It Work? Some types of microbes eat and digest contaminants, usually changing them into small amounts of water and harmless gases like carbon dioxide and ethene.

Who discovered bioremediation?

Bioremediation was first discovered around 600 BC by the Romans. Although their versions of the process aren't as developed as today's, they were still able to use it. They used bioremediation to clean their waste water. Much later, in the 1960's, bio-remediation was officially invented by George Robinson.

What is the role of bacteria in bioremediation?

The goal in bioremediation is to stimulate microorganisms with nutrients and other chemicals that will enable them to destroy the contaminants.

What is biodegradation process?

Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. Essentially, composting is an accelerated biodegradation process due to optimized circumstances.

What is insitu and Exsitu bioremediation?

In-Situ Bioremediation
-The treatment of contaminated soil or water in the site in which it was found. In-Situ Bioremediation of contaminated soil. The treatment of contaminated soil in the location where it was found can be considered more convenient compared to ex-situ bioremediation.

What is biostimulation used for?

Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation. This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g. in the form of molasses).

What is an example of bioremediation?

Some examples of bioremediation related technologies are phytoremediation, mycoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation.

What is bioremediation explain with examples?

Bioremediation in this sense involves the cleanup of blood and other bodily fluids that can pose health risks such as hepatitis, HIV, C. Diff and MRSA. Rather than using standard cleaning agents like bleach or ammonia, crime scene cleaners use enzyme cleaners to rid the scene of harmful substances.

Which would be an application of bioremediation?

Bioremediation has practical applications in cleaning up oil spills, storm water runoff, soil contamination, inland water pollution, and more. So even though you can't see them, we should be thankful that these microscopic organisms are taking on such an enormous job!

What is bioremediation in biology?

bioremediation. [ bī′ō-rĭ-mē′dē-ā′sh?n ] The use of biological agents, such as bacteria, fungi, or green plants, to remove or neutralize contaminants, as in polluted soil or water. Bacteria and fungi generally work by breaking down contaminants such as petroleum into less harmful substances.

How does microorganisms help in cleaning the environment?

The microorganisms decompose dead organic wastes of plants and animals converting them into simple substances. Thus, microorganisms can be used to degrade the harmful and smelly substances and thereby cleans up the environment.

When has bioremediation been used?

Bioremediation was used extensively to combat the devastating effects of the Exxon Valdez oil spill in 1989 and BP'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 is microbial remediation?

The use of microbes such as bacteria and fungi for soil rejuvenation is a form of environmental remediation. The objective of microbial remediation is to remove soil contaminants and pollutants. The microbial flora feeds on the contaminants, degrading them for energy and reproduction.

How bioremediation is helpful for purification of toxic metals?

Bioremediation is therefore an eco-friendly and efficient method of reclaiming environments contaminated with heavy metals by making use of the inherent biological mechanisms of microorganisms and plants to eradicate hazardous contaminants.

What is biodegradation and bioremediation?

Biodegradation basically involves the conversion of complex organic molecules to simpler (and mostly non-toxic) ones. Bioremediation refers to the process of using microorganisms to remove the environmental pollutants i.e. the toxic wastes found in soil, water, air etc.
