Examples of bioremediation in the following topics:

  • Polycyclic Aromatic Hydrocarbons

    • Bioremediation is the use of micro-organism metabolism to remove pollutants.
    • Bioremediation can occur on its own (natural attenuation or intrinsic bioremediation) or can be spurred on via the addition of fertilizers to increase the bioavailability within the medium (biostimulation).
    • Microorganisms used to perform the function of bioremediation are known as bioremediators.
    • Not all contaminants, however, are easily treated by bioremediation using microorganisms.
    • Mycoremediation, is a form of bioremediation, the process of using fungi to degrade or sequester contaminants in the environment.
  • The Degradation of Synthetic Chemicals in Soils and Water

    • Microbes are used for bioremediation in situ of contaminated soil.
    • Microorganisms that can remove contaminants from the environment are called bioremediators.
  • Aerobic Hydrocarbon Oxidation

    • Understanding how microbes digest hydrocarbons has started the field of microbial biodegradation, a type of bioremediation.
    • Therefore, biosurfactant-producing microorganisms may play an important role in the accelerated bioremediation of hydrocarbon-contaminated sites.
  • Iron Oxidation

    • G. metallireducens) can use toxic hydrocarbons such as toluene as a carbon source, there is significant interest in using these organisms as bioremediation agents in ferric iron-rich contaminated aquifers .
    • While these processes may often be less significant ecologically, they are of considerable interest for bioremediation, especially when heavy metals or radionuclides are used as electron acceptors.
  • Betaproteobacteria

    • Nitrosomonas are useful in treatment of industrial and sewage waste and in the process of bioremediation.
  • Electron Donors and Acceptors in Anaerobic Respiration

    • Since some ferric iron-reducing bacteria (e.g.G. metallireducens) can use toxic hydrocarbons (e.g. toluene) as a carbon source, there is significant interest in using these organisms as bioremediation agents in ferric iron contaminated aquifers.
  • Microbes and Ecosystem Niches

    • In addition, microbial processes can be co-opted for biodegradation or bioremediation of domestic, agricultural, and industrial wastes, making the study of microbial ecology particularly important for biotechnological and environmental applications.
