Anaerobic Toluene Oxidation in the Metabolism of the Fe(III)-Reducing Microorganism GS-15




This is a potential pathway for the oxidation of toluene in Fe(III)-reducing microorganisms, which play important roles in sediments naturally composed of hydrocarbons. The oxidation of toluene, an aromatic hydrocarbon, in these microorganisms is coupled to Fe(III) reduction. GS-15 is the first microorganism discovered to link aromatic compound oxidation to the reduction of Fe(III). The oxidation of p-cresol and phenol in these organisms is also coupled to Fe(III) reduction. Under strict anaerobic conditions in these organisms, GS-15 can completely oxidize toluene to carbon dioxide by utilizing Fe(III) as the only electron acceptor in the reaction.
This mechanism can be used to clean up toxic oil spills or other toluene contaminations by introducing the microorganisms to the site.

Here is the link to the CiteULike article discussing these anaerobic metabolic processes.

  • 1) This is an excellent example of a potentially useful application of oxidation to decontaminate the environment.
    2) You need to put the reagents on the arrows. In this case the "reagent" is the organism GS-15 and Fe3+
    3) Your citeulike reference is incomplete (no author, etc.)
    4) At least your last sentence is lifted word for word from the article. This is unacceptable. Rewrite your thoughts in your own words as simply as you can.

  • In the last sentence you are trying to explain why this research is important. Delete that sentence. Do not look at the article and write why YOU think this is important in your own simple words.
