Role of Microorganisms for Removing Oil Pollution from Water

This study investigates the role of microorganisms in removing oil pollution from water. The fight against oil pollution since the emergence of this black and precious substance, has been part of scientific research which had been attracted the attention of experts. For nearly 50 years, microbiologists have been researching removal of heterocyclic compounds, including sulfur heteroatoms, from petroleum fractions. The first patent for this was in Zobel s research in the early 1950s. Research in this area continued until 1989, when the 4S pathway for the decomposition of sulfur compounds was identified by Dr. Kilbane at the I.G.T. It should be noted that in this pathway, the bacteria separate and release sulfur from the model compound, di benzothiophene in a completely specific manner without damaging the carbon skeleton. The final product of this reaction is mono hydro xybiphenyl which is dissolved in oil and organic cut, and as a result, while maintaining the calorific value of the fuel, the separation step is easier in the reactor.
