Summary
IGT has developed a microbial culture of Rhodococcus rhodochrous, designated as IGTS8, that is capable of specifically cleaving carbon-sulfur bonds in a range of organosulfur model compounds and is capable of removing organic sulfur from coal and petroleum without sacrificing the calorific value of the fuel. Although IGTS8 possesses the ability to specifically remove organic sulfur from coal, a major research need is to develop improved strains of microorganisms that possess higher levels of desulfurization activity and therefore will permit more favorable biodesulfurization process conditions: faster rates, more complete removal, and smaller reactor size. Strain improvement is the single most important aspect to the development of a practical coal desulfurization process and accordingly is the focus of research in this project. During the current quarter improved cloning vectors have been constructed and genomic libraries have been constructed and screened both in Escherichia coli and in Rhodococcus rhodochrous. Desulfurization genes have not yet been identified; however, the construction of additional genomic libraries and the implementation of new strategies for the detection of desulfurization genes are currently in progress.
