Processing of coal with microorganisms. Final report
A computer-assisted survey and evaluation of the international literature on microbial transformations of coal and relevant organic compounds was performed to identify candidate microorganisms and biological processes potentially applicable to coal bioprocessing. The vast majority of the literature on coal bioprocessing deals with desulfurization via pyrite removal, and some bioprocessing schemes have been proposed. Reports on organic sulfur and metals removal from coal have recently appeared. As yet unevaluated are systems for removal of other elements from coal such as oxygen and nitrogen. However, model substrates resembling certain important O and N functional groups in coal are degraded by microorganisms. These microorganisms could potentially be useful in coal bioprocessing. Our laboratory results suggest that a strain of Bacillus, capable of vanillic acid decarboxylation, may remove carboxyl groups from coal. We were not able to confirm literature reports on organic S removal from coal by Sulfolobus, or on coal liquefaction by certain fungi. 90 refs., 4 figs., 3 tabs.
