The main objective of this research was to investigate microorganisms capable of fossil fuel flue gas desulfurization and denitrification. The study used municipal sewage sludge as a carbon and energy source for SO{sub 2}-reducing cultures. The individual tasks developed a consortium of sulfate-reducing bacteria, investigated the design parameters for a continuous process, preformed a cost analysis, and screened sulfate-reducing bacteria. In the investigation of microbial reduction of NO{sub x} to nitrogen, tasks included screening denitrifying bacteria for NO and NO{sub 2} activity, developing optimum NO-reducing cultures, and investigating design parameters for a continuous system. This final report reviews the work previous to the current project, describes project objectives and the specific work plan, and reports results from the work completed during the previous reporting periods.
