SUMMARY OF RESEARCH DIRECTIONS

My laboratory has studied the methane-producing bacteria since I came to Georgia in 1982. In the last 25 years, our research has been funded by the National Science Foundation and the US Department of Energy, and we have published greater than 50 research papers and 20 reviews on these microorganisms. At one time or another, my laboratory has studied a wide range of topics concerning their nutrition, physiology, biochemistry, genetics and systematics. Currently, we are using methanogens to develop methods for biological H2 production, to selectively remove inhibitors from the cellulosic hydrolysates used in the ethanol fermentation, and to investigate it as a model organism for disease. As energy becomes more expensive, methanogens have great potential for biotechnological applications as well as waste treatment. In the biofuels arena, it has immediate application in the coproduction of methane with ethanol from biomass. In these processes, 20-30% of the energy from the biomass might actually be derived from methane.
