Biomethanation of coal is a phenomenon carried out in concert by a mixed population (consortium) of at least three different groups of anaerobic bacteria and can be considered analogous to that of anaerobic digestion of municipal waste. The exception, however, is that unlike municipal waste; coal is a much complex and difficult substrate to degrade. This project was focused on studying the types of microorganisms involved in coal degradation, rates of methane production, developing a cost-effective synthetic culture medium for these microbial consortia and determining the rate of methane production in bench scale bioreactors.
