Abstract
Coal is treated aerobically or anaerobically to produce humic acid, volatile fatty acids, lower alcohols, and/or methane using a consortium of bacteria designated Mic-1 or KSARC56. This process can also be used to convert aromatic compounds, such as phenols and derivatives thereof, to methane and carbon dioxide.
