ABSTRACT:
A method for stimulating methane production from a carbonaceous material is described. The methods may include the step of contacting the material with cells of a methanogenic consortium under anaerobic conditions to form a reaction mixture. The method may also include maintaining anaerobic conditions for a time sufficient to permit methanogenesis, and collecting methane from anaerobic water or head space of the reaction mixture.
