A method for carrying out biochemical reaction is disclosed. The method includes placing a suitable substrate in a cavity formed in a subterranean formation, inoculating the substrate with a culture of microorganisms, maintaining conditions suitable for the growth of the microorganisms, allowing the microorganisms to grow in the substrate in the cavity, and recovering a biochemical product formed thereby. The method is especially suitable for the conversion of alkali-oxidized or hydrolyzed coal, such as lignite, to methane.
