ABSTRACT:
Methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content are described. The methods may include accessing a consortium of microorganisms in a geologic formation that includes a carbonaceous material. They may also include providing a phosphorous compound to the microorganisms. The phosphorous compound stimulates the consortium to metabolize the carbonaceous material into a metabolic product with enhanced hydrogen content. Also, methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content by providing a yeast extract amendment to a consortium of microorganisms is described. The yeast extract amendment stimulates the consortium to metabolize carbonaceous material in the formation into the metabolic product with enhanced hydrogen content.
