Abstract: A nutrient composition for enhancing biogenic methane production from a carbonaceous material is described. The nutrient composition comprises a source of phosphorus (P) and a source of nitrogen (N), wherein the molar ratio of phosphorus to nitrogen (P/N) is greater than 1.5, and the nitrogen concentration is at least 0.1 m M and less than 1.7 m M. A process for enhancing biogenic methane production from a carbonaceous material is also described. The process involves contacting the nutrient composition of the invention with the carbonaceous material for a period of time to biogenically produce methane and subsequently collecting methane from the carbonaceous material. The process may further comprise contacting the carbonaceous material with a second nutrient composition, wherein the second nutrient composition has a P/N molar ratio greater than the P/N molar ratio of the former nutrient composition.
