Claim Text:
1. A method for producing ethanol from biomass from digestion by microorganisms, which comprises steps of: a) adding exogenous hydrogen gas into a fermentation container containing biomass; b) adding ethanol to the fermentation container to stimulate production of ethanol from the digestion of the biomass; c) digesting the biomass in the fermentation container with at least one microorganism which produces ethanol from digestion of cellulose, hemi-cellulose, starch, lignin or lignocellulosic substrates or mixtures thereof contained in the biomass at a temperature of about 50° C. or less; and d) reducing partial pressures of carbon dioxide and hydrogen gases produced by the digesting, thereby causing a ratio of reactants and products to shift to a new thermodynamic equilibrium that yields a greater concentration of the ethanol from the digested biomass; and e) collecting the ethanol produced from the digested biomass.
