Whey disposal has become a serious environmental problem and loss of revenue to the cheese industry. The U.S. Dept. of Energy has indicated that cheese whey has one of the lowest net feedstock costs per gallon of ethanol. The manufacture of ethanol is accomplished by specially selected yeast fermentation of lactose via the glycolytic pathway. Three commercial processes are described, the Milbrew process which produces single cell protein and alcohol, and the Carbery and Denmark processes which produce potable alcohol. Selected strains of Kluveromyces fragilis are used in all processes and in the latter process, effluents are treated under anaerobic conditions to produce methane, which replaces 17-20% of the fuel oil required by the distillation plant.
