Alcoholic distillery wastes are utilized as dual purposes to produce PHB in lower production cost and to reduce the amount of waste to be treated. In this study, various attempts were made to increase PHB production under various conditions by Actinobacillus sp. EL-9 in a shaker culture. The addition of glucose, NH$_{4}$NO$_{3}$ to alcoholic distillery wastes slightly promoted cell mass and PHB production. Enzyme hydrolysis of alcoholic distillery wastes increased the production of PHB than that of untreated waste and acid hydrolysis treatment. The PHB weight in alcoholic distillery wastes was 1.91 g/l. Fermentation process of PHB production reduced the amount of COD value up to 54%, which reduced organic loading rate and capacity of activated sludge system.
