GROWTH-ASSOCIATED PRODUCTION OF POLY-BETA-HYDROXYBUTYRATE FROM GLUCOSE OR ALCOHOLIC DISTILLERY WASTE-WATER BY ACTINOBACILLUS SP EL-9

The characteristics of poly-beta-hydroxybutyrate (PHB) production from glucose or alcoholic distillery wastewater by isolated Actinobacillus sp. EL-9 were investigated. PHB production was not dependent on nutri ents limitation in Actinobacillus sp. EL-9. The PHB accumulation of Ac tibobacillus sp. EL-9 followed a growth-associated type where the cell growth and PHB accumulation were carried out simultaneously. The Acti nobacillus sp. EL-9 was shown to synthesize and accumulate PHB from al coholic distillery wastewater during growth, The best growth and PHB p roduction were obtained with enzyme-hydrolyzed alcoholic distillery wa stewater.
