Abstract
This paper describes the microbial production of polyhydroxyalkanoates (PHAs) from food industry wastes by a mixed culture of activated sludge microorganisms. The physical and chemical properties of the bioplastics produced by the microorganisms from malt and soy wastes were different. The melting points of the products were compared, and the co-polymer composition of the products was investigated by gas chromatography and nuclear magnetic resonance spectroscopy. In using activated sludge to convert the carbon source into PHAs, not only are environment-friendly bioplastics produced, but also the problem of disposing of municipal activated sludge is partly solved. The selection of food industry waste as the carbon source can also reduce the cost of producing PHAs.
