METHOD FOR OBTAINING POLYHYDROXYALKANOATES FROM BEER-INDUSTRY WASTEWATER

摘要

The invention relates to a method for obtaining polyhydroxyalkanoates from beer-industry wastewater. The method for obtaining polyhydroxyalkanoates comprises three steps: acidogenic fermentation of the residual effluent from a beer industry in a reactor in order to obtain volatile fatty acids; feeding the fermented effluent obtained in the preceding step into a reactor that contains a mixed culture of microorganisms in order to select a biomass having high capacity for accumulation of polyhydroxyalkanoates; and discontinuously, through the addition of consecutive pulses, feeding the fermented effluent obtained in the first step into a reactor that contains the biomass selected in the second step.
