Influence of aerobic and anoxic microenvironments on polyhydroxyalkanoates (PHA) production from food waste and acidogenic effluents using aerobic consortia

► PHA production using un-fermented and fermented food waste. ► Among the microenvironments operated, anoxic condition showed higher PHA production. ► Produced PHA was composed of the copolymer PHB-co-PHV. ► Integrating approach of PHA production with fermentative H2 production. ► The use of food waste as substrate reduces the negative impact of pollution on the environment.
