Yeast efficiently breaks down food waste , reducing its COD and BOD and is surprisingly efficient at digesting the environmentally troublesome lipid in food waste and so complex enzymatic treatment to deal with the lipid content of oriental food waste was not needed The efficient digestion of lipids by yeast was an unexpected result of the study which could have important implications for digestion of food wastes. The lack of need of a specific saccharification process for cooked rice based food waste and the efficiency of lipid digestion are two results of the present study useful for better modelling yeast digestion of food waste
