Treatment of agro-industrial wastewater using microalgae-bacteria consortium combined with anaerobic digestion of the produced biomass

► Two agroindustrial wastewaters are used as culture medium for microalgae production. ► Phosphorous limitation triggers lipid accumulation in produced biomass. ► Anaerobic batch experiments are carried out using the produced biomass. ► Lower TCOD/VS ratio (0.5) promotes higher methane yield. ► The higher lipid content (30%), the higher methane yield.
