Abstract:
Sweet sorghum is considered an energy crop with lower water requirements to growth and it is a good substrate to anaerobic co-digestion with microalgae biomass, together they make an optimal nutrient balance. A semicontinuous regime in anaerobic co-digestion has been investigated for different OLR. Previously, batch experiments were evaluated for substrates in mono-digestion. The higher methane yield of the co-digestion was 239 L CH4 kg -1 -1-1 VSfeed and it corresponded to OLR of 1 g VS Ld. VFA/Alkalinity ratio, VFA concentrations and N-NH4 concentrations for experiments were below of the suggested limits for a stable anaerobic co-digestion process.
