Enhanced methane production from algal biomass through short duration enzymatic pretreatment and codigestion with carbon rich waste

摘要: Anaerobic digestion of algal biomass faces problems low digestibility due to cell wall resistance and inappropriate carbon nitrogen ratio. In the present work a short duration method involving fungal crude enzyme based pretreatment was disclosed. The effect enzymes on assessed qualitatively through visual microscopic observations quantitatively measuring solubilization. Up 50% COD solubilization observed within 150 min under optimal conditions. Subsequent anaerobic pretreated showed production 324.38 mL CH4 g−1 VSfed as compared 254.73 from untreated biomass. Interestingly, methane yield increased up 413.89 when codigested with cattle dung. On other hand, sugarcane bagasse had negative codigestion its poor digestibility. Overall, attempt promising results by improving though codigestion.
