Effective Microorganisms Delignification of Empty Fruit Bunch as Co-Substrate in Palm Oil Mill Effluent Anaerobic Digestion
The Anaerobic Co-Digestion (ACD) of POME and EFB is widely applied to produce biogas by converting Chemical Oxygen Demand (COD). However, the lignin content in the EFB hinders the performance of the anaerobic bacteria. Therefore, this paper proposes EFB delignification by effective microorganisms (E...
