摘要：Algae biomass has strong and complex cell wall structure that is a hindrance for microbial digestio n. In this work, two extracted algae biomass, which are freeze dried and spray dried Chlorella vulgaris biomass is applied to investigate the generation of bioelectricity by using single chamber air-cathode Microbial Fuel Cell (MFC). MFC was fed with freeze-dried algae powder to produce energy and determine its degrad ation efficiency. MFC with freeze-dried algae biomass was generating voltage around 739 mV from bacterial metabolism with algae substrate and phosphate buffered medium. Based on the power curve obtained, the maximum power density is 15 9 mW/m 2 with 2.5 g/L of substrate concentration. The Chemical Oxygen Demand (COD) removal efficiency is 5 4.2% and Coulombic efficiency (CE) obtained is 28.4%.
