| Abstract | This research aims to apply food waste for bioethanol production through biological process. In order to increase the fermentation efficiency, the fungal mash of Aspergillus oryzae TISTR 3018 was used for saccharification of food waste. The suitable hydrolysis conditions were 5% (w/v) of fungal spore loading under semi-solid state at room temperature (28.92 ? 0.56?C) for 72 h. Using those optimal conditions, the reducing sugar concentration was obtained, 59.23 ? 0.36 g/L or 0.30 g/g dried food waste. Non-sterilized food waste hydrolysate without solid residue separation was used for bioethanol fermentation by Saccharomyces cerevisiae. The highest bioethanol (crude bioethanol) of 33.4 g/L which calculated as 0.17 g/g dried food waste was achieved at 120 h of fermentation. The crude bioethanol was further utilized as biofuel for electricity generation by direct ethanol fuel cell. It was found that crude bioethanol exhibited the maximum current density of 0.48 mA.cm-2 at 0.57 V. This research demonstrated that food waste was usable as renewable raw material for bioethanol production and can also solve the environmental problem and energy scarcity problem in the future. |
