초록

This study was conducted to evaluate the characteristics of mesophilic fermentative $H_2$ production from food waste which was treated by food waste disposer. It was found that $H_2$ yield and lag phase were affected by particle size of food waste. The $H_2$ yield decreased with increasing particle size while lag phase increased. The maximum $H_2$ yield was found $0.584{\pm}0.03$ mol $H_2$/mol hexose at particle size smaller than 0.30 mm. The $H_2$ production rate was also affected by chemical composition of food waste. The $H_2$ production rate linearly decreased with increasing proteins to carbohydrates ratio(P/C ratio) where the maximum value was $0.031{\pm}0.006$ mol $H_2$/mol hexose h at 0.17.
