초록

This study was conducted to investigate the effect of thermal pre-treatment on bio-hydrogen from food waste. Two continuous reactors operated and VFAs(volatile fatty acids) production and microbial communities were analyzed. The average hydrogen yield was 0.50 and 0.33mol $H_2/mol$ $hexose_{added}$ in thermally treated food added reactor(R1) and control(R2), respectively. Butyrate concentration was similarly 7,500mg/L in both reactors, but two times higher lactate concentration was observed in R2(3,800mg/L). The results of FISH(fluorescence in situ hybridization) showed that the relative microorganism to hydrogen producing bacteria was 78 and 27% in R1 and R2, respectively.
