음식물쓰레기의 생물학적 수소생산 및 미생물의 군집특성

Hydrogen gas production of anaerobic fermentative process from food waste as a substrate was 3.47 mg H2/g COD. The hydrogen production was little less than the synthetic wastewater with sucrose as a substrate (7.56 mg H2/g COD). The B/A ratios of the synthetic wastewater and food waste were 3.73 or 8.01 respectively. Butyric acid was more produced when hydrogen production was higher. Microbial community in the samples was analyzed as Escherichia sp., Klebsiella sp., Clostridium sp., Bacterium sp., and Enterobacter sp. Clostridium sp. was detected both samples but Klebsiella sp. was more active with fermentation process of the food waste. Taxonomic description shows that 60% of the microorganism was γ-proteobacteria and Firmicute and Bacteria was 20% respectively.
