48.微生物を用いた有機性廃棄物からの水素生産

The barley-, sweet potato-, rice sho-chu post-distillation sully which generated from sho-chu industry are organic acid rich waste. The biological hydrogen production from sweet potato sho-chu post-distillation sully by newly isolated bacteria was demonstrated. The highest hydrogen producing bacteria was isolated from 83 of sample locations. The bacterium, Clostridium sp. JPCC H-3 as the highest hydrogen producer was obtained from Amataki. The maximum hydrogen production rate of Clostridium sp. JPCC H-3 was obtained at 5.83±0.05ml/5ml-solution for 24hr under 40℃ and pH6.8. It was 1.5 times higher than that of Clostridium butylicum NIBC3315 as comparative strain. These results showed that sweet potato sho-chu post-distillation sully could be use substrates for hydrogen production and Clostridium sp. JPCC H-3 will be one of the suitable candidate for hydrogen production from sweet potato sho-chu post-distillation sully.
