摘要

Hydrogen production by anaerobic mixed culture was studied at 35℃ and pH 5.5 in a continuous-stirred tank reactor (CSTR) using glucose as a carbon source. The variations of hydraulic retention time (HRT) affected on hydrogen production were investigated. The biogas composition, hydrogen production rate, and hydrogen yield increased when hydraulic retention time was decreased. The biogas contained 38.5 - 73.9% hydrogen and the hydrogen production rate ranged from 0.50 to 3.34 LH_2/L/d. Furthermore, the hydrogen yield increased from 0.62 to 1.24 mol-H_2/mol-glucose. The morphology of hydrogen-producing bacteria was composed of diplobacilli. The microbial communities of anaerobic mixed culture were also investigated by the restriction fragment length polymorphism analysis. Clostridia and Bacilli were predominant populations in the continuous stirred-tank reactor.
