从经由一个混合文化黑暗发酵过程的未加工的木薯淀粉的简历氢的生产被调查。H 2 的生产收益被调整底层集中和微生物混合比率优化。1.72 摩尔 H 2/mol 葡萄糖的最大的 H 2 收益与 10 g/L 的木薯淀粉集中被获得给 90% 利用率。底层利用并且氢和不稳定的丰满的酸的产生的动力学也被调查。底层利用列在后面假首先订反应动力学,而两 H 2 的生产和 VFA 与 Gompertz 方程相关。这些结果证明那棵木薯是 biohydrogen 的生产的一个好候选人。
The production of bio-hydrogen from raw cassava starch via a mixed-culture dark fermentation process was investigated. The production yield of H2 was optimized by adjusting the substrate concentration and the microorganism mixture ratio. A maximum H2 yield of 1.72 mol H2/mol glucose was obtained with a cassava starch concentration of 10 g/L to give a 90% utilization rate. The kinetics of the substrate utilization and of the generation of both hydrogen and volatile fatty acids were also investigated. The substrate utilization follows pseudo first order reaction kinetics, whereas the production of both H2 and the VFAs correlate with the Gompertz equation. These results show that cassava is a good candidate for the production of biohydrogen.
