【摘要】 探讨了丙酸型发酵菌群对葡萄糖、果糖、半乳糖和阿拉伯糖等四种单糖的发酵产氢特性。结果表明,葡萄糖是最易被丙酸型发酵菌群利用和拥有最高产氢能力的单糖,其次是果糖和半乳糖。由于阿拉伯糖代谢途径的特殊性,在丙酸型发酵菌群作用下不仅其产氢能力比较低,而且在转化之前需要较葡萄糖、果糖和半乳糖更长的调节适应期。更多还原

【Abstract】 Hydrogen production from glucose, fructose, galactose and arabinose by propionic acid type fermentation flora was investigated by batch culture. The results showed that glucose was the optimum monocase for propionic acid type fermentation flora to produce hydrogen while fructose and galactose came secondly with a similar hydrogen yield. Arabinose released less hydrogen than the three hexose mentioned above due to the complicacy of its degradation process and the need of more special enzymes. Farther more, a longer acclimation course was showed before the fermentation flora could ferment arabinose in the batch culture.更多还原
