| 摘 要： | 在10 L的发酵罐中,按照糖蜜的主要成分配制发酵培养基,考察和分析了批式、半连续发酵方式下,环境因素对固定化陶粒中厌氧菌发酵产氢的影响。结果表明,批式发酵产氢以糖蜜为底物的产氢得率、氢浓度和产氢速率分别为1.40 mol/mol蔗糖,53%和240 mL/(L.h)。可以在工业制氢中作为糖蜜快速发酵制氢的方法。

| Abstract: | The impact of the environmental factors on hydrogen production is studied and analyzed with the batch,semi-continuous fermentation in 10 L fermentation tank.Anaerobic bacteria is immobilized inside the ceramic,and the fermentation medium is in accordance with the main component of molasses.The results show that hydrogen production by batch fermentation of molasses as substrate is much more efficient than by semi-continues culture.And the yield,hydrogen concentration and hydrogen production rates were 1.40 mol/mol sucrose,53% and 240 mL/(L·h) separately.So,it's a good method for rapid hydrogen production by fermentation with molasses in industry. |
