摘要:
以发酵液中溶解的一氧化碳(CO)为底物,研究高温嗜热菌(Carboxydothermus hydrogenoformans)厌氧发酵制氢的工艺过程. 通过C. hydrogenoformans菌的生长规律、絮凝能力和反应特性等实验研究,建立菌株的生长规律模型,得出微生物衰减系数和最大比生长速率. 结果表明,C. hydrogenoformans菌产氢率高,絮凝效果好,用于连续CO生物发酵制氢工艺是可行的. 对发酵制氢过程的影响因素进行考察,得出最佳食微比及CO对发酵制氢过程的抑制浓度等过程参数,为有效开发CO厌氧生物发酵制氢的工艺路线提供了参考依据. 图4 表2 参17
Abstract:
The biohydrogen production from anaerobic fermentation was studied with thermophilic bacterium Carboxydothermus hydrogenoformans using carbon monoxide (CO) dissolved in fermentation broth as the substrate. Bacterium growth model, decay efficient and the maximum specific growth rate were observed based on the experimental study of biomass growing, flocculation and microbial characteristics. The results indicated the feasibility of continuous anaerobic fermentation for hydrogen production from CO with C. hydrogenoformans due to its good hydrogen yield and flocculation ability. Furthermore, by investigating the effect of procedure parameters during CO fermentation, the optimal feed/microorganism was proposed and the maximum CO concentration was observed to avoid CO inhibition which was the key factor to consider in the study of continuous biohydrogen production from CO fermentation.
