co厌氧发酵制氢过程中的微生物特性及其影响因素
DOI: 10.3724/SP.J.1145.2012.00656, PP. 656-660
Keywords: 生物制氢,厌氧发酵,嗜热微生物,一氧化碳,底物抑制
Abstract:
以发酵液中溶解的一氧化碳（co）为底物，研究高温嗜热菌（carboxydothermushydrogenoformans）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
