Abstract:
为了解光合细菌的产氢机理，对沼泽红假单胞光合产氢菌cqk-01在光生物平板反应器中进行序批次培养，以470nmled灯提供连续光照，葡萄糖为碳源底物，研究不同初始酸碱条件下产氢光合细菌的生长特性、产氢特性以及能量转化效率.结果表明，在弱碱性条件下最适宜产氢光合细菌的生长；在反应液为酸性条件下，光合细菌具有较高的产氢量、产氢速率和能量转化效率，然而产氢纯度随着初始ph值的增大而升高；在温度30℃、光照强度1000lx、底物浓度75mmol/l的实验条件下，光合细菌的最佳产氢ph值为7.0，实验中最大累积产氢量为8.0mmol，最大产氢速率为3.39mmolg-1(celldryweight)h-1，产氢纯度高达70%，底物能量转化效率最大为1.98%，光能转化效率最大为7.7%.图6参18
