引言光合细菌产氢具有底物转化效率高、吸收光谱范围广、无污染、能耗低、操作简单的优点[1-2]。目前,关于光合细菌的底物跨膜传输和产氢方面的理论研究相对较少[3-4]。Vrabl等[5-6]研究了葡萄糖的跨膜传输过程,分析了细胞膜上的载体蛋白运输特性;
Based on single photosynthetic bacterial cell in a batch reactor for bio-production of H2,a model was established for transport of glucose across membrane and production of hydrogen.The concentration distribution of glucose and hydrogen in the bioreactor was estimated,and the effect of light wavelength and intensity on glucose concentration in outside of cells as well as concentration profiles of hydrogen was investigated.The results showed that substantial agreement was achieved between the experimental results and model prediction values;and at wavelength and intensity of light 590 nm and 8000 lx respectively,the concentration of glucose was the lowest,and concentration of hydrogen was the highest outside cells.
