摘　　要：通过改变暗间歇时长,考察HAU-M1光合产氢细菌的生长及pH值和底物浓度的变化情况,研究暗间歇时长与光合细菌产氢量及其工艺参数之间的相关关系。实验结果表明:暗间歇时长为0(持续光照)、6、12、18h时,累计产氢量分别为351、380、275和181mL;反应器内的光合细菌浓度最大值分别为0.547、0.632、0.665和0.449g/L;反应残液的p H值分别为5.58、5.17、4.98和4.71。表明适宜的暗间歇时长可促进光合生物制氢反应过程中光合细菌的生长,同时有利于光合生物产氢过程的进行,可为光合生物制氢工艺技术的进一步优化和产业化发展提供科学参考。In the paper, dark cycle was changed in order to investigate the growth of PSB HAU-M1, and the changes of pH value and substrate concentration. The relationship between the dark cycle and hydrogen yield was evaluated. The results showed that when the dark cycles were 0 h, 6 h, 12 h, and 18 h, the cumulative hydrogen yields are 351 mL, 38OraL, 275 mL, and 181mL, respectively, the concentrations of PSB in the bioreactor were 0.547 g/L, 0.632 g/L, 0.665 g/L, and 0.449 g/L, and the pH value of the fermentative solution in the end of the reaction were 5.58, 5.17, 4.98, and 4.71, respectively. The diverse of the concentration of PSB and cumulative hydrogen yield indicted that optimal dark cycle could promote the growth of PSB, and is beneficial for the PHFP process. The research on the dark cycle in the PHFP process can provide scientific reference for further optimization and industrial development of PHFP technology.
