| 摘 要： | 以光合细菌混合菌群为实验菌种，采用单因子实验方法，研究光合细菌产氢系统累积热量对产氢量的影响。结果表明：当初始温度较低时，系统累积热量有利于产氢量的提高，而初始温度高于30℃时，累积热量不利于产氢量的提高；光照强度在500～3 000 lx范围内，系统累积热量有利于产氢量的提高，并且光照强度越大，累积热量越多，产氢量增加也越多；接种量在5％～50％时，系统的累积热量也有利于产氢量的提高，其中，5%，10%，20%，50%接种的系统产氢量分别增加了43，89，103，30 mL. |

| Abstract： | The influence of different heat accumulation resulting from external factors on hydrogen production of photosynthetic bacteria was investigated in this paper. The results indicated that heat accumulation improved hydrogen production of photosynthetic bacteria when the initial temperature was low. However, when the temperature was higher than 30℃, it did not. Heat accumulation showed an upward trend with light intensity increasing from 500 to 3 000 lx，and was conducive to the improvement of hydrogen production. In other words, the more heat accumulation, the more hydrogen production yields. When the scope of inoculation was from 5% to 50%, heat accumulation was also conducive to the improvement of hydrogen production capacity. When inoculation was 5%, 10%, 20% and 50%, hydrogen production yields increased correspondingly by 43, 89, 103 and 30 mL. |
