Abstract:

实验研究了底物初始浓度对光合细菌产氢动力学特性的影响,并对光合细菌产氢得率和初始底物转化为氢气得率进行比较,分析底物初始浓度对光合细菌产氢代谢的影响,实验发现底物初始浓度为120mmol/L时最适合光合细菌的产氢代谢,底物初始浓度达到140mmol/L时,光合细菌主要进行生物量合成和产酸代谢,得到各浓度梯度下的最大生物量,但对产氢代谢产生抑制作用,表明最大生物量与最大的产氢能力之间不成正比关系及光合细菌产生CO2机制与产氢机制不同;光合细菌最大比产氢活性表现在对数生长期,最大生物量出现在稳定期。实验证明,光合细菌对数生长期受底物浓度影响大,底物浓度低,最大生物量所对应的时间相对较早,底物浓度增大,最大生物量所对应的时间相对延后。
