A 4.34 liter two-stage air-lift photobioreactor incorporatingAnabaena variabilis ATCC29413 mutant PK84 was used to study H₂ production. Results showed that H₂ production increased with increasing light intensity from 47 μE/(m²·s) up to 190 μE/(m²·s), but that further increase of light intensity decreased the H₂ production because of the inhibition due to the high pO₂. The data also indicated that longer argon gas charge resulted in more H₂ produced due to the increase of nitrogenase activities and heterocyst frequency, and that more than 1.3 L net H₂ was produced from this computer controlled photobioreactor.  相似文献

采用气升式光生物反应器培养系统, 进行了通气速率、氮浓度、Fe3+浓度、IAA浓度、CO2补充量等环境因子对蛋白核小球藻生长和油脂积累影响的研究。结果表明, 通气速率为2.0L/min时小球藻的生长速率和油脂产量最大分别为6.17mg/(L·d)和1.77mg/(L·d); 实验范围内氮浓度对小球藻油脂产量影响规律性不强; Fe3+浓度为0.1mmol/L时小球藻的生长速率最大为7.29mg/(L·d), Fe3+浓度为1.0mmol/L时小球藻油脂产量最高为2.54mg/(L·d); IAA浓度为1.0mg/L时小球藻的生长速率为7.47mg/(L·d), 油脂产量为2.89mg/(L·d), 二者都达到最大值; CO2补充量为6000mL/d时小球藻的生长速率最大为9.88mg/(L·d), 补充量为4000mL/d时小球藻油脂产量最高为3.86mg/(L·d)。经过条件优化, 小球藻油脂产量得到了显著的提高。  相似文献
