Hydrogen can be generated from cyanobacteria cultivation with light and organic carbon as an energy source. The aim of this study was to investigate the influence of ammonium and glucose concentration, and the culture age on the production of hydrogen and other products, and phosphate and organic carbon removal by Anabaena sp. (UTEX 1448) in batch anaerobic photobioreactors. Our results demonstrated an effect of culture age and ammonium concentration in hydrogen production, an average increase of 4.1 times (90.4 μmol H₂ mg Chl a⁻¹ h⁻¹ and 13.2 mmol mg Chl a⁻¹) in the conditions with younger biomass and without ammonium. Culture age also had an effect in phosphate removal, with 92% of removal efficiency, and ethanol production (an average increase of 2.9 times–97 mg L⁻¹), however the optimum conditions were obtained with older biomass. This study demonstrates efficient hydrogen production by this strain of Anabaena sp. fewer researched.

可以通过使用光和有机碳作为能源的蓝细菌培养产生氢。这项研究的目的是研究铵和葡萄糖浓度，培养年龄对制氢和其他产物的生产以及鱼腥藻去除磷酸盐和有机碳的影响。（UTEX 1448）分批厌氧光生物反应器。我们的结果证明了培养年龄和铵浓度对制氢的影响，平均增加了4.1倍（90.4μmolH ₂ mg Chl a ^-1 h ^-1和13.2 mmol mg Chl a ^-1），且生物质年轻，无铵。培养年龄对除磷效果也有影响，除磷效率为92％，而且乙醇产量（平均增加2.9倍至97 mg L ^-1），但是最佳条件是使用较老的生物质。这项研究证明了该Anabaena sp。菌株的高效产氢。研究较少。
