以乳业废水为有机碳源，在球形红杆菌o.u 001存在下进行光生物制氢研究。在9 klx光照下，以5 ~ 40 v/v %的废物浓度和0.36 g干wt/l的接种量进行分批试验。在40 v/v %的浓度下，光生成氢的体积最大，但在较低的废物浓度（5-10 v/v %）下，底物产量达到最大。底物和产物浓度的变化被用来确定动力学模型。恒定pH值接近7的应用允许将未经处理的废物用于光生物制氢，产量很高。
Dairy wastewater was applied as the source of organic carbon in photobiological generation of hydrogen in the presence of Rhodobacter sphaeroides O.U. 001. Experiments were performed as batch tests with concentration of the waste varying from 5 to 40 v/v %, and concentration of inoculum of 0.36 g dry wt/l under illumination of 9 klx. The highest volumes of photogenerated hydrogen were obtained at concentration of 40 v/v %, but the maximal substrate yield was reached for lower concentrations of the waste (5–10 v/v %). Changes in concentrations of substrates and products were used for determination of kinetic model. An application of constant pH close to 7 allows for use the non-treated waste in photobiological hydrogen generation with good yield.
