摘　　要：研究了吸附法固定光合细菌的产氢能力,结果表明采用不同的吸附材料固定光合细菌,其产氢能力与游离态细菌相比均有提高。产氢能力最好的是大粒经陶粒,平均总产氢量达到452.7mL是对照组游离态细菌总产氢量的2.16倍,平均产氢速率是对照组的1.95倍,小粒径陶粒的产氢能力次之,平均总产氢量是对照组的1.72倍,平均产氢速率是对照组的1.73倍,沙砾和大孔树脂的产氢能力低于陶粒,但优于游离态细菌,产氢量分别是对照组的1.43倍和1.09倍,产氢速率分别是对照组的1.34倍和1.08倍。研究还发现采用吸附法固定光合细菌进行产氢,不仅能提高产氢能力,而且能提高氢气含量,延长产氢时间。The hydrogen production capacity of immobilized photosynthetic bacteria（PSB） cells on different Absorb material was investigated. Results indicate that they have different extensive improvement compared with free PSB cells. Hydrogen production capacity of the bigger ceramsite is the best. The amount of hydrogen production equal to 452.7 mL, which is 2.16 times for free PSB cells on average, and velocity is 1.95 times. The capacity of the smaller ceramsite followed, its amount is 1.72 times, and velocity is the 1.73 times as much as free PSB cells. The hydrogen production capacity of Pebbles and macroporous resin is lower than ceramsite, but higher than free PSB cells. The amount of hydrogen production respectively is 1.43 and 1.09 times, and its velocity is 1.34 and 1.08 times, compared with free PSB cells. The study also finds that immobilized PSB not only can improve hydrogen production capacity, but also can improve ratio of hydrogen and extend hydrogen production time.
