Effects of the influencing factors of photosynthetic bacteria group on hydrogen production

In this paper hydrogen production factors of efficiently hydrogen production photosynthetic bacteria group(EPSBG) were studied with glucose assubstrate. The result shows that anaerobic and illumination were required during hydrogen production with EPSBG. The better hydrogen production conditions of EPSBG were as follows: 2000～6000 lx illumination, 28～34℃ temperature, 5～8 ofpH value, 10%～100% inoculation， nitrate addition had little influence on hydrogen productivity. The observed maximal hydrogen bio-production rate was 39.6 mL H₂/g(COD)·d. This can provide high scientific reference value for the research of biological hydrogen production from solar energy.
