The method of producing hydrogen from organic waste water and solar energy using photosynthesis bacteria is environmental preservation type technology. However, the hydrogen manufacturing efficiency by this technology is very low, and has not resulted in utilization now. So, in this research, experimental examination was performed for the purpose of improvement in hydrogen manufacturing efficiency. The used photosynthesis bacteria are classified into Purple nonsulfur bacteria. A scientific name is Rhodopseudomonas Palustris. As a result of investigating the relation between a substrate given dose and the amount of hydrogen generating, the optimal amount of substrates for improving the raw efficiency from hydrogen was able to be specified. Moreover, comparison examination between the hydrogen production by the mixed culture system examined by previous report and it of a pure culture system was performed. Consequently, in pure culture, as compared with the case of mixed culture, improvement in the following hydrogen gas manufacturing efficiency was able to be confirmed. 1) The quantity of production (ml/cell) of the hydrogen per bacteria weight increased 214%. 2) The total hydrogen quantity of production (L/L*day) increased 183%. 3) Optical energy conversion efficiency increased 46%. As mentioned above, the fundamental data concerning the hydrogen gas production by photosynthesis bacteria was able to be obtained.
