We focused on hydrogen production by purple photosynthetic bacteria as a renewable energy source. We studied the effect of medium pH on the growth and the hydrogen production activity of the bacteria, because ambient pH is an important factor when utilizing biomass resources or organic waste for this purpose. Rodopsedomonas palustris CGA009 was grown in the media with varying pH from 5.0 to 9.0. Lactate, butyrate, glycolate malate, malonate, and glucose were examined whether these were suitable carbon sources for hydrogen production. Medium pH was shown to have much influence on the bacterial growth and the hydrogen production activity. For example, in the media containing malonate, hydrogen production occurred only at pH 6.0, while bacterial growth with doubling time of ca. 6.0 h was observed from pH 6.0 to pH 8.0.
