Effects of Phosphate on Fermentative Biohydrogen Production of Biohydrogenbacterium R3 sp.nov.

Abstract:

This study has investigated the effects of K2HPO4 to the cell growth and hydrogen production ration to Biohydrogenbacterium R3 sp.nov.. The results found that: K2HPO4 can promote the cell growth and hydrogen production effectively and it can maintain the pH value stably in culture. The biogas yield, hydrogen production yield and specific hydrogen production ration had the maximum of 4960 ml/L, 2107.5 ml/L and 1.93 mol H2/mol glucose respectively when the concentration of K2HPO4 was 1.5g/L. The final pH in the culture was always kept at 3.0~5.0.
