Performance of batch solid state fermentation for hydrogen production using ground wheat residue

International journal of hydrogen energy

Ozmihci, S.

Ground wheat (21 g) was subjected to batch solid state dark fermentation for bio-hydrogen production. Clostridium acetobutylicum (B-527) was used as the culture of dark fermentation bacteria at mesophilic conditions. Effects of moisture content on the rate and yield of bio-hydrogen formation were investigated. The highest CHF (1222 ml), hydrogen yield (63 ml H<SUB>2</SUB> g<SUP>-1</SUP> starch), formation rate (10.64 ml H<SUB>2</SUB> g<SUP>-1</SUP> starch h<SUP>-1</SUP>) and specific hydrogen formation rate (0.28 ml H<SUB>2</SUB> g<SUP>-1</SUP> biomass h<SUP>-1</SUP>) were obtained with a moisture content of 80%. Nearly complete starch hydrolysis and glucose fermentation were achieved with more than 80% moisture content and the highest substrate conversion rate (21.9 mg L<SUP>-1</SUP> h<SUP>-1</SUP>) was obtained with 90% moisture content at batch solid state fermentation producing volatile fatty acids (VFA) and H<SUB>2</SUB>.
