Integration of first and second generation biofuels: Fermentative hydrogen production from wheat grain and straw

- The feasibility of integrating lignocellulose- and starch-rich biomass-based hydrogen production was investigated with the extreme thermophilic bacterium Caldicellulosiruptor saccharolyticus.
- Wheat grain hydrolysate showed limited fermentability whereas wheat straw hydrolysate showed relatively good fermentability.
- The mixed hydrolysate showed good fermentability at the highest tested sugar concentration.
