Biofuel production from birch wood by combining high solid loading simultaneous saccharification and fermentation and anaerobic digestion

Inhibitors generated during pretreatment of lignocellulosic biomass may affect the subsequent biochemical conversion to biofuels. In the present study, we tested 6 different reducing agents for their ability to detoxify steam-exploded birch used for ethanol production in a simultaneous saccharification and fermentation process. Cysteine, which was the most efficient detoxifying agent, increased both ethanol productivity and ethanol yield from...
