Objective:
To evaluate pretreatment requirements and conversion efficiencies of lignocellulosic feedstocks into fermentation products using mixed culture bioreactors. Develop conversion technologies for conversion of fermentation acids into solvents (i.e., butanol).

Approach:
Untreated and pretreated corn fiber will be fed to a mixed culture bioreactor that is optimized for the production of butyric acid. Product butyric acid will then be converted by solventogenic clostridia to produce fuel butanol.
