Technical Abstract: Acetone, butanol, and ethanol can be produced by Clostridia bacteria in anaerobic fermentation. Many of these organisms are also capable of using starch as carbons source. Therefore, we collected starch-rich sludge from the clarification of sweet sorghum juice and investigated if this material could be used as starting material for butanol production. The results show that it was possible to produce the solvents at titers similar, or higher, to those obtained when glucose was used as a substrate. The work will show the impact of adding external nutrients to improve productivity.
