Gasification of sewage sludge allows the recovery of energy, and produces a mix of CO, CO2<\/sub> and H2<\/sub> called synthesis gas (or syngas), which can be fermented by acetogenic bacteria to added-value products. This work presents the conversion of syngas to organic acids and alcohols using both pure and mixed cultures. Pure culture kinetic experiments with Clostridium carboxidivorans<\/i> P7 resulted in the production of high concentrations of acetate (454 mgC\/L), and also ethanol (167 mgC\/L). The pH was the main factor driving solventogenesis, with about 50% of the products in the form of alcohols at pH 5. On the other hand, lab-scale experiments using a carboxydotrophic mixed culture from the genus Clostridium<\/i> enriched from anaerobic digester sludge of a municipal wastewater treatment plant was capable of producing mainly butyrate and butanol, with maximum concentrations of 1,184 mgC\/L and 277 mgC\/L, respectively.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
