To improve its 1,3-propanediol (1,3-PD) production, Clostridium butyricum was cultivated on glycerol medium supplemented with cassava pulp (CP). At small concentrations, the CP improved the 1,3-PD productivity of C. butyricum from (0.25+/-0.01)g/L/h (glycerol alone) to (0.43+/-0.02)g/L/h (glycerol+2g/L CP) after 24h fermentation.
