Butyric acid production from glucose and xylose, respectively, as carbon source in free-cell and FBB fermentations. The fermentation was operated at the fed-batch mode to reach the maximum butyric acid concentration. a Free-cell fermentation of glucose; b FBB fermentation of glucose; c free-cell fermentation of xylose; d FBB fermentation of xylose
