Summary

This chapter on extraction-fermentation hybrid (extractive fermentation) reviews recent advances in separation technologies that can be used in the slip-stream approach for in situ recovery of fermentation products, focusing on carboxylic acids and alcohols. First, the chapter provides an introduction to industrial needs for integrated fermentation-separation processes and their benefits to the biorefinery industry. A brief description of the basic principles of extractive fermentation and more detailed discussion of the design and operation of various in situ product recovery techniques follws. Finally, two extractive fermentation examples are illustrated, one for biobutanol production and the other for butyric acid production by Clostridia. Both of them are still at the laboratory-scale research and development stage, but hold great promise for industrial application. Lastly, a conclusion and some perspectives about the future trend in this technology area are provided.
