Abstract

This is an overview of the butanol (usually called acetone butanol ethanol, ABE) fermentation in various types of reactor systems and recovery by gas stripping. Gas stripping is a simple technique which does not require expensive apparatus, does not harm the culture, does not remove nutrients and reaction intermediates and reduces butanol toxicity (inhibition). As a result of butanol removal by gas stripping, concentrated sugar solutions can be used to produce butanol/ABE. Compared to sugar utilization of 30 gl−1 in a control batch reactor, sugar utilization of 199 gl−1 has been reported with 69.7 gl−1 solvent production. In fed-batch reactors concentrated sugar solutions (350 gl−1) have been used. Additionally, the process of ABE production results in concentrated product streams containing 9.1–120 gl−1 butanol/ABE. In the integrated ABE production and recovery systems, selectivities of 4–30.5 have been reported.
