Ethanol production from lactose by extractive fermentation






Biotechnology letters 15(8): 871-876

Ethanol production from lactose by extractive fermentation

The suitability of extractive fermentation as a technique for the production of ethanol from lactose by Candida pseudotropicalis was examined as a potential improvement over conventional methods. A biocompatible solvent was selected through determination of the critical log P (octanol-water distribution coefficient) of the fermentation organism. Using Adol 85 NF, the selected solvent, extractive fed-batch and conventional fed-batch systems were operated for 160 h. The extractive system showed a 60% improvement in lactose consumption and ethanol production, as well as a 75% higher volumetric productivity.

Extractive fermentation is a technique that can be used to reduce the effect of end product inhibition through the use of a water-immiscible phase that removes fermentation products in situ. This has the beneficial effect of not only removing inhi...
