Ethanol production from lactose by extractive fermentation

, : Ethanol production from lactose by extractive fermentation. Biotechnology letters 15(8): 871-876

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.

Few bony injuries and most soft tissue injuries cannot be detected on plain radiography. Magnetic resonance imaging (MRI) can detect such occult bony injuries due to signal changes in bone marrow. In addition to excluding serious bony injuries, it...
