| Popis: |
Three different examples of enzyme emulsions are presented. The enzymes are immobilized in liquid surfactant membranes. The effect of the organic membrane phase is discussed as well as the influence of the membrane composition on the transport of substrates and products through the membrane. An enzyme emulsion system for the production of l -leucine with continuous co-factor regeneration is described. It is not necessary to increase the molecular weight of the co-factor by linking it to a soluble high molecular weight compound (e.g., PEG), since the coenzyme cannot pass the liquid membrane without a suitable carrier. Also, a product (6-APA) can be enriched in the internal phase of the liquid membrane. The separation effect is not based on differences in molecular weight, but on the chemical behavior of the substances to be separated. |
