Abstract

A biocatalytic method for reacting organic, especially poorly water-soluble substances. Enzymes, prokariotic and eukariotic cells or combinations of enzymes and cells are immobilized in lyotropic liquid crystals (mesophases), preferably with inverse phase structure. The supply of substrate and the removal of product are performed via one or more solvent phases. Organic solvents function as solvent phases. In addition, an aqueous solvent phase can also be present. In order to produce these two and three-phase systems, three-component systems consisting of water, organic solvent and surfactant are used.
