Abstract

A water-supported enzymatic reaction is carried out with the substrate and the enzyme present in the solid phase. Either the water does not form a liquid continuum around substrate and enzyme, or the water acts at least partially out of the gas phase, or the water required for the reaction is added via a solid, or at least a part of the water required for the reaction is transferred by means of solid body contacts or by a combination of these means. The reaction mixture can be mixed by ultrasound or turbulence, e.g. in a fluidized bed, or both.
