Biocatalysts are promising alternatives to conventional chemical catalysts, because they are able to realize reactions under ambient conditions. Since these enzymes show often comparable low process stabilities, immobilization is highly interesting to increase stability and productivity. During this study immobilization via spray congealing was investigated as new immobilization technique to increase the enzyme stability. In addition, a laccase was immobilized with this method and tested for C-N coupling reactions of catechols and amines to synthezise new interesting building blocks.<eng>
