The main object of this project is the improvement of Laccase-Mediator-Systems for the production of binder- and formaldehydefree wood fiber composites by using immobilised Laccases. An immobilisation of Laccase as primary step in fiberboard making offers ecological and economical opportunities. The Laccase enzyme will not remain within the wood composites like before, but it will be reuseable several times. The immobilised Laccase works as a catalyst, which oxidizes the Mediator. The oxidised Mediator then takes the role for the activiation of the wood fibers surface lignin. The application of immobilised Laccases is seen as an important milestone for the industrial production of wood fiber composites without conventional, petrochemical binder systems. The know-how of DFG-project EU 124/2-1 will be directly transfered to the applied project.

该项目的主要目标是通过使用固定化漆酶来改进漆酶-介质系统，以生产无粘合剂和无甲醛的木纤维复合材料。固定化漆酶作为纤维板制造的第一步提供了生态和经济的机会。漆酶不会像以前那样留在木质复合材料中，但它可以多次重复使用。固定化漆酶起催化剂作用，氧化中间体。氧化后的介质起到活化木纤维表面木质素的作用。固定化漆酶的应用被视为没有传统石化粘合剂系统的木纤维复合材料工业生产的一个重要里程碑。dfg项目EU 124/2-1的技术诀窍将直接转移到申请项目中。
