Improvement of Laccase-Mediator-Systems for the production of binder- and formaldehyde-free wood fiber composites by using immobilised Laccases.

该项目的主要目的是改进漆酶介体系统，通过使用固定化漆酶生产无粘结剂和无甲醛的木纤维复合材料。漆酶的固定化作为纤维板制造的主要步骤提供了生态和经济的机会。漆酶不会像以前那样留在木材复合材料中，但它可以重复使用多次。固定化的漆酶作为催化剂，其氧化介体。氧化后的介体则起到活化木质纤维表面木质素的作用。固定化漆酶的应用被认为是工业生产木纤维复合材料而无需常规石化粘合剂系统的重要里程碑。DFG项目EU 124/2-1的专有技术将直接转移到申请项目。

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.
