The aim of the transfer project is to find optimal scientific and technical conditions for the application of laccase mediator systems (LMS) on wood fibers and curing the fibers with the hot-air/hot-steam process, which was developed in the preceding DFG projects.For this purpose, the results obtained will be transferred from the batch process into a continuous working system in collaboration with the Pfleiderer Company. The transfer project will also focus on basic research to understand the physical processes during hot air and hot steam applications and the related mode of action of the LMS. To scale up the process into industrial scale the results will be carefully analyzed. The technical objective of the research project is to modify the production conditions of the wood fiber insulation boards to the requirements of the LMS and to integrate the process technique of hot-air/hot-steam, which enable the production of binder-free wood fiber insulation boards. The duration of the project will be 36 months, as attempts to design and build the prototype plant are demanding and require a certain amount of time.The application of the hot-air/hot-steam process for the production of LMS-bonded wood fiber insulation boards are supposed to enrich white biotechnology with a completely new application field and additional customers from the insulation industry.For this purpose, it is planned to analyze the physical function and mode of action of the hot-air/hot-steam process and its influence on the ad- and cohesive mechanisms between the LMS-treated wood fibers. Also the role of the chemical wood components during LMS actions and the hot-air/hot-steam treatment will be investigated and has to be considered for the technical process.The prospect of success of this transfer project is expected to be high due to the positive results of the previos studies.

该转移项目的目的是寻找最佳的科学和技术条件，以将漆酶介体系统（LMS）应用于木纤维，并通过热空气/热蒸汽工艺固化纤维，该工艺是在之前的DFG项目中开发的。为此，所获得的结果将与Pfleiderer公司合作从间歇工艺转移到连续工作系统。该转让项目还将侧重于基础研究，以了解热空气和热蒸汽应用期间的物理过程以及 LMS 的相关作用模式。为了将该过程扩大到工业规模，将对结果进行仔细分析。该研究项目的技术目标是将木纤维保温板的生产条件修改为LMS的要求，并整合热风/热蒸汽工艺技术，从而能够生产无粘合剂木纤维保温板。该项目的工期为36个月，因为设计和建造原型工厂的尝试要求很高，需要一定的时间。应用热风/热蒸汽工艺生产LMS粘合木纤维保温板，应该为白色生物技术提供一个全新的应用领域和更多来自保温行业的客户。为此，计划分析热风/热蒸汽工艺及其物理功能和作用方式。 对 LMS 处理的木纤维之间的粘合和内聚机制的影响。此外，还将研究化学木材成分在 LMS 操作和热空气/热蒸汽处理过程中的作用，并在技术过程中予以考虑。由于之前研究的积极结果，预计该转移项目的成功前景很高。
