When considered by a biorefinery approach, an agroindustrial byproduct such as wheat bran can find a new standing in the field of fabrication of mycelium-based materials. The present work reports on a systematic study on the effect of wheat bran as an upgrading feedstock for the growth and development of fully biobased and biodegradable composites. Two families of materials based on bran/cotton and bran/hemp mixtures were fabricated on an industrial scale. The natural materials thus obtained were fully characterized and their end-life was assessed in composting conditions. The research focusses on two main aspects: the nutritional contribution of bran for the fungal growth and its effect on the mechanical properties as a filler in the final composites. It must be noted that the valorization and exploitation of a byproduct such as bran can have a considerable impact on the industrial production of mycelium-based composite materials, by reducing the time of production while increasing their mechanical performances.

当考虑到生物精炼方法时，麦麸等农工业副产品可以在菌丝体材料制造领域找到新的地位。目前的工作报告了对麦麸作为升级原料对全生物基和可生物降解复合材料的生长和发展的影响的系统研究。基于麸皮/棉花和麸皮/大麻混合物的两类材料以工业规模制造。对由此获得的天然材料进行了充分表征，并在堆肥条件下评估了它们的使用寿命。研究集中在两个主要方面：麸皮对真菌生长的营养贡献及其作为最终复合材料中的填料对机械性能的影响。
