摘要

霉菌复合材料是一种可持续材料，由菌丝体与木质纤维素基质结合而成；这些成分结合在一起，创造出一种轻质、环保的传统材料替代品。本文尝试用蒸汽爆破（SE）作为预处理方法，以促进榉木上的多色曲霉（Trametes versicolor）的生长。在 SE 处理严重度（log R0）≤ 3.96 的情况下，真菌生长达到最佳状态。使用扫描电子显微镜（SEM）、氮测量和近红外光谱（NIRS）结合多元分析，对菌丝密度和菌丝复合体的异质性进行了表征和量化。结果表明，这些技术的结合可以量化材料中真菌密度与所用生长基质的关系。这些结果为真菌/基质选择的多标准优化铺平了道路，从而获得具有特定性能的真菌复合材料。

Steam Explosion: A Booster for Fungal Growth in a Myco-composite

A myco-composite is a sustainable material formed by combining mycelium with a lignocellulosic substrate; these components are binding together to create a light and eco-friendly alternative to traditional materials. In this paper, steam explosion (SE) was experimented as a pretreatment to promote the growth of Trametes versicolor on beech wood. An optimal fungal growth was observed for an SE treatment severity (log R₀) ≤ 3.96. Characterization and quantification of mycelium density and heterogeneity in the myco-composite were carried out using scanning electron microscopy (SEM), nitrogen measurement, and near-infrared spectroscopy (NIRS) combined with multivariate analysis. The combination of these techniques was shown to be relevant for quantifying the fungal density in the material in relation with the growing matrix used. These results pave the way for a multicriterion optimization of the fungal/matrix choices to obtain myco-composites with specific properties.
