Abstract

Mushroom strains of Polyporales from the genera Coriolus, Trametes, Pycnoporus, Ganoderma, and Formitella were explored in terms of mycelial growth characteristics for the application of mushroom mycelia as alternative sources of materials replacing fossil fuel-based materials. Among the 64 strains of Polyporales, G. lucidum LBS5496GL was selected as the best candidate because it showed fast mycelial growth with high mycelial strength in both the sawdust-based solid medium and the potato dextrose liquid plate medium. Some of the Polyporales in this study have shown good mycelial growth, however, they mostly formed mycelial mat of weak physical strength. The higher physical strength of mycelial mat by G. lucidum LBS5496GL was attributed to its thick hyphae with the diameter of 13 µm as revealed by scanning electron microscopic analysis whereas the hyphae of others exhibited less than 2 µm. Glycerol and skim milk supported the best mycelial growth of LBS5496GL as a carbon and a nitrogen source, respectively.

摘要

从属多孔菌的菌株蘑菇云芝，栓菌属，密孔菌属，灵芝，和Formitella在对蘑菇菌丝体的应用作为替代矿物燃料为基础的材料的材料替代来源菌丝生长特性方面进行了探索。在 64 株多孔菌中，灵芝LBS5496GL 被选为最佳候选者，因为它在基于锯末的固体培养基和马铃薯葡萄糖液体平板培养基中均显示出快速的菌丝生长和高菌丝强度。本研究中部分多孔菌菌丝生长良好，但大多形成体力较弱的菌丝垫。灵芝LBS5496GL的菌丝垫具有较高的物理强度，这归因于其通过扫描电子显微镜分析发现的直径为 13 µm 的厚菌丝，而其他菌丝则小于 2 µm。甘油和脱脂牛奶分别支持 LBS5496GL 作为碳源和氮源的最佳菌丝生长。
