Abstract

Wood chips and sawdust are used for cultivating Ganoderma lucidum mushrooms. In Northern Europe, side-streams of Pinus sylvestris are highly abundant, however as cultivation substrate they inhibit the growth of G. lucidum. To identify the changes in lignocellulosic composition after fungal degradation, the major lignocellulosic components in P. sylvestris and an optimal substrate for G. lucidum, Populus tremula were analyzed. Populus tremula was evenly degraded while the glucan fraction of P. sylvestris was not degraded and its lignin fraction was consumed almost completely. Despite not being an optimal substrate, P. sylvestris was successfully delignified by G. lucidum.

灵芝菌种对欧洲赤松和欧洲山杨的降解作用

木屑和锯屑用于栽培灵芝蘑菇。在北欧，欧洲赤松（Pinus sylvestris）的侧流非常丰富，但作为栽培基质，它们会抑制灵芝的生长。为了确定真菌降解后木质纤维素成分的变化，我们分析了欧洲侧柏中的主要木质纤维素成分，以及一种最适合灵芝生长的基质--震颤杨。杨树被均匀降解，而西洋杉的葡聚糖部分没有被降解，其木质素部分几乎被完全消耗。尽管杨树不是一种最佳的底物，但它还是成功地被鹅掌楸脱木质。
