The chemical changes in barley-straw (BS), wheat-straw (WS) and vineyard-pruning (VP) substrates were determined during colonization of Lentinula edodes mycelia (during primordium development) in solid state fermentation. Primordia appeared 39-50 days after inoculation. VP appeared to promote early sporophore initiation. The concentration of hemicellulose in BS and VP decreased gradually from 25.5% to 15.6% and from 15.8% to 12.3%, respectively. However in WS, hemicellulose decreased from 27.2% to 9.5%. Lignin broke down continuously in BS and WS, with 31.8% and 34.4% degradation, respectively; higher than that of cellulose. During the pinning stage, the C:N ratio decreased in VP and BS, but not in WS. On all substrates the phenols decreased notably throughout the first week of mycelial growth. The time elapsed (days) to pinning was positively correlated with cellulose content (r=0.89), total sugar (r=0.85) and inversely correlated to lignin (r=-1.00) and phenol content (r=-0.55).
在固态发酵中，研究了香菇菌丝体（原基发育期间）定殖时大麦秸秆（BS）、小麦秸秆（WS）和葡萄园修剪物（VP）基质的化学变化。接种后 39-50 天出现原基。VP 似乎促进了早期孢子体的启动。BS 和 VP 中的半纤维素浓度逐渐从 25.5%降至 15.6%和从 15.8%降至 12.3%。然而，WS 中的半纤维素从 27.2%降至 9.5%。BS 和 WS 中的木质素不断分解，分别降解 31.8%和 34.4%；高于纤维素。在钉状阶段，VP 和 BS 中的 C：N 比下降，但 WS 中没有。在所有基质上，酚类物质在菌丝生长的第一周内显著减少。到钉状阶段的时间（天）与纤维素含量（r=0.89）、总糖（r=0.85）呈正相关，与木质素（r=-1.00）和酚类物质（r=-0.55）呈负相关。
