ABSTRACT
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 percent to 15.6 percent and from 15.8 percent to 12.3 percent, respectively. However in WS, hemicellulose decreased from 27.2 percent to 9.5 percent. Lignin broke down continuously in BS and WS, with 31.8 percent and 34.4 percent degradation, respectively; higher than that of cellulose. During the pinning stage, the CN 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).
