The变色 fungi inside the anti-corrosion wood flower架子 do not harm the cell wall tissue of the wood cells, but under suitable conditions, some of the fungi can erode the cell walls, leading to a decrease in cellulose, hemicellulose, and hot water extractable content. Due to the reduced cellulose and hemicellulose content in the wood cell walls, and the minimal damage to lignin and resin substances, the relative content of lignin and resin slightly increases.
