چکیده :

The structural, biometry and chemical changes were investigated in Hornbeam (Carpinus betulus) chips that had been exposed to phanerochaete chrysosporium BKM-1767 fungus. Samples subjected to fungal treatments for durations of 1, 2 and 4 weeks were investigated and compared with a control sample not subjected to fungal treatment. There was a significant difference between experimental samples (treated and iuntreated samples) in cell wall thickness, chemical properties and loss weight. So that, the cell wall thickness and lignin values were decreased and cellulose was increasing after treatment. Results of scanning electron microscopy showed that fungal hyphae were present on the surfaces of all chips exposed to the fungus. In the treated samples for a 2 or 4-week period, these hyphae additionally penetrated into vessels and lumens through ray cells, softening and destroying the cell walls.
