Abstract

A commercial three-layer particleboard served as model furniture for testing pretreatment with the oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm.) over 9-, 12-, 16-, and 20-week periods based on the effects of reducing the enzymatic resistance of component cellulose. The effects of pretreatment were assessed based on Fourier-transform infrared spectroscopy (FTIR) of the treated particleboards, wherein indexes (peaks and peak ratios) connected with parameters influencing enzymatic cellulose hydrolysis were analysed. The data were analysed in two ways: the measurement of peak heights in both primary spectra and deconvoluted spectra. The peak heights for the determination of the total crystallinity index (TCI) were measured according to narrow and broad baselines. Time and how indexes are calculated were found to be the main factors significantly influencing the values of indexes of pretreatment in most cases. Until week 9, P. ostreatus pretreatment seems to be advantageous for biofuel production, which was illustrated by decreases in the intensity of the 1735 and 1505 cm−1 peaks and A1505/A1735, A1505/A1375, A1505/A1158, and A1505/A896 ratios in addition to a reduction in crystallinity.
