Corn stalk pretreated with white-rot fungus Trametes hirsute was used to produce fiberboard by hot pressing without adhesive. The moduli of rupture and elasticity of the corn-stalk-based fiberboard were increased 3.40- and 8.87-fold when bio-pretreated rather than untreated corn stalk was used. Fourier transform infra-red spectroscopy, X-ray diffraction, and chemical analysis showed that bio-pretreated corn stalk increased the mechanical properties of the fiberboard because it had more than twice the number of hydroxyl group, an 18% higher crystallinity, and twice the polysaccharide content of untreated corn stalk. Its laccase content was 4.65 ± 0.38 U/g. Corn stalk-based fiberboard production did not require adhesives, thus eliminating a potential source of toxic emissions such as formaldehyde gas.
用白腐菌糙皮侧耳预处理的玉米秸秆，无需粘合剂，通过热压即可生产纤维板。与未预处理的玉米秸秆相比，生物预处理的玉米秸秆生产的秸秆纤维板的断裂模数和弹性提高了 3.40 倍和 8.87 倍。傅里叶变换红外光谱、X 射线衍射和化学分析表明，生物预处理的玉米秸秆增加了纤维板的机械性能，因为它的羟基数量是未处理玉米秸秆的两倍以上，结晶度提高了 18%，多糖含量是未处理玉米秸秆的两倍。其漆酶含量为 4.65±0.38 U/g。基于玉米秸秆的纤维板生产不需要粘合剂，因此消除了甲醛气体等有毒排放物的潜在来源。
