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±0.38U/g. Corn stalk-based fiberboard production did not require adhesives, thus eliminating a potential source of toxic emissions such as formaldehyde gas.
