Addition of vanillic acid, acetovanillone, and protocatechuic acid increased the rate of hydrolysis of xylan by as much as 18-50% at low concentrations, but reached maxima at about 0.05% concentration. Addition of vanillin caused a 15% improvement in xylan hydrolysis, while addition of guaiacol more than doubled the hydrolysis rate. Increasing concentrations of either lignin or black liquor also increased the hydrolysis rate of xylan. Circular dichroism spectroscopy indicated a change in the structure of xylanase in the presence of black liquor.}, number={3}, journal={JOURNAL OF BIOTECHNOLOGY}, author={Kaya, F and Heitmann, JA and Joyce, TW}, year={2000}, month={Jul}, pages={241–247} } @article{gerber_heitmann_joyce_buchert_siika-aho_1999, title={Adsorption of hemicellulases onto bleached kraft fibers}, volume={67}, ISSN={["0168-1656"]}, DOI={10.1016/S0168-1656(98)00163-1}, abstractNote={The presence of a cellulose binding domain was the main factor which influenced the adsorption of two Trichoderma reesei mannanases and a Trichoderma longibrachiatum xylanase onto bleached kraft fibers. The mannanase containing the binding domain adsorbed to a much greater extent than the mannanase and xylanase without binding domains. Once-dried fibers exhibited lower hemicellulase adsorption than the never-dried fibers. The adsorption onto once-dried fibers was only 30–50% the amount adsorbed onto virgin fibers. Adjustment of the ionic strength and pH of treatment was used to modify the charge on the fibers. Ionic strength had opposite effects on mannanase and mannanase core adsorption. Mannanase adsorption increased at high ionic strengths, while the mannanase core adsorption decreased. An increase in pH and fiber charge significantly enhanced the adsorption of xylanase.}, number={1}, journal={JOURNAL OF BIOTECHNOLOGY}, author={Gerber, PJ and Heitmann, JA and Joyce, TW and Buchert, J and Siika-aho, M}, year={1999}, month={Jan}, pages={67–75} } @article{kaya_heitmann_joyce_1999, title={Effect of dissolved lignin and related compounds on the enzymatic hydrolysis of cellulose model compound}, volume={33}, number={3-4}, journal={Cellulose Chemistry and Technology}, author={Kaya, F. and Heitmann, J.

Diffusion was enhanced by pretreating sycamore (Platanus occidentalis) sapwood with enzymes. Tangential diffusion was increased by 26%, while longitudinal diffusion was increased by approximately 110% in the enzyme treated samples of sycamore sapwood. Sycamore chips were pretreated using cellulase/hemicellulase/pectinase mixtures prior to conventional kraft pulping. After enzyme pretreatment followed by kraft pulping, the kappa number of the control was as much as 10% higher than the treated chips. In addition, enzyme treated pulps required less (approximately 9 kg ClO2/ ton pulp bleached) than the control. Pulp strength properties for the pretreated chips were comparable to kraft pulps receiving no enzyme pretreatments. Pulp viscosity was lower in pulps treated with cellulase/hemicellulase alone.}, booktitle={Enzyme applications in fiber processing}, publisher={Washington, DC: American Chemical Society}, author={Jacobs-Young, C.

Xylanases from Trichoderma have been purified and characterized in an effort to better understand the behavior of the various components of the xylanolytic system in order to optimize their effect. However, purification and characterization of xylanases from Trichoderma species are still incomplete. This review organizes current techniques for xylanase purification and examines the properties of xylanases that have been previously characterized. Problems with assays, lyophilizing, gel permeation behavior, gel electrophoresis and developing are also noted. From this review, a strategy for the isolation of an endoxylanase from a commercial preparation of T. longibrachiatum is developed.}, number={2}, journal={BIORESOURCE TECHNOLOGY}, author={Gerber, PJ and Heitmann, JA and Joyce, TW}, year={1997}, month={Aug}, pages={127–140} } @misc{chang_joyce_kirk_1987, title={Process of treating effluent from a pulp or papermaking operation}, volume={4,655,926}, number={1987 Apr. 7}, publisher={Washington, DC: U.S. Patent and Trademark Office}, author={Chang, H.
