Use of xylanase and arabinofuranosidase for arabinose removal from unbleached kraft pulp.

Preparations of arabinofuranosidase and xylanase, respectively from Aureobasidium pullulans and Trichoderma longibrachiatum, were used to remove selectively xylose and arabinose from kraft pulp. The equilibrium moisture content of pulps treated with both enzymes, at varying relative humidities, revealed a consistently lower percent moisture content at all humidity set points. Shorter fiber lengths indicated some deterioration when pulp was exposed to high concentrations of both enzymes.
