Abstract

Cationic polyelectrolytes can increase the cellulase-induced hydrolysis rates of bleached wood fiber. We show that the polymer associates mainly with the amorphous region of fiber and acts principally on endoglucanase. Fiber/water partitioning of the enzyme follows a Langmuir isotherm for the untreated fiber but a Freundlich isotherm is obeyed for the polymer-treated fiber.
