摘要：Wood pulp is treated with an esterase formulation in combination with a metalion or cationic polymer to increase the stability or activity or both of esterase enzymes at
high temperature, or at extreme pH ranges of acidic and alkaline conditions. The
treatment by esterase together with metals ion or cationic polymer can be used to treatpitch containing pulp at high temperatures prior to, during or after refining of woodchip/pulp, in order to enhance the reduction of pitch problems and facilitate in themanufacture of paper.
