摘要： Methods for reducing energy required for a pulp refining processes by treating a mechanical pulp with a hemicellulase composition are presented. The enzymatic treatment can be carried out at a temperature of from about 10° C. to about 90° C., and/or at a pH of from about 2 to about 10. Paper made from the treated pulp has improved strength over paper made from untreated pulp.

摘要： The present invention relates to a method for preventing or reducing deposits in pulp and paper making processes by including a cyclodextrin during or after pulp formation in an amount effective for preventing or reducing the deposits. Optionally the cyclodextrin comprising the deposit is subsequently separated from the pulp.
