Addition of a water-soluble polyelectrolyte (i.e. an anionic or cationic polymer) significantly increases the hydrolysis rate of esters in the presence of lipases. The invention provides a process for hydrolysis of water-insoluble ester in the presence of a lipase characterized by the presence of a water-soluble polyelectrolyte. The invention also provides a method of increasing the rate of hydrolysis of water-insoluble ester in the presence of a lipase by incorporation of a water-soluble polyelectrolyte.

A process for hydrolysis of water-insoluble esters in the presence of a lipase, at a pH in the range of 3-7 particularly to such a process for hydrolysis of resin in pulp.

Method of making paper from pulp treated with lipase and an aluminum salt
