Title:
【発明の名称】リパーゼ-触媒化エステル加水分解
Document Type and Number:
Japanese Patent JP3103113
Kind Code:
B2
Abstract:
The invention provides a process for hydrolysis of water-insoluble ester in the presence of a lipase derived from a strain of Humicola, Candida antarctica, Pseudomonas, Chromobacterium or Aspergillus at pH 3-7, characterized by the presence of an aluminium salt, and particularly to such a process for hydrolysis of resin in pulp. It also provides a method of increasing the rate of hydrolysis of water-insoluble ester in the presence of such a lipase, by incorporation of an aluminium salt. Addition of aluminium salt significantly increases the hydrolysis rate of esters in the presence of the above lipases. A strong increase of fat hydrolysis (from c. 50 % to c. 87 % hydrolysis) was found with as little as 10 mu M Al<+++>.
