Abstract:
A storage-stable liquid laccase formulation comprising(i) a laccase derived from Polyporus and(ii) at least one polyalcohol at a concentration from about 5 to about 75% of said formulations;wherein said formulation has a pH at least between about 1 and 5 pH units more alkaline than the pH optimum of the laccase, when said pH optimum is measured using syringaldazine as a substrate; andwherein storage of the formulation for 14 days at 40.degree. C. results in maintenance of at least 30% of the enzymatic activity of the laccase in said formulation as compared with the enzymatic activity of the laccase in an identical formulation stored for 14 days at 4.degree.
