ABSTRACT:
A process is provided to improve the specific activity of an enzyme catalyst having nitrilase activity when converting glycolonitrile to glycolic acid under aqueous reaction conditions. Inclusion of an effective amount of at least one amine protectant improves the specific activity and catalytic productivity of the enzyme catalyst.
