Abstract

A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed, including: (a) a protease enzyme; (b) an ester substrate having the structure


R ′(Z) (CH₂)- -O-R,
wherein R = C₁₋₁₁-alkyl, R′ = C₁₋₁₀-alkyl or H,
Z = O or
a polyalkoxy residue of the formula (CH₂CH₂O)m or wherein m = 0-10,
r = 0 or 1;
R and R′ optionally having OH-substituents pendant on or terminating the hydrocarbyl chains, and (c) a source of peroxygen capable of reacting with the protease (a) and the ester substrate (b) to result in proteolytic production of of peracid.
