ABSTRACT:
A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed including a protease enzyme, a source of hydrogen peroxide and an ester substrate having the general structure ##STR1## where R and R' are alkyl groups unsubstituted or substituted with at least one functional group. Preferred substrates are defined which are preferably chemically non-perhydrolyzable. Processes for bleaching and peracid production are also disclosed.
