A process is provided to produce a concentrated aqueous peracid solution in situ using at least one enzyme having perhydrolase activity in the presence of hydrogen peroxide (at a concentration of at least 500 mM) under neutral to acidic reaction conditions from suitable carboxylic acid esters (including glycerides) and/or amides substrates. The concentrated peracid solution produced is sufficient for use in a variety of disinfection and/or bleaching applications.

A process is provided for producing peroxycarboxylic acids from carboxylic acid esters. More specifically, carboxylic acid esters are reacted with an inorganic peroxide, such as hydrogen peroxide, in the presence of an enzyme catalyst having perhydrolysis activity. The present perhydrolase catalysts are classified as members of the carbohydrate esterase family 7 (CE-7) based on the conserved structural features. Further, disinfectant formulations comprising the peracids produced by the processes described herein are provided.
An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a
Thermotoga maritime
acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in the ratio of peracetic acid formation to peracetic acid hydrolysis specific activities (PAAF/PAAH ratio). The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.
