Patent ID: 8148314

Claim:
A process for treating an article of clothing or a textile for bleaching, stain removal, odor reduction, sanitization or disinfection using an enzymatically-produced peroxycarboxylic acid composition, said process comprising: (a) providing a set of reaction components, said components comprising: (1) a formulation comprising a mixture of: (I) at least one carboxylic acid ester selected from the group consisting of monoacetin, diacetin, triacetin, monopropionin, dipropionin, tripropionin, monobutyrin, dibutyrin, tributyrin, and mixtures thereof; (II) an enzyme powder comprising (i) at least one enzyme structurally classified as a CE-7 enzyme and having perhydrolysis activity and a signature motif comprising: (A) an RGQ motif at amino acid residues 118-120, (B) a GXSQG motif at amino acid residues 179-183, and (C) an HE motif at amino acid residues 298-299 when aligned to reference sequence SEQ ID NO:1 using CLUSTALW, (ii) at least one excipient, and (iii) optionally at least one surfactant; and III) at least one buffer; wherein said at least one buffer enhances the stability of said at least one enzyme when present in said formulation as compared to the perhydrolase activity of said at least one enzyme when the at least one excipient is not present; and (2) a source of peroxygen; (b) combining said reaction components under suitable aqueous reaction conditions whereby a peroxycarboxylic acid product is formed; (c) optionally diluting said peroxycarboxylic acid product; and (d) contacting said article of clothing or textile with the peroxycarboxylic acid produced in step (b) or step (c); wherein said article of clothing or textile is cleaned, destained, deodorized, sanitized, disinfected, or a combination thereof.
