Patent ID: 7780911

Claim:
A biocidal composition comprising components suitable for producing peracid in situ, wherein said components comprise: (a) one or more prion-degrading enzymes, (b) a suitable substrate selected from the group consisting of: (i) esters having the structure wherein R 1 =C1 to C10 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 2 =C1 to C10 straight chain or branched chain alkyl group, (CH 2 CH 2 —O) n H or (CH 2 CH(CH 3 )—O) n H and n=1 to 10; (ii) glycerides having the structure wherein R 1 =C1 to C10 straight chain or branched chain alkyl optionally substituted with an hydroxyl or a C1 to C4 alkoxy group and R 3 and R 4 are individually H or R 1 C(O); and (iii) amides having the structure wherein R 5 and R 6 are individually H, acetyl, or a C1 to C5 straight chain or branched alkyl group, (c) at least one enzyme having perhydrolase activity, and (d) a source of peroxygen.
