Abstract: Described are compositions and methods for the decolorization of dye molecules in an aqueous medium using enzymatically-generated peracid.

Abstract: Variants of a Pseudomonas saccharophila G4-forming amylase (PS4) advantageously can catalyze high temperature saccharification to produce maltotetraose syrup from a starch liquefact or granular starch, e.g., derived from cornstarch. The PS4 variants are useful in a process of saccharification of starch that advantageously produces significant amounts of maltotetraose, which can be used downstream in a process of producing a maltotetraose syrup. In one embodiment, a thermostable PS4 variant is provided that can produce about 40% to about 60% by weight maltotetraose, based on total saccharide content.

Abstract: Described are compositions and methods for the enzymatic abrading and color modification of dyed textiles. The compositions and methods permit a textile manufacturer to obtain a wide variety of different textile finishes and colors using exclusively enzymatic methods.

Abstract: The combination of a Pseudomonas saccharophila G4-forming amylase (PS4) variant and a pullulanase advantageously can catalyze at a high temperature saccharification to produce an increased amount of maltotetraose, which can be used downstream in a process of producing a maltotetraose syrup. In one embodiment, a thermostable PS4 variant supplement with a pullulanase is provided that can produce about 40% to about 60% by weight maltotetraose, based on total saccharide content.

Abstract: A method for adjusting the colour tone of dyed cellulosic textile fibre material comprising contacting said textile material with an enzymatic textile treatment composition comprising (i) a perhydrolase enzyme, (ii) an ester substrate for said perhydrolase enzyme, and (iii) a hydrogen peroxide source, for a length of time and under conditions suitable to permit measurable brightening of the textile material.
