  • Patent number: 6607902
    Abstract: A variant of a cell-wall degrading enzyme having a beta-helix structure, which variant holds at least one substituent in a position determined by identifying all residues potentially belonging to a stack; characterising the stack as interior or exterior; characterising the stack as polar, hydrophobic or aromatic/heteroaromatic based on the dominating characteristics of the parent or wild-type enzyme stack residues and/or its orientation relative to the beta-helix (interior or exterior); optimizing all stack positions of a stack either to hydrophobic aliphatic amino acids, hydrophobic aromatic or polar amino acids by allowing mutations within one or all positions to amino acids belonging to one of these groups; measuring thermostability of the variants by DSC or an application-related assay such as a Pad-Steam application test; and selecting the stabilized variants. Variant of a wild-type parent pectate lyase (EC 4.2.2.

  • Publication number: 20030119172
    Abstract: Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase. The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N NaOH at 55° C. for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25° C.).

  • Patent number: 6265191
    Abstract: Lipase is immobilized on surfaces to facilitate oil removal from the surfaces and to alter wettability of the surfaces. The lipase is isolatable from a Pseudomonas organism such as Pseudomonas putida ATCC 53552 or from an organism expressing a coding region found in or cloned from the Pseudomonas. A particularly preferred lipase has a molecular weight of about 30 to 35 kd and is resolvable as a single band by SDS gel electrophoresis. Lipase sorbed on fabric forms a fabric-lipase complex for oil stain removal. The lipase may be sorbed on fabric before or after an oil stain, and the lipase is active to hydrolyze an oil stain on dry fabric or fabric in laundering solutions. The sorbed lipase has enhanced stability to denaturation by surfactants and to heat deactivation, is resistant to removal from fabric during laundering, retains substantial activity after drying fabric at an elevated temperature, and retains activity during fabric storage or wear.

    Abstract: During the desizing and enzymatic stonewashing of denim fabric and/or garments, redeposition of blue color often occurs back onto the surfaces of the denim. The invention relates to a redepositing or backstain inhibiting composition and a method requiring the inclusion of an added protease prior to, during or subsequent to the stonewashing process which reduces the redeposition of the blue dye and hence improves the stonewashing process when using redepositing or backstaining cellulases to give an appearance closer to that when using stones alone or nonredepositing cellulases in the stonewashing process.

  • Patent number: 6146858
    Abstract: Samples of commercial cellulose having high crystallinity (>80%) and a degree of polymerization of approximately 1500 were pretreated enzymatically under various conditions with commercial endoglucanases, before the chemical conversion to substituted cellulose derivatives was carried out. The enzymatically pretreated cellulose samples exhibited a significantly higher substitution, up to 222% higher, in comparison with control samples which had been treated with buffer without enzyme. The increase in substitution during the chemical reaction could be observed in the presence of various amounts of alkali, but fell as the amounts of alkali decreased. At the same degree of substitution of the cellulose derivative, the use of cellulose pretreated with endoglucanase significantly reduced the amount of alkali required by 60%, as compared with the use of cellulose pretreated only with buffer.

  • Patent number: 6140109
    Abstract: A method of treating wool, wool fibers or animal hair with a haloperoxidase (together with a hydrogen peroxide source and a halide source), and a proteolytic enzyme. The described method results in improved shrink-resistance, handle, appearance, wettability, reduction of felting tendency, increased whiteness, reduction of pilling, improved softness, tensile strength retention, improved stretch, improved burst strength, and improved dyeing characteristics such as dye uptake and dye washfastness. Furthermore, relative to treatments with proteolytic enzymes alone (no haloperoxidase), the described method results in reduced weight loss, reduced fiber damage, and improved burst strength.
