    • Variants of Lipolase3 (wild-type Humicola lanuginosa lipase) with a certain distribution of electrically charged amino acids have a particularly good first-wash performance in a detergent solution with a high ratio of anionic to non-ionic surfactant. The effect is achieved by attaching a positively charged peptide extension at the N-terminal and by imposing certain restrictions on the charge distribution in the region corresponding to amino acid positions 90-101 and at position 210. The inventors further devised a method of developing variants with such performance from Lipolase by attaching a peptide extension at the N-terminal and substituting amino acids in the region 90-101 or in the immediate surroundings in the three-dimensional structure. The lipases may further provide additional benefits, such as whiteness maintenance and dingy cleanup.
    • 具有一定分布的带电氨基酸的Lipolase3(野生型Humicola lanuginosa脂肪酶)的变体在具有高比例的阴离子与非离子表面活性剂的洗涤剂溶液中具有特别好的第一洗涤性能。 通过在N末端连接带正电荷的肽延伸和通过对对应于氨基酸位置90-101和位置210的区域中的电荷分布施加某些限制来实现该效果。本发明人进一步设计了开发变体的方法 通过在N末端附加肽延伸并且在90-101区域或在立体结构中的周围环境中代替氨基酸,从Lipolase获得这种性能。 脂肪酶可进一步提供额外的益处,例如白度维持和肮脏清洁。

    • The present invention relates to a composition for treating synthetic textile material and a method of using it. The composition comprises a smectite clay to scour the textile material, a wetting agent to enhance addition of the clay to other components of the composition, a sequestrant to sequester metal ions that inhibit the performance of the clay, and, when the composition is an aqueous slurry, a viscosity control agent to adjust the viscosity of the composition in order to prevent separating or settling of the clay. The method comprises contacting the textile material with the synthetic textile material treating composition under conditions sufficient to remove the contaminants from the textile material and washing the textile material treating composition off of the textile material, thereby producing a treated textile material from which the contaminants have been removed.
