    摘要: The present invention provides variants of a parent cellulase, such as, e.g., a cellulase classified in family 45 such as a Humicola insolens 43 kD endoglucanase, comprising a cellulose binding domain (CBD), a catalytically active domain (CAD), and a region linking the CBD and CAD (the linking region), wherein one or more amino acid residues of the CBD, CAD, or linking region is deleted or substituted by one or more amino acid residues and/or one or more amino acids are added to the linking region and/or another CBD is added at the opposite end of the CAD. Such variants have improved properties as regards, e.g., alkaline activity, compatibility with detergent composition ingredients, particular soil removal, color clarification, defuzzing, depilling, harshness reduction, and sensitivity to anionic surfactants. Such variants are useful, e.g., in detergent compositions, for textile treatment, in paper pulp processing, for animal feed, and for stone-washing of jeans.

    摘要: A method for lowering the extractable protein content in a natural rubber latex to below 30 parts per million (ppm) comprises the steps of treating by washing a rubber article, such as a rubber glove, with an aqueous solution containing a soluble silicate and, optionally, a protease. The methods claimed effectively reduce the allergenicity of the articles so treated.
