Development of enzymes to enhance laundry detergent product performance

该项目旨在将新类别的酶引入家用清洁产品中，以提高污渍去除性能。用酶改善洗衣洗涤剂的去污性能，不仅可以提高消费者的满意度，还可以减少相关的环境负担。酶可以取代更多的有毒成分；减少衣物重新洗的需要；并通过短的冷洗周期实现高标准的清洁。该项目将专注于新型氧化还原酶和多糖降解酶的开发和应用，这些酶解决了目前酶没有靶向的底物和污渍。目前洗衣粉中的漂白技术是基于过硼酸盐和过碳酸盐，这些技术不能并入液体洗涤剂中，在低温下不能有效地工作，并有助于水生富营养化。氧化还原酶为漂白污渍提供了一种酶制剂。类胡萝卜素污渍，如番茄酱和意大利面酱，是高发污渍，目前的洗涤剂仍然没有很好地去除这些污渍。该项目将鉴定和鉴定能够有效漂白类胡萝卜素污渍的新型类胡萝卜素降解酶。多糖类天然存在于食品中，也用作个人护理和食品产品的添加剂，它们是粘性物质，可以增加土壤对织物和陶瓷的粘附性。通过测定与土壤粘附性有关的特定多糖，可以识别针对这些坚韧污渍的酶，并将其应用于洗衣粉，从而更有效地去除污渍。这些多糖降解酶的性能将被基于分子探针的新方法所跟踪。

The project aims to introduce new classes of enzymes in household cleaning products to improve the stain removal performance. Improving the stain removal performance of laundry and dishwashing detergents with enzymes will not only improve consumer satisfaction, but will also decrease the associated environmental burden. Enzymes can replace more toxic ingredients; reduce the need for clothes to be rewashed; and achieve high standards of cleaning using short, cold washing cycles. The project will focus on the development and the application of novel oxidoreductases and polysaccharide-degrading enzymes, which address substrates and stains not currently targeted by enzymes.Current bleaching technology in laundry detergent is based on perborate and percarbonate, these technologies cannot be incorporated into liquid laundry detergent, do not work efficiently at low temperatures, and contribute to aquatic eutrophication. Oxidoreductase enzymes offer an enzymatic solution to bleaching stains. Carotenoid stains, such as tomato ketchup and spaghetti sauce, are high incidence stains that are still not well removed by today's current detergents. This project will identify and characterise novel carotenoid degrading enzymes that can efficiently bleach carotenoid stains.Polysaccharides are naturally present in food and also used as additives in personal care and food products, they are sticky substances that increase soil adhesion to fabrics and ceramics. By determining the specific polysaccharides implicated in soil adhesion, enzymes that target these tough stains can be identified and applied to laundry detergents, leading to more efficient stain removal. The performance of these polysaccharide degrading enzymes will be followed by novel methodologies based on molecular probes.
