    • The present invention provides a detergent composition comprising a quaternary ammonium compound of formula: R.sub.1 R.sub.2 R.sub.3 R.sub.4 N.sup.+ X.sup.-,wherein R.sub.1 is C.sub.8 -C.sub.16 alkyl, each of R.sub.2, R.sub.3 and R.sub.4 is independently C.sub.1 -C.sub.4 alkyl or hydroxy alkyl, benzyl or --(C.sub.2 H.sub.40).sub.x H where x has a value from 2 to 5, not more of R.sub.2, R.sub.3 or R.sub.4 being benzyl, and X is an anion, and a cellulase characterized in that said cellulase provides at least 10% removal of immobilized radio-active labelled carboxymethylcellulose according to the CMC-method at 25.times.10.sup.-6 % by weight of cellulase protein in the laundry test solution. According to the present invention, a preferred cellulase consists of a homogeneous endoglucanase component which is immunoreactive with a monoclonal antibody raised against a partially purified=43 kD cellulase derived from Humicola insolens DM 1800.
    • 本发明提供一种洗涤剂组合物,其包含式R 1 R 2 R 3 R 4 N + X - 的季铵化合物,其中R 1为C 8 -C 16烷基,R 2,R 3和R 4各自独立地为C 1 -C 4烷基或羟基烷基,苄基或 - (C 2 H 40 )xH,其中x具有2至5的值,不多于R 2,R 3或R 4为苄基,X为阴离子,纤维素酶的特征在于所述纤维素酶提供至少10%的固定化的放射性活性标记的羧甲基纤维素 根据CMC-方法在洗衣试验溶液中的25×10 -6重量%的纤维素酶蛋白质。 根据本发明,优选的纤维素酶由与源自Humicola insolens DM 1800的部分纯化的= 43kD纤维素酶产生的单克隆抗体免疫反应的均匀内切葡聚糖酶组分组成。
