Description

The optionally present enzyme is preferably a protease, amylase, lipase, cellulase, hemicellulase, oxidase, peroxidase or mixtures thereof. The enzymes mainly used are proteases obtained from microorganisms such as bacteria or fungi. Proteases are suitable in known procedures according to fermentation methods described, for example, in German published patent publications DE 1940488, DE 2044161, DE 2101803 and DE 2121397, US Pat. No. 3,623,957 and US Pat. Obtained from microorganisms. Proteases are commercially available, for example under the trade names BLAP ™, Savinase ™, Esperase ™, Maxatase ™, Optimase ™, Alcalase ™, Durazym ™ or Maxapem ™. ing. Lipases that can be used are, for example, Humicola lanuginosa described in European patent applications EP 258068, EP 305216 and EP 341947, Bacillus species described in international patent application WO 91/16422 or European patent application EP 384177, European patent applications EP 468102, EP 385401, EP 375102, EP 334462, Pseudomonas species described in EP331376, EP330641, EP214761, EP218272 or EP204284 or international patent application WO90 / 10695, for example Fusarium species described in European patent application EP130064, for example Rhizopus species described in European patent application EP117553 or European patent application Obtained from the Aspergillus species described in EP167309. Suitable lipases include Lipolase ™, Lipozym ™, Lipomax ™, Lipex ™, Amano ™ lipase, Toyo-Jozo ™ lipase, Meito ™ lipase and Diosynth ™ lipase. It is marketed with the brand name. Suitable amylases are commercially available, for example, under the trade names Maxamyl ™, Termamyl ™, Duramyl ™ and Purafect ™ OxAm. Cellulases that can be used will be enzymes obtained from bacteria or fungi having an optimum pH value, preferably in the weakly acidic to weakly alkaline range of 6 to 9.5. Such cellulases are known, for example, from German published patent publications DE 3117250, DE 3207825, DE 3207847, DE 3322950 or European patent applications EP 265632, EP 269777, EP 270974, EP 273125 and EP 339550, and international patent applications WO 95/02675 and WO 97/14804, Celluzyme ( (Trademark), Carezyme (trademark) and Ecostone (trademark).
