The preparation of an activity-stable and low-dust enzyme granulate for washing and cleaning applications, e.g. for use in granular washing and cleaning agent compositions, is described. Also described are the activity-stable and low-dust enzyme granulates obtained in accordance with the method of preparation as well as their use in washing and cleaning applications. In addition, in a special aspect of the invention, the use of specially selected flours as auxiliary agents for the preparation of enzyme granulates for diverse application purposes is described.

Enzyme granulate for washing and cleaning

New enzyme granulates are described which contain an organic disulfide compound (R&mdash;S&mdash;S&mdash;R), particularly they contain the free amino acid cystine, optionally mixed with the amino acid cysteine. The new enzyme granulates are for us in detergent and cleanser compositions, particularly in dishwasher compositions, and they have properties. For example, insofar as protecting objects made of silver against tarnishing, for example, dishes, cutlery, and other objects to be cleaned.

The invention relates to a novel high-alkaline protease, its use in the industrial or domestic fields and also compositions for said uses containing this protease. The protease of the invention is a selected triple mutant derived from certain precursor proteases from the subtilisin group, especially of the &ldquo;subtilisin 309&rdquo; type.
