Abstract

A process for the production of a storage-stable preparation of micro-organisms, starting from a mixed culture of micro-organisms, which is capable to degrade products of industrial organic syntheses, which comprises that the culture conditions of an active mixed culture enriched in the customary manner are optimized, with the addition of the product to be degraded, in the customary manner according to the rate of degradation of the product and this mixed culture is converted in at least two passes into a stabilized activated mixed culture under the optimum conditions thus determined, and the culture thereby obtained is rendered storage-stable, its activity being maintained.
