Estimating the term…
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.
A process for the production of a storage-stable material capable of degrading a waste product comprising at least one of phosphate esters and acrylonitrile, comprising cultivating a mixed culture of microorganisms capable of growing on the waste product by feeding in the waste product at a progressively increasing concentration which does not kill the microorganisms due to by-product formation, terminating the cultivation when the waste product-splitting activity of the culture has leveled off, separating at least a portion of the now active mixed culture and repeating the cultivation at least once to produce a stabilized active mixed culture, treating the stabilized active mixed culture chemically, and then drying to obtain a storage-stable active mixed culture.
A biologically pure culture of Pseudomonas strain DSM 1192 or 1193, said culture being capable of forming a stabilized mixed culture capable of degrading products of industrial organic syntheses.
