title: [Preservation of Claviceps purpurea, the producer of peptide ergot alkaloids, by the method of freeze drying].
abstract: A saprotrophic strain of Claviceps purpurea VNIIA 312A, an organism producing peptide +ergot alkaloids with prolactin inhibiting activity was shown to die under lyophilization conditions. To provide long-term storage of strain 312A, L-drying or drying under vacuum from liquid state was used with success. Three protective media were tested. Favourable results were obtained by using 25 per cent maltose solution as a protective medium. Preservation of the culture viability was accompanied by maintenance of the culture capacity for active formation of the biomass and production of +ergot alkaloids.
