Summary
Maintenance of active strains of microorganisms is one of the fundamental problems for every successful industrial biosynthesis. In this paper, the efficiency of lyophilization for long-term preservation of nonsporulating strains of the fungusClaviceps, producing ergot alkaloids in saprophytic cultures, was studied. It was found that lyophilization is a suitable method for the preservation of the testedClaviceps strains. All treated strains have retained their vitality and biochemical properties unchanged after three years of storage.
