[Optimization of conditions for storage and cultivation of the fungus Claviceps sp.--a producer of the ergot alkaloid agroclavine].


PMID 12754833

Abstract

Conditions of agroclavine biosynthesis by the mutant Claviceps sp. strain s 106 were studied. The content of agroclavine was maximum (1.5-2 g/l) on days 15-16 of cultivation in the complex medium T25, containing sucrose, citric acid, and yeast extract. Agroclavine was the major component of the alkaloid fraction (90-95%). Storage of the culture at -70 degrees C in T25 supplemented by 7% glycerol provided a stable level of alkaloid formation.
