  • Method for controlling the amount and distribution of alkaloids formed in a fermentation process
    Patent number: 4390625
    Abstract: The invention relates to a new method for controlling the level and distribution of alkaloids produced by Claviceps purpurea variant strains capable of producing primarily ergocornine, .alpha.-ergocryptine and .beta.-ergocryptine under saprophytic conditions. According to the invention a compound of the biosynthesis path of isoleucine or a compound which promotes the formation of isoleucine by biochemical control is added to the fermentation broth. In other respects fermentation is performed under conditions known per se.By the method of the invention the ratio of .alpha.- and .beta.-ergocryptine formed in the fermentation broth can be adjusted to the optimum value.
