Abstract
The invention relates to a new process for the preparation of ergot alkaloids, primarily ergocornine and .beta.-ergocryptine, by subjecting a Claviceps purpurea strain to fermentation under aerobic conditions in a culture medium which contains carbon and nitrogen sources, mineral salts and optionally other additives, too. According to the invention a Claviceps purpurea variant strain deposited under No. MNG 00186 is applied as alkaloid-producing strain.
