A new commercial strain of ergot adapted from a wild grass

A strain of CLAVICEPS PURPUREA (F R.) T UL. isolated from ARTHRAXON LANCIFOLIUS H OCHST. was successfully adapted on rye. Experimental cultivation on rye showed 370 kg/ha yield of sclerotia containing 0.5% total alkaloid which consisted of 33% ergometrine, 17.6% ergotamine, 18.7% ergocornine and 22.7% ergokryptine. The results also reveal that alkaloid profile of the ergot strain depends largely on its host. Significantly high yield of the sclerotia and the valuable alkaloid profile of the new strain indicate its commercial potential.
