Abstract

Studies were undertaken on the production of ergot alkaloids in saprophytic culture employing two strains of C. purpurea. In an attempt to improve the yield of the alkaloids and to develop a cheaper medium, the commonly used carbohydrate source, mannitol, was replaced with different types of starches and starchy materials as these are comparatively much cheaper than mannitol. Results indicated that, in stationary cultures, certain starches enhanced the yield greatly, while in shaker cultures starches could replace mannitol for equivalent yields.
