Acta Botanica Croatica, Vol.53 No.1 December 1994. -

The effect of several surfactans i. e. commercial antifoams on biosynthesis of ergot alkaloids was studied. Addition of some surfactants of polyglvcole structure and Tweens to submerged cultures of high-productive strain of C. paspali F-2057 caused a change in alkaloid synthesis intensity. Pluronik polyetoxypolypropoxy polymer added in the range of 0.25 to 0.75% markedly stimulated the production of ergot alkaloids. The Pluronik-supplemented culture reached maximal alkaloid yields one or two days earlier than the control. Production of alkaloids increased twice. The maximal yield achieved was 5.35 gL -1 with the process productivity amounting to 17.2 mgL-1h-1.
