Some Claviceps strains producing clavine alkaloids were cultured in shaken flasks in two‐phase systems consisting of a water‐immiscible organic solvent, n ‐alkanes and an aqueous culture medium. Culture behaviour was different with light and heavy alkanes but no changes in the proportions of individual alkaloids were found. n ‐Octane caused a stimulation of sclerotia‐like growth and of specific biomass productivity. Increasing medium volumes in flasks brought about deterioration of aeration conditions and reduced production. Optimum fermentation results were restored by adding liquid paraffin to the culture. Heterogeneous systems of the above kinds appear to be suitable for optimization and scale‐up of clavine fermentation.
