Abstract

In the production of griseofulvin by the submerged aerobic culture of a griseofulvinproducing organism in a nutrient therefor, the medium contains assimilable nitrogen at a level of more than 0,3% (calculated as N), and a nutrient carbohydrate serving to supply carbon and energy requirements of the organism is repeatedly added to the medium during the course of the culture in such quantities and at such times that the pH of the medium follows a controlled pH curve as defined in Specification 868,958. Specifications 784,618, 934,526 and 934,528 also are referred to.
