Abstract: Yeasts are grown aseptically by an improved aerobic fermentation process, employing an aqueous ethanolic substrate fortified with nutrient elements, preferably under oxygen-limited conditions. Fermentation is effected in a continuous manner in a zone maintained under super-atmospheric pressure. Micro-nutrients are added to the substrate separately from macronutrients as a sterile aqueous solution, preferably containing iron as ferric citrate. A preferred yeast is Candida utilis.
