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 macro-nutrients as a sterile aqueous solution, preferably containing iron as ferric citrate. A preferred yeast is Candida utilis.

Abstract: IMPROVED APPARATUS FOR AEROBIC FERMENTATION Improved apparatus for the continuous aseptic growth of single-cell protein materials, employing an aqueous ethanolic substrate fortified with nutrient elements, preferably under oxygen limited conditions. The fermentation is conducted under conditions which afford effective means of attaining high rates of oxygen transfer and heat removal coupled with intense agitation.
