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.
Abstract translation: 通过改进的好氧发酵方法无菌生长酵母，使用强化营养元素的乙醇水溶液，优选在受限氧条件下。 发酵在连续的方式在保持在超大气压的区域内进行。 将微营养物作为无菌水溶液与大量营养素分开加入到底物中，优选含铁作为柠檬酸铁。 优选的酵母是产朊假丝酵母。

Abstract: Protein-containing single-cell microorganisms are texturized by extruding an aqueous cellular paste containing at least some ruptured cells and further conditioning the fibrous extrudate by combination of heating and drying. The texturized product is suitable for use as a food product or as a protein-rich additive for food products.
