ABSTRACT:
Yeast is produced by fermenting hydrocarbons in an aqueous nutrient medium which includes sulfate, chloride and phosphate ions. When the fermentation is completed the nutrient medium has become depleted in mineral content and a large portion of it is purged. A calcium source is added to precipitate the phosphate ion out as calcium phosphate. The precipitated calcium phosphate is added to the yeast, which in itself is an excellent source of protein. The resulting product is suitable for use as an enriched animal feed. Meanwhile the removal of the phosphate ion eliminates a pollutant from the purge stream.
