Abstract
Studies have been made of the growth of three yeasts Candida krusei, Saccharomyces chevalierie and Saccharomyces rouxii on olive mill wastewater (OMW). The cultures were made in a shaker flask culture and in a fermentor in order to select organisms which can produce large quantities of biomass. Three yeasts have been selected that will tolerate the polyphenols. They can be used to reduce Biological Oxygen Demand (BOD) (40–50%), and perhaps become a source of Single Cell Protein (SCP) for supplementation of animal feeds. Concentration of protein of 3.35 g 1‐1 and yield of 0.45g of biomass per g of glucose based on glucose consumption were obtained using Saccharomyces rouxii strain.
