The present invention is directed to an improved method of processing thin stillage from ethanol production and/or other industrial processes to produce high value fungal biomass that can be recovered by simple means. The effluent is sanitized and recycled using a novel disinfection technique. This innovative approach generates revenue from low value thin stillage, while reducing wastewater purification costs.
