The process includes filtering the substrate, inoculating the substrate with a yeast strain and fermenting it under yeast growth conditions in a bioreactor. The product of the bioreactor is then separated into a yeast cream and a centrate. A portion of the yeast cream is further processed to produce a substantially pure yeast product. The centrate is concentrated and combined with the remainder of the yeast cream to produce a yeast cream/centrate mixture. This mixture is further processed to produce a modified cultured yeast product. The combination of the yeast cream and the concentrated centrate produces a new product having potential for human and animal consumption. The further use of the centrate to produce a food supplement also reduces the amount of environmentally-undesirable waste discharge.
