A process was developed for simultaneous utilization of several food wastes and production of single cell protein by successive growth of Bacillus subtilis and Lactobacillus acidophilus. A collagen‐derived substrate, starch, and cheese whey represented food wastes. Growth of B. subtilis on combined wastes yielded a biomass of 3.6 g/l and significantly modified the medium. Other bacilli also had similar potential for altering the original material. After fortification with cheese whey, the modified medium was used for growth of L. acidophilus as a second stage biomass production. Optimal growth conditions were determined. The feasibility of the process will be dependent upon increasing L. acidophilus biomass yields.
