The production of single‐cell protein (SCP) from ethanol by different imcroorganisms is briefly reviewed. The trends in modeling the SCP production are outlined with a stress on the need to incorporate metabolic and engineering considerations into the pertinent models. Data on batch yeast growth on ethanol are analyzed, a metabolic model involving design parameters is suggested, parameters values are estimated, and their significance is discussed. The model essentially describes the response of a system to disturbances (substrate, metabolites, oxygen, etc.). An effective numerical integration procedure is necessary in the solution of the model which has “stiff” character.
