BIOENERGETIC APPROACH TO ETHANOL-LIMITED CULTURE OF SACCHAROMYCES CEREVISIAE

Abstract

Kinetic equations dealing with rates of substrate consumption, cell growth, respiration, product formation and heat evolution have been derived for Saccharonzyces cerevisiae growing on ethanol as the sole carbonaceous material. These equations which could all be shown as functions of ethanol and dissolved oxygen concentrations will be of help to simplify the approach from microbial kinetics to an attempt of optimization in the fermentation industry.
