     a biochemically structured model has been developed to describe the continuous fermentation of lactose to ethanol by kluveromyces marxianus and allowed metabolic coefficients to be determined. anaerobic lactose-limited chemostat fermentations at different dilution rates (0.02–0.35 h−1) were performed. species specific rates of consumption/formation, as well as yield coefficients were determined. ethanol yield (0.655 c-mol ethanolc-mol lactose−1) was as high as 98% of theoretical. the modeling procedure allowed calculation of maintenance coefficients for lactose consumption and ethanol production of ms = 0.6029 and me = 0.4218 (c-mol) and (c-mol h)−1, respectively. true yield coefficients for biomass, ethanol and glycerol production were calculated to be ytruesx = 0.114, ytrueex = 0.192 and ysg = 2.250 (c-mol) and (c-mol)−1, respectively. model calculated maintenance and true yield coefficients agreed very closely with those determined by regressions of the experimental data. the model developed provides a solid basis for the rational design of optimised fermentation of cheese whey.
