## Abstract This work presents a multi‐route, non‐structural kinetic model for interpretation of ethanol fermentation of lactose using a recombinant flocculent __Saccharomyces cerevisiae__ strain expressing both the __LAC4__ (coding for __β__‐galactosidase) and __LAC12__ (coding for lactose permeas
Recombinant Saccharomyces cerevisiae TMB3001, harboring the Pichia stipitis genes XYL1 and XYL2 (xylose reductase and xylitol dehydrogenase, respectively) and the endogenous XKS1(xylulokinase), can convert xylose to ethanol. About 30% of the consumed xylose, however, is excreted as xylitol. Enhanced
