Figure 6From: The metabolic costs of improving ethanol yield by reducing glycerol formation capacity under anaerobic conditions in Saccharomyces cerevisiaeNADH balances for the S. cerevisiae wild-type and the two mutants TEFmut7 and TEFmut2. NADH balances were calculated for each strain when μmax was reached, respectively from the metabolic flux calculation. Left bars correspond to the generated NADH not balanced by ethanol formation and by pyruvate formation; right bars correspond to the reoxidized NADH (by glycerol and succinate formation).Back to article page
