3.2. Yields on substrate of the main fermentation metabolites
A low RQ value was expected to be a positive indication of the strain
potential for the reduction of ethanol content in wine by the previously
proposed strategy (Gonzalez et al., 2013). Yields of ethanol (YE/S) and
other fermentation metabolites on glucose were determined by growing
the different yeast strains in synthetic must (Table 2). In order to
give an indication of the performance of each strain for growth in synthetic
must, data on global sugar consumption after four days have
also been included in Table 2.
A positive correlation was indeed found for RQ and ethanol yield. It
was weak, but statistically significant (correlation coefficient 0.470;
Table 3 and Fig. S2). Other parameters, like acetic acid yield or global
sugar consumption, were also positively correlated to RQ and ethanol
yield, whilst glycerol and biomass yields were negatively correlated to
