The production of the main metabolites was also and as
expected linked to growth, since both ethanol and glycerol
productions were observed for the three yeasts for a sugar
content of 174.0 ± 0.2 kg m3 in the culture medium (Table 1);
while in the presence of 358.0 ± 1.0 kgm3 sugar content in the
medium, metabolites production was only observed for Z.
rouxii. It should be observed that the highest ethanol production
was observed for S. cerevisiae (Table 1), in agreement with
