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 m_3 in the
culture medium (Table 1); while in the presence of 358.0 ± 1.0 kgm_3 sugar content in the medium,
metabolites production was only observed for Z.rouxii .
