PGM2 overexpression improves anaerobic galactose fermentation in Saccharomyces cerevisiae

Table 3 Parameters analyzed during anaerobic batch fermentation of galactose.

Strain	Maximum specific growth rate μ_max (h^-1) ^a	Biomass yield (g g galactose ^-1)	Glycerol yield (g g galactose^-1)	Ethanol yield (g g galactose ^-1)	Fermentation time (h)
Control i	0.098 ± 0.003	0.08 ± 0.00	0.07 ± 0.01	0.41 ±0.02	69.3 ± 0.8
PGM2 i	0.139 ± 0.004	0.09 ± 0.01	0.09 ± 0.01	0.41 ± 0.02	45.5 ± 0.4

^aMaximum specific growth rate was calculated by linear regression of a logarithmic plot on the phase of constant and maximum values.
