TABLE 1.

Traits, units, and meaning of the measured variables. All species were grown at similar conditions (batch cultivation) of media and temperature (25ºC), and traits are presented in standardized units to biomass. Variables were measured at the moment of maximum growth rate. Extended and detailed methods, as well as the descriptive statistics of all the variables, are provided in the original reference (Hagman et al., 2013)

Variable	Abbrev	Units	Definition and meaning
Ethanol yield	EthY	g/g (grams produced per gram of glucose consumed)	Rate of ethanol production per unit of glucose consumed, a measure of fermentative performance
Respiratory quotient	RQ	Adimensional	Ratio between the CO2 produced and O2 consumed. The larger the fermentative capacity, the higher the RQ
Glycerol production	Gly	(g/gDW hr) grams produced, per gram of biomass, per hour	Rate of glycerol production, a by‐product of alcohol fermentation
Growth rate	DW	Dry weight growth rate	Rate of increase in dry weight, measured for 24 hr
