Relationship between seven metabolic and life-history traits and individual isoforms of the enzymes involved in alcoholic fermentation. The best model accounting for trait variation was established using stepwise multiple regression (see equations in supplemental Information - text file). All the isoforms included in the model are presented. A, Percentage of variance of the CO₂ specific flux per cell accounted for by each isoform. B, Percentage of variance accounted for by each isoform for the concentration of ethanol, glycerol, and acetate per cell, and for biomass per cell. C, Percentage of variance accounted for by each isoform for two life-history traits: K (carrying capacity) and cell size.
