Wild-type (WT) and XI transformants growth in minimal-media containing glucose with and without xylose. Glucose consumption (a) and biomass accumulation (b) in media containing glucose alone. Consumption of glucose (c) and xylose (d), xylitol production by day 7 (e), and biomass accumulation (f) in media containing glucose and xylose. The experiments were done in triplicate. Error bars represent standard deviations. Symbols: diamonds, wild type; squares, XI 4; triangles, XI 6; hexagons, XI 8; and circles, XI 16
