Physiological data derived from steady-state chemostat cultures of engineered l-arabinose-metabolizing S. cerevisiae strains

	IMX929 (GAL2)	IMX1508 (PcaraT)
Residual l-arabinose (g L−1)	1.77 ± 0.19	0.004 ± 0.002
YX/S [g biomass (g l-arabinose)−1]	0.48 ± 0.06	0.40 ± 0.01
ql-arabinose (mmol g−1 h−1)	0.70 ± 0.10	0.80 ± 0.08

Strains expressing either GAL2 (IMX929) or PcaraT (IMX1508) as the sole functional l-arabinose transporter were grown in aerobic, l-arabinose-limited chemostat cultures (7.5 g L⁻¹ l-arabinose, dilution rate = 0.05 h⁻¹, pH 5, T = 30 °C). Data are derived from independent triplicate experiments and presented as average ± mean deviation
