Figure 1. Envelopes for ethanol production and growth rate.

(a): Envelope for S. stipitis. Glucose uptake rate of 4.45 mmol gDW⁻¹ h⁻¹ and unbounded oxygen uptake rate were considered. (b): Envelopes for S. cerevisiae. Glucose uptake rate of 14.08 mmol gDW⁻¹ h⁻¹ considering unbounded oxygen uptake rate (envelope 1), and an upper bound of 2.8 mmol gDW⁻¹ h⁻¹ (envelope 2). Arrows indicate data reported by Papini et al. [18].
