Fig 3. Sensitivity of ethanol production on the PhPP of S. cerevisiae.

${\lambda }_{ARC}^{etoh}$: Sensitivity of q_etoh to the Available Reducing Capacity (ARC). Planes are colored according to ${\lambda }_{ARC}^{etoh}$ value, indicating if ARC is limiting (${\lambda }_{ARC}^{etoh}<0$), is in excess (${\lambda }_{ARC}^{etoh}>0$) or it has no effect on q_etoh. (a) showing the PhPP for specific growth rate (μ). (b) showing PhPP for specific ethanol productivity (q_etoh).
