Culture profiles during the control fed-batch culture with methanol as sole carbon source, as shown by the shadowed zone. (A) Time courses of biomass, substrates, dilution rate, and β-galactosidase activities; (B) Time courses of biomass, substrates, dilution rate, and β-galactosidase activities during the control fed-batch culture with mixed feed (methanol fraction 0.60 C-mol/C-mol), as shown by the shadowed zone.
