Table 1.

Specific growth rate (μ) and specific glucose consumption rate (Q_Glc) in CCO cultures treated with different concentrations of ammonium-chloride or sodium lactate. Specific lactate production rate (Q_Lac) was determined for lactate treated cells only

Ammonium/Lactate concentration (mM)	Ammonium treated cells		Lactate treated cells
