Figure 1From: Scale-up from microtiter plate to laboratory fermenter: evaluation by online monitoring techniques of growth and protein expression in Escherichia coli and Hansenula polymorpha fermentationsComparison of the experimental set up. (A) Measurement principle of the microtiter plate fermentation in the BioLector via back scattering of light from cells and fluorescence emission of molecules; (B) Measurement principle of the stirred tank fermentation with online measurement of OD and fluorescence in the bypass.Back to article page
