Applications: Accurate on-line induction point recognition and feed-back loop activation
Cytoprom process monitoring systems allow accurate induction of expression systems without the need to take samples for off-line analysis, which would increase the risk of contamination. Growth data is always live, so an optimal induction condition will never need to be missed. Figure 1 shows how a continuous growth curve can be used to induce a process at the optimum cell concentration, an OD600 of 0.8 in this example. The system allows out-of- working hours induction, optimising the effective use of fermentation facilities.
Cytoprom can also provide an analogue output module for its USB spectrometers. The output modules can be added to provide a standard 4-20 mA output signal of spectrometer data, and can be used to present your optical data as a controller input for automated process control. A typical feedback loop is shown in Figure 2.
