As sessile organisms, plants cannot easily circumvent stressors by relocating. To evaluate the quality and quantity of abiotic and biotic stresses experienced, plants have evolved complex signaling pathways. Oftentimes molecules belonging to potential pathogens are recognized on the level of the plants’ plasma membrane. Upon recognition, the signal is relayed from the outside of the cell into the cell, ultimately inducing a defense reaction, if possible. In the Pathogen Triggered Immunity (PTI), a basal defense reaction, the signal is often transferred with the help of the secondary messenger Ca2+.

Why It Is Important to Measure Different Parameters Online in Shake Flasks

SFR vario Measures O2, OUR, pH and Biomass Online

Optical sensors enable monitoring and controlling important culture parameters even at shake flask scale. In this short report we show an example of multiparameter monitoring with SFR vario in S. cerevisiae culture, and how different sensors deliver most conclusive information in different culture phases.

Important Information for the Measurement of the Oxygen Uptake Rate OUR:

If your customers want to measure OUR, make sure that they also buy the oxygen module, as OUR measurement is only possible in combination with the oxygen module!
