Using Fluorescence Measurements to Model Key Phenomena in Microalgae Photosynthetic Mechanisms

Using Fluorescence Measurements to Model Key Phenomena in Microalgae Photosynthetic Mechanisms

Fluorescence is a powerful tool in characterizing the photosynthetic properties of microalgae. In this work we discuss a dynamic model able to accurately represent Pulse Amplitude Method (PAM) fluorescence data. The model includes photoproduction, photoinhibition and photoregulation and has been cal...
