Methodology of Measuring and Using Fluorescent Parameters of Microalgae

Abstract

The increasing frequency of harmful algal blooms and the growth of associated losses create a need to study and develop new methods for express monitoring of water areas. Using the optical signal of fluorescent algae can be used to track their concentration. By changing environmental conditions, it is possible to control fluorescence spectra to obtain fluorescence parameters that allow distinguishing microalgae from each other by the optical signal. The article demonstrates a technique for measuring fluorescence parameters and shows their characteristic differences from each other. The dynamics of fluorescence during heating at different rates is studied, where lower rates allow achieving less dispersion of fluorescent signals arising during the destruction of algae cells.
