文摘

The results of a study of the temperature dependence of laser-induced fluorescence for four marine microalgae cultures that belonging to different taxonomic groups are described. The fluorescent properties of microalgae that were exposed to temperature stress up to irreversible changes in their cells have been examined. A comparative analysis has been performed and the models for the dependence of laser-induced fluorescence intensity on the temperature for the microalgal cell pigments have been constructed. The microalgae differ in both their dependence of fluorescence intensity on the thermal stress factor and the stress temperature value, which suggests that these characteristics are species specific.Keywordsmicroalgaephytoplanktonlaser-induced fluorescencethermal stress factor
