WebSep 21, 2024 · Absorption, fluorescence spectra of chlorophyll a (Chl-a) and all-trans-β-carotene (β-Car) mixing solution are investigated in different polarity and polarizability solvents. The carotenoids regulate the energy flow in photosynthesis by interaction with chlorophyll, leading to an observable reduction of Chl-a fluorescence. The fluorescence … WebApr 8, 2024 · For microalgal cell, the Raman spectroscopy has been used to detect their “product spectrum”.
