Figure 2From: Differentiation between two strains of microalga Parachlorella kessleri using modern spectroscopic methodFluorescence spectra. (А) under excitation at 430 nm (В) at 720 nm in wildtype (curve 1) and mutant strains Parachlorella kessleri cells (PCMut2- curve 2) and (PCMut4 -curve 3). Fluorescence spectra are normalized to the maximum fluorescence values at 690 nm. Fluorescence excitation spectra are normalized to corresponding values of the red absorption maximum at 680 nm.Back to article page
