Figure 5From: Differentiation between two strains of microalga Parachlorella kessleri using modern spectroscopic methodKinetics of fluorescence decay. In wildtype (curve 1) and mutant strains of Parachlorella kessleri cells (PCMut2- curve 2) and (PCMut4 -curve 3). The measurements were performed with a Fluorolog-3 spectrofluorometer at 685 nm, using TCSPC method with sample activation with light at 1 Mhz frequency with a LED 390 nm by pulses with half-widths of 0.9 ns.Back to article page
