Fluorescence of recombinant C. reinhardtii—GFP (strain expressing green fluorescent protein) cultivations supplemented with selenocystamine. This oxidative molecule was supplemented to obtain the following final concentrations: 0.0, 0.1, 1.0, 2.0, 5.0, 10.0, 25.0 and 100.0 µM, and these were compared to control w1.1. a 0 h of cultivation; b 8 h; c 24 h; d 48 h; e 72 h; f 96 h. RFU relative fluorescence unit. All error bars were calculated by using the triplicate average values, which were also equalized to cell concentration measurements.
