Protein carbonylation along bench-top trials of biomass propagation. Western analysis of oxidatively damaged proteins (top panels) and total protein stain (bottom panels) for T73 (left panels) and TTRX2 (right panels) strains (A). Panel B shows quantification of protein carbonyl content of T73 (black circles) and TTRX2 (open squares) data shown in panel A. Data was normalized to total protein in Coomassie stained gels. In order to avoid technical errors due to different exposure times, comparison between both strains was carried out in the same experiment. The mean of three independent experiments and standard deviations are shown. Protein carbonylation in samples from both strains between 0 and 65 h were significantly different with p < 0.01, and samples at 70 and 80 h were significantly different with p < 0.05.
