Figure 4From: Reduction of oxidative cellular damage by overexpression of the thioredoxin TRX2 gene improves yield and quality of wine yeast dry active biomassCatalase activity along bench-top trials of biomass propagation for T73 ( black bars ), T GSH1 (grey bars) and T TRX2 ( white bars ) strains. Average of three independent experiments and standard deviations are shown. Catalase activity was significantly different (p < 0.05) at time points marked by asterisks.Back to article page
