Fig. 1From: Cupriavidus pinatubonensis AEO106 deals with copper-induced oxidative stress before engaging in biodegradation of the herbicide 4-chloro-2-methylphenoxyacetic acid a Determination of intracellular ROS accumulation of cells exposed to 1Â mM H2O2. The histogram shows ROS accumulation detected as green fluorescence from ROS-dependent oxidation of the ROS-sensitive probe H2DCF-DA following 30Â min of incubation in the presence of H2O2. The experiment was repeated twice in triplicates; the histogram here shows fluorescence values from one representative replica. b Viability of cells following 2 and 8Â h of exposure to 1Â mM H2O2 measured as cells with intact membranes not stained by propidium iodide. Data are mean values from triplicate cultures from one representative experiment (the experiment was repeated twice). Error bars represents standard deviationsBack to article page
