Fig. 3From: Non-antibiotic pharmaceuticals promote conjugative plasmid transfer at a community-wide levelEffects of non-antibiotic pharmaceuticals on ROS production in donor and recipient bacteria. a Fold change of ROS production percentage in donor bacteria. b Fold change of ROS production percentage in recipient activated sludge bacteria. Significant differences between non-antibiotic pharmaceutical-dosed samples and the solvent control were analyzed by independent-sample t test with Benjamini–Hochberg multiple comparison testing, *P < 0.05, **P < 0.01, *** P < 0.001Back to article page
