Figure 2From: Analysis and in situ characterization of activated sludge communities capable of benzotriazole biodegradationAerobic biodegradation during a 4-week batch experiment without sampling. Benzotriazole concentrations were determined at the start and the end of the experiment. Shown are mean values of benzotriazole concentrations of duplicate experiments with error bars indicating standard deviations (n = 2).Back to article page
