Antioxidant defenses in biofilms of STEC: (a) SOD activity (%)/BBU and (b) CAT (U)/BBU in TSB; with addition of 0.5% glucose; in thioglycollate medium and in thioglycollate medium with addition of 0.5% glucose. Each column shows the mean ± SEM of three independent experiments. ^∗𝑃<0.01 respect to TSB and ^#𝑃 versus thioglycollate medium<0.01.
