Abstract
To increase the proportion of tannin-resistant bacteria it is necessary to know the mechanism of tannin-resistance. Wattle condensed tannins were determined to be toxic to Escherichia coli in aerobic medium primarily because they generate hydrogen peroxide. The oxidative stress response helps E. coli strains to overcome this inhibitory effect.
