Influence of polyphenols on Escherichia coli resistance to oxidative stress.

Free radical biology & medicine - 15 Mar 2009

Abstract excerpt

Among all polyphenols tested (tannic acid and flavonoids belonging to different subclasses) only tannin and quercetin significantly enhanced resistance of Escherichia coli to peroxide stress. Pretreatment of the cells with quercetin and tannin resulted in a decrease in the growth arrest duration under moderate H(2)O(2) concentration (2 mM) and an increase in survival under high (10 mM) doses. The shorter growth...
