Abstract
Washed Escherichia coli ATCC11775 cells were killed by (-)-epigallocatechin (EGC) in the presence of a non-lethal concentration of Cu2+ (1 mu mol 1(-1 )) without additional H2O2, but not by (-)-epicatechin (EC). EGC alone (<0. 1 mmol 1(-1)) did not reduce the viability of the cells. The survival curve obtained in the presence of EGC and Cu2+ was similar to that obtained in t he presence of (-)-adrenaline (EN) and Cu2+.
