FIG 3.
Bioavailability of Ag+ following reduction by pyocyanin. A solution of Ag+ (100 μM) was reduced in the presence of pyocyanin (5 μM) and NADPH (100 μM) in water (pH 7.0; 32°C), and the concentration of Ag+ was determined at the commencement (0 min) and conclusion (12 min) of the reaction (values are means plus standard deviations [error bars] from three independent experiments).
