Fig. 2From: Understanding gold toxicity in aerobically-grown Escherichia coliEffects of ROS scavengers on the viability of gold-exposed E. coli. Viability of cells treated with 200 µM HAuCl4 was assessed in the absence (control) and presence of the toxicant and the scavengers 2,2 bipyridil (1 mM) and ascorbic acid (10 mM). Data represent the average of 3 independent trials ± SDBack to article page
