Figure 4From: Sequencing and expression of two arsenic resistance operons with different functions in the highly arsenic-resistant strain Ochrobactrum tritici SCII24TGrowth of E. coli AW3110 containing different constructs in the presence of arsenite (A and B), arsenate (C) and antimonite (D). Arsenite and antimonite resistance assays were performed in LB medium and arsenate growths were performed in low-phosphate medium. Each data point represents the results of three independent assays. The error bars indicate standard deviations. O.D. 600 nm, optical density at 600 nm.Back to article page
