Table 2 Quantification of Pb in artificially contaminated water samples using genetically engineered E. coli biosensors

From: Derivation of pb(II)-sensing Escherichia coli cell-based biosensors from arsenic responsive genetic systems

Spiked conc. [µM]	E. coli-arsR/zntA with W6		E. coli-arsR/zntA with YJ20
Spiked conc. [µM]	Determined conc. [µM]	Accuracy ⁺ (%)	Determined conc. [µM]	Accuracy (%)
100	101.3 ± 11.1	99.0	96.3 ± 10.1	96.3
250	257.9 ± 14.6	96.9	254.3 ± 31.5	98.3
400	416.5 ± 31.0	96.0	381.4 ± 38.9	95.2
500	524.8 ± 39.3	95.3	491.6 ± 18.6	98.3

⁺ Accuracy was calculated by the coverage of Pb quantification over originally spiked concentrations
