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.

E. coli-arsR/zntA with W6 E. coli-arsR/zntA with YJ20
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

500 524.8 ± 39.3 95.3 491.6 ± 18.6 98.3
  1. + Accuracy was calculated by the coverage of Pb quantification over originally spiked concentrations
