Figure 2From: Characterization of mercury bioremediation by transgenic bacteria expressing metallothionein and polyphosphate kinaseMercury resistance bioassay. Bacterial clones pBSK-g10-mt1-rpsT (A), pBSK-P16S-g10-mt1-rpsT (B), pBSK-g10-ppk-rpsT (C), pBSK-P16S-g10-ppk-rpsT (D), and untransformed E. coli (E) were grown in LB media with 0, 5, 10, 20, 40, 80, 100, 120, 140, and 160 μM of HgCl2. Bacterial growth was established by measuring the absorbance at 600 nm after 16 and 120 hours. (n ≥3).Back to article page
