Figure 4From: Characterization of mercury bioremediation by transgenic bacteria expressing metallothionein and polyphosphate kinaseVisual changes in transgenic bacteria under mercury conditions. Black arrows indicate areas of aggregation, precipitation, and color change. A, pBSK-P16S-g10-ppk-rpsT bacteria at 80 μM of HgCl2. B, pBSK-P16S-g10-mt1-rpsT bacteria at 120 μM of HgCl2. Pictures were taken after 72 hours of growth.Back to article page
