F1v-NixA
Contents
Introduction
This part combined BBa_K5115085(F1v)with BBa_K5115071(NixA). In this way, the NixA is dimerized on the cell membrane.

| Figure 2. Comparison of Ni²⁺ Uptake Efficiency by Different ‘’E. coli’’ in 20 mg/L Ni²⁺.
The graph shows the percentage of Ni²⁺ absorbed by ‘’E. coli’’ expressing different constructs after 5 hours of growth in a medium containing 20 mg/L Ni²⁺ (‘’E. coli’’ strain: BL21 DE3, induced with 1 mM IPTG). Ni²⁺ uptake was calculated based on the difference between initial and final concentrations in the supernatant, divided by 20 mg/L.

The graph shows the percentage of Ni²⁺ absorbed by ‘’E. coli’’ expressing different constructs after 5 hours of growth in a medium containing 30 mg/L Ni²⁺ (‘’E. coli’’ strain: BL21 DE3, induced with 1 mM IPTG). Ni²⁺ uptake was calculated based on the difference between initial and final concentrations in the supernatant, divided by 30 mg/L. The optical density (OD₆₀₀) of the initial bacterial suspension was adjusted to 0.5. Culture for 5 hours, at 37°C with a rotating speed at 220 rpm.
