Part:BBa_K2360012
pChrB-ChrB+SRRz+rrnB terminater
It is a high-efficiency chromium detecting device. This device consist two parts, the lysis module (BBa_K2360000) and chromium detecting module(BBa_K2360007).The lysis gene will be expressed when the detecting module makes a response to the metal ions, which will make bacterial cleavage, resulting in the decrease of OD600, we measured the growth curve of the engineering bacteria in different concentration of metal ions to prove its function. We can just transform the plasmid to E.coil BL21 to detect the chromium ion.

We measured the growth curve of our engineering bacteria in different concentration of nickel ions. It was a pity that we found the OD600 of E. coli with did not decline after we added Cr6+, which showed this device did not work as we expected.
