Safe Project Design
Even though one of the organisms we chose as our chassis is listed as biosafety level 2, our project does not present any danger to animals, humans or plants. But, one of the problems in module II, which is the bioleaching by C. violaceum, is the production of cyanide, which is required for the recovery of gold. For this, we designed a cyanide degradation system, where another C. violaceum strain will be modified in order to overexpress cyanide hydratase, a cyanide degradation enzyme.
Due to the complications in fully degrading the cyanide, we must determine the concentration of cyanide left at the end of the process in order to be able to do a proper disposal. This is done according to the NMX-AA-058-SCFI-2001 federal regulation, which establishes the guidelines for the determination of total cyanide in natural, drinking, wastewaters and wastewaters treated. Once this is done, the proper disposal of it must be done, according to the NOM-157-SEMARNAT-2009 federal norm, which establishes the elements and procedures to implement the disposal of mining residues, including cyanide.
