The iGEM Team successfully produced four active bacterial laccases and an eukaryotic laccase (click for the results):

All four laccases (ECOL, BPUL, BHAL and TTHL) we accomplished to purify. Besides the successfully scale-up fermentation, those laccases could be purified in a high amount to characterize the optimal activity conditions regarding pH, temperature, buffer solutions and organic solvent resistance. Furthermore the iGEM Team Bielefeld demonstrated that the produced laccases can be immobilized maintaining their activity and the degradation capacity was screened for several micro-contaminants. These tests indicate that the ECOL and BPUL are able to degrade ethinyl estradiol and estradiol.
