The first trials to produce ECOL were produced in shaking flask with various designs (from 100&nbsp;mL<sup>-1</sup> to 1&nbsp;L flasks, with and without baffles) and under different conditions. The  parameters tested during our screening experiments were temperature (27&nbsp;°C,30&nbsp;°C and 37&nbsp;°C), concentrations of chloramphenicol (20-170&nbsp;µg&nbsp;mL<sup>-1</sup>), various induction strategies ([http://2012.igem.org/Team:Bielefeld-Germany/Protocols/Materials#Autoinduction_medium autoinduction] and manual induction) and cultivation time (6 - 24&nbsp;h). Furthermore it was cultivated with and without 0.25&nbsp;mM CuCl<sub>2</sub> to provide a sufficient amount of copper, which is needed for the active center of the laccase. Based on the screening experiments we identified the best conditions under which ECOL was expressed. The addition of CuCl<sub>2</sub> did not increase the activity, so it was omitted.

subclass B1 metallo-beta-lactamase NDM-23, codon optimized in E. coli

NDM-23 is a type of subclass B metal beta-lactamases, which is derived from NDM-1 mutation. The beta lactamases of the NDM family can hydrolyze almost all available beta lactam antibiotics (except aztreonam) clinically, including the broad-spectrum antibiotic carbapenems. Because of the extensive substrate profile of this enzyme, the clinical strains carrying it become a great threat to human life and health.
