Constitutive PETase Coding Device
This is optimized coding sequence of PETase enzyme for E. coli BL21 with the addition of constitutive promoters BBa_J23106.
SEM (Scanning Electron Microscopy) Analysis
In order to observe the ability of our bacteria (transformed with BBa_K2378005) to degrade PET plastic, we ran a qualitative SEM analysis. PET plastic bottles were cut into 1x1 cm fragments with uniform weights. The plastic fragments were then washed with ethanol and water, followed by incubation in LB media contaning the bacterial transformants for 2 days. Following that, the plastic fragments were once again washed, dried, and finally observed under Scanning Electron Microscope (SEM). As the control, the plastic fragments were treated with bacterial cells without plasmid containing PETase. SEM results show significantly rougher surface with more cracks in samples treated with BBa_K2378005 transformants compared to its control. We can thus conclude that BBa_K2378005 works as intended in biodegrading PET plastics.
