Abstract:
Disclosed are a recombinant poly(ethylene terephthalate) hydrolase (PETase) expression vector, a recombinant mono(2-hydroxyethyl)terephthalate hydrolase (MHETase) expression vector, a strain for producing each of the recombinant PETase and MHETase containing each of the vectors, and a method for degrading a plastics using each of the recombinant PETase and MHETase expressed therefrom. When the recombinant hydrolases, that is, PETase and MHETase are used together, high enzymatic activity may be sustained for a long time to completely degrade the PET.
