Poly(ethylene terephthalate) hydrolase (PETase) from Ideonella sakaiensis 201-F6 was expressed and purified Escherichia coli to hydrolyze poly(ethylene (PET) fibers waste for its monomers recycling. Hydrolysis carried out at pH 8 30 °C found be the optimal condition based on measured monomer mono(2-hydroxyethyl) terephthalate (MHET) terephthalic acid (TPA) concentrations after 24 h reaction.
