Hydrolysis of amorphous PET films by PHL7: (A) Initial reaction velocity expressed as TPAeq (sum of TPA and MHET) released from G‐PET films within 1 h of reaction as a function of enzyme concentration. A curve fit of the initial velocity was performed with a Langmuir type heterogeneous kinetic model.[ 14 , 39 ] (B) Specific G‐PET film hydrolysis activity of PHL7 and LCC at different reaction times with 0.6 mgenzyme gPET −1. (C) TPA and MHET released from G‐PET films by PHL7 and LCC within 16 h of reaction time with 0.6 mgenzyme gPET −1. (D) Comparison of the weight loss of G‐PET films after reaction times of 4, 8, and 16 h with 0.6 mgenzyme gPET −1 of PHL7 and LCC.
