WebApr 7, 2024 · Unlike chemical or heat-based treatments, enzymatic approaches to environmental degradation of PET plastics potentially generate degradation products such as bis (2-hydroxyethyl) terephthalate (BHET), mono (2-hydroxyethyl) terephthalate (MHET) and terephthalic acid (TPA), which, theoretically, can be reclaimed or released … WebIts optimal pH and temperature were pH 8.0 and 40°C, respectively. The analysis of the enzymatic products showed that EstB could hydrolyze one ester bond of BHET to MHET. To the best of authors' knowledge, this is the first report on the biodegradation characteristics of BHET by a member of the Enterobacter genus.
