Short-term physiological and biometrical responses of Lepidium sativum seedlings exposed to PET-made microplastics and acid rain

Ecotoxicology and Environmental Safety, 2021
Plastics enter in terrestrial natural system primarily by agricultural purposes, while acid rain is the result of anthropogenic activities. The synergistic effects of microplastics and acid rain on plant growth are not known.

Efficient catalytic conversion of polyethylene terephthalate to dimethyl terephthalate over mesoporous Beta zeolite supported zinc oxide

Carbon Future
Methanolysis of polyethylene terephthalate to dimethyl terephthalate is a sustainable route for recycling of polyethylene terephthalate (PET) plastic. Herein, we demonstrate that mesoporous Beta zeolite supported zinc oxide (Zn-Beta-meso) is efficient ...

Molecular oxygen-assisted in defect-rich ZnO for catalytic depolymerization of polyethylene terephthalate

iScience, 2023
Summary: Polyethylene terephthalate (PET) is the most produced polyester plastic; its waste has a disruptive impact on the environment and ecosystem. Here, we report a catalytic depolymerization of PET into bis(2-hydroxyethyl) terephthalate (BHET) using ...

In silico Characterization of Poly (ethylene) Terephthalate (PET): Degrading Enzymes from Rhizobacter sp. for Enzymatic Degradation Mechanisms

Journal of Tropical Life Science
Dienelactone hydrolase (DHL) from Rhizobacter sp. is an enzyme from the β‐ketoadipate pathway that belongs to the α/β hydrolase family. It involves the conversion of chloroaromatics, such as nitrophenols and hydrocarbons, into harmless metabolites.
