polyethylene terephthalate (PET): thermoplastic polymer resin of the polyester family used in fibers for clothing, containers for liquids and foods. Substrates of enzyme of the following families of enzymes: Tannase; Carbon-carbon_bond_hydrolase; Polyesterase-lipase-cutinase used in palstic degradation. The product of hydrolysis can be found as inhibitor. Degradation of PET using hydrolytic enzymes leads to the release of hydrolysis products such as BHET (bis(2-hydroxyethyl) terephthalate), MHET (mono-(2-hydroxyethyl) terephthalic acid), TPA (terephthalic acid) and EG (ethylene glycol). Phthalate esters are endocrine disruptors.
