Abstract: La presente invención se refiere a nuevas esterasas, más particularmente, a variantes de esterasas que tienen mejor termoestabilidad comparado con la esterasa de la SEQ ID NO: 1 y a los usos de las mismas para degradar materiales que contienen poliéster, tales como productos de plástico. Las esterasas de la invención son particularmente adecuadas para degradar poli(tereftalato de etileno) y materiales que contienen poli(tereftalato de etileno).

Abstract: The present invention relates to the use of specific enzymes, more particularly of specific esterases having a polyester degrading activity, for the degradation of polyester or polyester containing material in acidic conditions at a pH between 3 and 6. The present invention also relates to a process for degrading polyester or polyester containing material, such as plastic products, comprises a step of enzymatic depolymerization implemented in acidic conditions at a pH between 3 and 6. The process of the invention is particularly suited to degrade polyethylene terephthalate, and polyethylene terephthalate containing material.
