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 novel esterases, more particularly to esterase variants having improved activity and/or improved thermostability compared to the parent esterase of SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3 in acidic conditions and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate in acidic conditions.
