Evolution means the adaptation of an organism to environmental conditions. So did a variety of microorganisms, who have learned to use plastic components as an energy source.

Kristie Tanner from Darwin Bioprospecting Excellence in Valencia knows some of them very well, and she gives us some insights into her work, especially, within the BBI project ENZYCLE (www.enzycle.eu), where also acib is a partner.
