Polyethylene adipate
Polyethylene adipate (or PEA), is a pre-polymer of polyurethane often blended with other polyesters to get soft areas. A strain of Penicillium 14-3 can degrade it. Lipases from R. arrizus, R. delemar, Achromobacter sp. and Candida cylindracea; as well as an esterase from hog liver also degraded PEA.
