-

Sphingopyxis sp.

-

degradation of polyvinyl alcohol must be performed by periplasmic polyvinyl alcohol dehydrogenase after uptake into the periplasm. A specific ultrastructural change on the cell surface is induced by polyvinyl alcohol and enhances the uptake of polyvinyl alcohol in the Sphingopyxis sp. strain 113P3
