Biodegradability of Oxidized Poly(vinyl alcohol) [PDF]
Bioscience, Biotechnology, and Biochemistry, 1996 Poly(vinyl alcohol) dehydrogenase (PVADH) purified from Pseudomonas sp. 113P3 catalyzed an oxidation of poly(vinyl alcohol) (PVA) in the presence of pyrroloquinoline quinone (PQQ) to give a beta-diketone structure on PVA. Although PVADH oxidized not only enzymatically oxidized PVA but also chemically oxidized PVA, PVA-degrading microorganisms ...
