Poly (Vinylalcohol-Co-Ethylene) Biodegradation on Semi Solid Fermentation by Phanerochaete chrysosporium

ABSTRACT: The biodegradation of the poly (vinylalcohol-co-ethylene) films (EVOH) was studied in semi-solid fermentation (SsF) with the Phanerochaete chrysosporium fungus, using as substrate a mixture of equal amounts of corncob and cornhusk. The initial humidity of the system was adjusted with basal medium between 70% and 90%. The EVOH films were analyzed by both infrared (IRTF) and differential scanning calorimetry (DSC), after 16 and 19 days of incubation. The results showed that in the system with higher humidity percent, the activity of lignin peroxidase (LiP) enzyme was more stable and the degradation of the chemical structure of the EVOH film was significant.
