ABSTRACT

Licentious and repeatedly deliberate release of plastics (Polyethylene terephthalate) is responsible for growing environmental pollution. In this study, Penicillium sp., has been isolated from PET (Polyethylene terephthalate) waste and its potential to degrade PET under laboratory conditions have been evaluated through electron microscopic studies. The observation of the present investigation reveal that Penicillium sp. were able to successfully colonies PET flakes surface and induce micromorphological changes like formation of multi-layered dense network of hyphae, ducking, surface corrosion and crystals which was evident in the SEM images.
