Abstract

Though several alternate strategies have been devised to degrade plastic, usage of microbes to degrade plastics is a challenging one. In this study, fungi  has been isolated from PET (Polyethylene terephthalate) and  PS foam (polystyrene foam) waste and its  potential to degrade PET and PS foam both under laboratory  and field burial (soil,cow dung and sewage) conditions have been evaluated through electron microscopic studies. The observation of the present investigation reveal that fungal species (Aspergillus sp., Penicillium sp. and Fusarium sp.)  were  able to successfully colonise PET and PS foam  flakes surface and induce  micromorphological  changes like formation of holes, duckings, surface corrosion and crystals, which was  evident in the SEM image. Thus fungal species (Aspergillus sp., Penicillium sp. and Fusarium sp.) could be used as biological agents to degrade PET and PS foam.
