Abstract

  Polyurethanes are a group of heteropolymers, they are widely used in many areas of modern life due to their versatility and durability and they have a wide application area of plastic. The accumulation of plastic waste in the environment causes large-scale pollution with long-term effects, making plastic waste management expensive and problematic. However, the disposal of polyester polyurethane wastes makes biodegradation studies important because of their slow recycling processes and their destruction can create toxic compounds. Studies conducted to date have focused on bacteria and many reports on bacterial biodegradation have been published, but it has been discovered that the main microorganisms responsible for biodegradation are fungi. Therefore, the need for the investigation of fungal communities in PU biodegradation continues. Recently published reports draw attention to the new niger group Aspergillus with biodegradation capacity such as Aspergillus tubingensis. In this study, 10 Aspergillus section nigri members were isolated from soil contaminated with plastic waste, were determined by phenotypic and molecular methods and biodegradation was carried out in 3 stages. The results were confirmed by SEM micrograph and ATR-FTIR spectroscopy and visible physical changes. Thanks to our study, it is aimed to study the details of biodegradation of polyester polyurethanes, which constitute a significant part of the plastic waste amount, thanks to Aspergillus section nigri group molds in nature and to be a data for future research.
