This strain of Alternaria was isolated as a contaminant growing on the lid of a polystyrene petri plate at the National Renewable Energy Laboratory. Alternaria (phylum Ascomycota) is commonly known for its saprophytic, necrotrophic and allergenic qualities (Dang et al. 2015). They are well-known producers of secondary metabolites (Montemurro N et al. 1992). There have been a few reports on the ability of Alternaria to breakdown polyurethane (Magnin 2019, Matsumiya, et al. 2010), which has raised interest in using this fungi towards polyurethane recycling and upcycling. This isolate has been tested for growth on soluble polyurethane as a substrate. With the current interest in circular economy, this fungus could play an important role in gaining fundamental understanding of polyurethane metabolism in fungal systems.
