Summary
Growth of Aspergillus niger and Cladosporium herbarum occurred in shake cultures with polyurethane as the sole nutrient source. Simultaneously, the isocyanate almost completely disappeared from the polyurethane as determined with an IR-spectroscope. Otherwise, no structural changes were found in the polyurethane, though both fungi penetrated into the resilient foam tested.
