Abstract

Biopolyurethane composites based on poly(ester urethane), and extracellular matrix components (hydrolyzed collagen, elastin, chondroitin sulfate and hyaluronic acid) have been prepared. The biological material used is a very wide spread aggressive fungal species in all media for life and is represented by Aspergillus brasiliensis (Trichocomaceae, Eurotiales, Eurotiomycetidae, Eurotiomycetes, Ascomycota, Fungi) and Penicillium chrysogenum (Trichocomaceae, Eurotiales, Eurotiomycetidae, Eurotiomycetes, Ascomycota, Fungi). Evaluation of the biologically active potential of these biocomposites against these fungi has been done through inoculation onto Sabouraud–agar nutrient medium. Fungal growth was monitored over 60 days. Visual observations of the fungal growth show that these fungi were aggressive and caused rapid grow after 72 h of inoculation onto Sabouraud-agar nutrient medium, but the biopolyurethane composites samples relatively to the fungal attack particularly showed a different behaviour..
