The paper presents the research results for enzymatic degradation of biodegradable materials in proteinase K. Polylactide and its composites containing a biostatic substance in the form of sulphanilic acid salt PHMG were tested as part of the research project. Three different concentrations of the biostatic substance were used: 0.2%, 0.6% and 1.0 % of the mass. The research results of differential scanning calorimetry (DSC) for the tested materials were compared both before and after the enzymatic degradation. Photographs obtained from a scanning electron microscope (SEM) and the analysis of the foil physical mass loss confirmed that these materials were susceptible to enzymes.

This study presents the data summary on growth speed of selected species of fungi on some of biodegradable polymer materials. Growth speed was assessed on films composed of poly(lactide), poly(ε-caprolactone) and poly(hydroxybutyrate) after a month of incubation in 24oC. To assess growth of fungi optical microscopy on densitometric measurements were used. Through these analyses the best growth was confirmed for fungus: Chaetomium globosum (ATTC 6205) on a film made of poly(ε -caprolactone).
