Abstract

A laboratory study for biodegradation of polymer film materials (high-density and low-density polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride) under the action of mircomycete strains isolated under conditions of the island of Cuba was carried out. The maximum growth of micromycetes was observed in case of PVC samples. The minimum level of biodegradation for PVC films revealed at the mould resistance test (28 days) was confirmed by the results of tensile testing.
