Abstract
Research on the manufacturing of experimental biodegradable films (EBF) was carried out in the laboratory. Recipes containing 8, 10, and 15% of corn and potato starch were analyzed. It was found that the EBF based on potato starch with a 10% concentration is more plastic and retains its shape well compared to other samples. Microbiological, mechanical, physicochemical, and infrared spectroscopic studies of the EBF and the biodegradable plastics (BP) available on the market in the form of packaging bags that are positioned as biodegradable (BP from ATB, BP from Silpo, BP from Roshen) were performed. The isolation of enrichment soil microbial cultures and their identification by microscopy of permanent mounts were studied. The ability of the isolated microbial cultures to biodegrade starch-based EBFs was experimentally investigated and determined, as well as the peculiarities of biodegradation of starch-based EBFs and BPs, as a result of the activity of microorganisms of different taxonomic groups, were studied.
