This work examines biodegradational changes in two types of polymer – biodegradable (polylactide, PLA) andconventional (polyethylene terephthalate, PET) – which have similar uses in industry. The main objective of thisproject was to select rhizosphere bacteria and fungi that were plant growth promoting microorganisms (PGPM)to accelerate the biodegradation of PLA and PET in soil in which selected plant species were cultivated. A potexperiment was conducted to evaluate polymer biodegradation in compost soil in which three plant species werecultivated: rape (Brassica napus), miscanthus (Miscanthus x giganteus), and willow (Salix viminalis). Plant growthwas additionally stimulated by inoculation with two bacterial (Arthrobacter sulfonivorans, Serratia plymuthica) ortwo fungal strains (Clitocybe sp., Laccaria laccata). The strains used in the experiment were selected for theirhydrolytic activity and their ability to grow in vitro on plastics. In the case of the bacteria, the ability to create abiofilm on both types of studied polymers was identified. Biodegradation changes in the plastics were assessedbased on changes in both their surface structure and physical and chemical properties after a 6-month incubationin the soil. Biodegradation of the analysed sheets was most rapid in the presence of the S. plymuthica and L.laccata strains. The presence of PLA in the inoculated soil lowered the soil pH and increased its redox potential aswell as increased the abundance of fungi and bacteria in the soil. The experiment confirmed the stimulatingeffect of the S. plymuthica and L. laccata strains on plant biomass.
