In this study, the occurrence of the most common types of bacteria and fungi on the surfaces of production lines, raw materials and finished products in plastics processing plants was investigated. In addition, the ability of selected bacterial strains to form biofilms and to degrade PS surfaces was determined. The surfaces examined mainly contained aerobic mesophilic bacteria (42.0% of the samples), followed by moulds (30.0%) and representatives of the genera Bacillus (28.3%) and Staphylococcus (19.9%). Growth on the solid medium with polystyrene was confirmed in 63 (63.4%) of the 96 selected strains, but only 3 (3.0%) of them were able to form a clear zone around the colonies. The highest weight loss of polystyrene was observed in the presence of Bacillus strains. The degree of degradation after 30 and 60 days ranged from 0.12–0.78% and from 0.21–2.15%, respectively. The number of living cells in biofilms on surfaces was lowest for the Gram-negative strains Burkholderia and Moraxella and highest for most Bacillus and some Micrococcus strains. Fourier transform infrared spectroscopy revealed differences in the ratios of vibrational bands after exposure to bacterial strains, although no oxygen-containing functional groups were observed on the surface of polystyrene samples. The average contact angle values of polystyrene surfaces exposed to the tested bacterial strains decreased from 80.55 ± 0.39° to 73.64 ± 0.45° after 60 days of incubation. Some isolated bacterial strains from plastic production plants show the potential for more intensive degradation of such materials, which could have an impact on the quality and shelf life of plastic products.
