Micron/submicron-sized plastic debris in the environment is a global issue of increasing concern and may harm human health. A large number of studies have shown that plastic debris has various toxicological effects on different organisms. Thus, efforts have increased to replace conventional plastics with bioplastics. However, investigations on the relation of submicron-sized bioplastics- and conventional plastics to culture-dependent biofilm formation and their similarities and discrepancies are still very limited. For this purpose, two end products made from bioplastics and their equivalent end products from conventional plastics were used to examine the response of the biofilm formation of selected clinically important bacteria. To evaluate the similarities and differences of submicron-sized bioplastics and conventional plastics on biofilm formation, the physicochemistry (particle size, zeta potential, chemical composition, and surface chemistry) of the tested plastics was examined, as well as the characteristics of the biofilms (categorization, protein/carbohydrate).

临床上重要的细菌在生物基和常规微/亚微米级塑料上的生物膜形成。

环境中的微米/亚微米级塑料碎片是一个日益受到关注的全球性问题，可能会危害人类健康。大量研究表明，塑料碎片对不同生物具有多种毒理作用。因此，加大了用生物塑料代替常规塑料的努力。但是，对亚微米级生物塑料和常规塑料与依赖于培养物的生物膜形成之间的关系及其相似性和差异的研究仍然非常有限。为此，使用了两种由生物塑料制成的最终产品和它们与常规塑料相同的最终产品，以检查所选临床上重要细菌的生物膜形成的响应。
