塑料在环境中积累，地中海是世界上污染最严重的海洋之一。塑料表面迅速被微生物定殖，形成塑料球。我们独特的采样提供了来自法国南部四个水生生态系统（河流，河口，港口和近海）的22个地理位置的107个塑料件，以更好地了解影响生物膜组成的参数。同时，进行48个富集培养以研究塑料球中塑料降解细菌的存在。在这种情况下，我们表明，微生物群落结构的最重要的驱动因素是采样地点其次是聚合物的化学组成。致病菌属分布的研究强调，与自然环境相比，我们的塑料样品中只有11%含有较高比例的弧菌。最后，富集培养的结果显示了一系列碳氢化合物降解微生物，表明它们在塑料降解中的潜在作用。
Plastics accumulate in the environment and the Mediterranean Sea is one of the most polluted sea in the world. The plastic surface is rapidly colonized by microorganisms, forming the plastisphere. Our unique sampling supplied 107 plastic pieces from 22 geographical sites from four aquatic ecosystems (river, estuary, harbor and inshore) in the south of France in order to better understand the parameters which influence biofilm composition. In parallel, 48 enrichment cultures were performed to investigate the presence of plastic degrading-bacteria in the plastisphere. In this context, we showed that the most important drivers of microbial community structure were the sampling site followed by the polymer chemical composition. The study of pathogenic genus distribution highlighted that only 11% of our plastic samples contained higher proportions of Vibrio compared to the natural environment. Finally, results of the enrichment cultures showed a selection of hydrocarbon-degrading microorganisms suggesting their potential role in the plastic degradation.
