Metagenomic of plastisphere from Mediterranean Sea

Plastic debris are accumulating in the marine environment and aggregate microorganisms that form a new ecosystem called the plastisphere. Better understanding the plastisphere is crucial as they have self-sufficient organization, carrying pathogens or organisms that may be involved in the pollutant adsorption and/or plastic degradation. To date, the plastisphere is mainly described at the taxonomic level and the functioning its microbial communities still remains poorly documented. In this work, metagenomic and metaproteomic analyzes were performed on the plastisphere of polypropylene and polyethylene plastic debris sampled along the Mediterranean Sea coast. This work brings a new insight in the functioning of microbial plastisphere developed on plastic marine debris.
