Ecosystem-specific composition and drivers of plastisphere resistome in freshwater and marine environments

Key Points

• The resistome associated with the plastisphere shows significant variation between freshwater and marine environments, indicating ecosystem influence.
• Analysis of microbial communities reveals unique resistome characteristics for both ecosystems, including diverse antimicrobial resistance genes.
• This study utilized metagenomic techniques to assess resistomes across various plastics in differing aquatic settings.
• Understanding these differences may inform strategies for managing pollution and mitigating antimicrobial resistance in diverse ecosystems.
