Ecology of the plastisphere
AI summary Read the abstract
This review explores the plastisphere, the diverse microbial community that colonizes plastic debris in the ocean, which now spans multiple biomes on Earth. Researchers examine how microplastics serve as novel substrates for microbial colonization and may facilitate the dispersal of microorganisms, including potentially harmful species, across aquatic ecosystems. The study highlights key questions about whether plastics harbor a unique core microbial community distinct from natural surfaces.
The plastisphere, which comprises the microbial community on plastic debris, rivals that of the built environment in spanning multiple biomes on Earth. Although human-derived debris has been entering the ocean for thousands of years, microplastics now numerically dominate marine debris and are primarily colonized by microbial and other microscopic life. The realization that this novel substrate in the marine environment can facilitate microbial dispersal and affect all aquatic ecosystems has intensified interest in the microbial ecology and evolution of this biotope. Whether a 'core' plastisphere community exists that is specific to plastic is currently a topic of intense investigation. This Review provides an overview of the microbial ecology of the plastisphere in the context of its diversity and function, as well as suggesting areas for further research.

AI summary Read the abstract
This review explores the plastisphere, the community of microorganisms that colonize plastic debris in the environment. The authors cover methods for studying these microbial communities, the diversity of organisms found living on plastics, and their functional roles including potential plastic degradation and pathogen harboring. Understanding the plastisphere is important because these microbial communities can influence how plastics break down and what health risks plastic pollution may pose.
Surfing and dining on the “plastisphere”: Microbial life on plastic marine debris
AI summary Read the abstract
This review examines the microbial communities — the "plastisphere" — that colonize floating plastic debris in the ocean, discussing how these biofilms form, who lives in them, and what risks they may pose to marine ecosystems and human health. The unique chemistry and buoyancy of plastic creates a novel habitat that can transport potentially harmful microbes across ocean basins.
Microbial colonization and degradation of marine microplastics in the plastisphere: A review
AI summary Read the abstract
This review explores the "plastisphere" — the community of microorganisms that colonize microplastics floating in the ocean. Researchers found that bacteria, fungi, algae, and other microbes form unique biofilm communities on plastic surfaces, some of which can partially degrade the plastic while others include potentially harmful pathogens. Understanding these microbial communities is important for assessing both the ecological risks and possible bioremediation potential of marine microplastic pollution.
Marine Plastic Debris: A New Surface for Microbial Colonization
AI summary Read the abstract
This review examines the "Plastisphere" -- the community of microbes that rapidly colonizes plastic debris in the ocean -- covering biofilm development, potential biodegradation, and the hitchhiking of harmful bacteria. Researchers found that microbial communities on plastics do not dramatically differ from those on other inert surfaces, especially in mature biofilms. The study identifies key knowledge gaps and calls for more environmentally realistic research into how these plastic-associated microbes interact with marine ecosystems.
