Identification of Microorganisms Related to Microplastics
AI summary Read the abstract
Plastic debris in aquatic environments attracts diverse microbial communities that differ from those in surrounding water, with these plastisphere microorganisms influencing both the degradation fate of plastics and the dispersal of potentially pathogenic or plastic-degrading microbes. Identifying which microorganisms colonize microplastics is essential for understanding both environmental risks and potential bioremediation opportunities.
The potential of plastic debris to serve as alternative substrates for various biota have gained interest in recent years. In particular, studies on microbial colonization revealed their impacts and roles on the fate and potential risks of the plastic material,...

Identification of Microorganisms Related to Microplastics
AI summary Read the abstract
Plastic debris in aquatic environments is rapidly colonized by diverse microbial communities, with phototrophic organisms like cyanobacteria and diatoms attaching first before being succeeded by proteobacteria, forming what is known as the plastisphere. These microbial biofilms can alter plastic degradation rates and potentially harbor and transport pathogenic organisms, adding a biological dimension to microplastic pollution risks.
Microbial Relationship of Marine Microplastics
AI summary Read the abstract
Researchers examined how microplastics in the ocean interact with microbial communities, finding that plastic surfaces attract and harbor unique assemblages of bacteria — a concern because these 'plastisphere' microbes can spread pathogens and antibiotic-resistant genes through marine food chains.
Microbial Colonization and Degradation of Microplastics
AI summary Read the abstract
This review examined microbial colonization of plastic surfaces—the plastisphere—and assessed the potential of specialized microorganisms to biodegrade plastic polymers as a remediation strategy. Understanding the plastisphere is also critical because biofilm-forming microbes can alter microplastic surface chemistry and influence how particles interact with living organisms that ingest them.
Role of Microorganisms in Biodegradation of Microplastics
AI summary Read the abstract
Researchers examine how microorganisms degrade common microplastic polymers including polyethylene, polypropylene, PVC, and PET, reviewing the enzymatic and metabolic pathways bacteria and fungi use to break down these persistent materials and the potential for harnessing microbial activity as a biodegradation strategy.
Microplastic: A New Habitat for Biofilm Communities
AI summary Read the abstract
Microplastics entering aquatic environments are rapidly colonized by microorganisms that form biofilms, creating a unique ecological niche known as the 'plastisphere' that differs markedly from surrounding water communities. These biofilms can harbor pathogens and antibiotic-resistant bacteria, raising concerns about microplastics serving as vectors for harmful microorganisms throughout aquatic food chains.
