Plastisphere: Marine Microbial Assemblages for Biodegradation of Microplastics
AI summary Read the abstract
Researchers reviewing the plastisphere — microbial communities colonizing marine plastic debris — found that these assemblages harbor plastic-degrading microorganisms and examined their potential role in biodegrading microplastics, while also noting risks of pathogen dispersal on plastic surfaces.
The emergence of plastic waste from industries is a serious ecological concern. In recent years, plastic has been identified in various ecosystems, including human tissues, posing a threat to the biotic components of the Earth and giving rise to potential...

Biodegradation of Microplastics by Microbes
AI summary Read the abstract
Researchers examined how microplastic-degrading bacteria break down polymer structures by secreting hydrolytic extracellular enzymes including lipase, keratinase, and cellulases, providing foundational insight into the enzymatic pathways that underpin microbial biodegradation of plastic particles.
Microbial Degradation of Microplastics
AI summary Read the abstract
Microbial communities capable of colonizing and partially degrading plastic surfaces have been identified across global environments, raising the possibility of harnessing them for bioremediation of the plastic pollution crisis. However, current microbial degradation rates are far too slow to keep pace with plastic production, making engineered enhancement of these pathways a research priority.
Microbial Degradation of Microplastics
AI summary Read the abstract
Researchers reviewed microbial degradation mechanisms for microplastics, identifying bacterial and fungal species capable of colonizing plastic surfaces and breaking down polymer chains through enzymatic activity, though noting that degradation rates under environmental conditions remain too slow to address current pollution levels.
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.
