Dynamics and functions of microbial communities in the plastisphere in temperate coastal environments
Researchers explored microbial communities colonizing microplastics in coastal environments of Japan, comparing bacterial and fungal communities across different plastic types, water, sediment, and sand. The study found that while microbial communities varied by sample type and location rather than plastic shape, microplastics harbored hydrocarbon-degrading organisms as well as potential pathogens, highlighting the ecological significance of plastic-associated biofilms.
Can Microplastic Pollution Change Important Aquatic Bacterial Communities?
Microplastics in coastal sediments can change the composition of important bacterial communities that cycle nutrients and maintain ecosystem health. Microplastic-associated bacteria differ significantly from natural sediment bacteria, with potential consequences for the chemical processes these communities perform.
Microplastic pollution and its relationship with the bacterial community in coastal sediments near Guangdong Province, South China
This study systematically characterized microplastic pollution in coastal sediments near Guangdong Province, China, and found that microplastic abundance was linked to changes in the local bacterial community.

Gut microbiota composition of the isopod Ligia in South Korea exposed to expanded polystyrene pollution
Coastal isopods (Ligia) collected from a plastic-polluted site in South Korea showed measurably different gut microbiome compositions compared to those from a clean site, with lower species richness in polluted areas. This suggests that microplastic contamination can reshape the internal microbial communities of small invertebrates, potentially affecting their health and their role in coastal food webs.
Unveiling the impact of microplastics with distinct polymer types and concentrations on tidal sediment microbiome and nitrogen cycling
Researchers tested how five different types of microplastics at varying concentrations affect microbial communities and nitrogen cycling in tidal sediments over 30 days. They found that microplastics generally reduced microbial diversity and enhanced nitrogen fixation, with biodegradable PLA plastic showing concentration-dependent effects. The study suggests that microplastic contamination in coastal sediments can disrupt important nutrient cycling processes driven by microorganisms.

Bacterial community structure of water, sediment and microplastics in Poyang Lake wetland.
This study compared the bacterial communities living on four types of microplastics (film, foam, fiber, and fragment) in Poyang Lake wetland in China against the bacterial communities in the surrounding water and sediment. The microplastic surfaces hosted distinct microbial communities that differed from both the water and sediment, with foam microplastics supporting the least diverse communities. This "plastisphere" research is important because the unique bacteria colonizing plastic surfaces could spread pathogens or alter nutrient cycles in freshwater wetland ecosystems.
