A Study of the Effects of Microplastics on Microbial Communities in Marine Sediments
Summary
This study investigated how the presence of microplastics in marine sediments affects microbial communities and, specifically, the methane cycle, finding that microplastics significantly altered microbial community structure and function. Since marine sediment microbes play a critical role in regulating greenhouse gas emissions, microplastic contamination could have broader climate-relevant effects beyond direct toxicity.
With the growing problem of plastic pollution, the impact of microplastics on marine ecosystems and their potential role in microbial communities and methane cycling in marine sediments has become an important topic in environmental science research. This paper aims to investigate the effects of microplastics on microbial communities, in particular the methane cycle, in marine sediments. By analysing the physical and chemical properties of microplastics and their distribution in sediments, the study found that microplastics significantly altered the structure and function of microbial communities. The results suggest that microplastics provide new attachment substrates for microorganisms and influence methane cycling processes. These findings are crucial for understanding the deep-seated effects of microplastic contributions to the global greenhouse effect and for developing effective management strategies for the marine environment. The results of this study highlight the urgency of strengthening the monitoring and management of marine microplastic pollution and provide other scientists and researchers with insights into the interactions between microplastics and marine ecosystems, laying the groundwork for the development of effective strategies to reduce microplastic pollution.

Microplastics Affect Anaerobic Oxidation of Methane and Sedimentary Prokaryotic Communities in Cold Seep Areas
Laboratory experiments exposing cold seep seafloor sediments to microplastics for 120 days showed that polyamide and PET microplastics reduced methane oxidation rates to roughly a third of normal and altered the bacterial communities responsible for this process. Cold seep sediments are major global sinks for methane, so microplastic disruption of this microbial activity could have implications for greenhouse gas cycling in deep ocean environments.
Revealing the response of microbial communities to polyethylene micro(nano)plastics exposure in cold seep sediment
Researchers explored how polyethylene micro- and nanoplastics affect microbial communities in cold seep ocean sediments over a 120-day experiment. While the plastics did not significantly change overall microbial diversity, they did alter the community structure and affected methane-related metabolic processes. The study suggests that plastic pollution could interfere with important deep-sea biogeochemical cycles, including those involved in methane regulation.
Microplastics and their mechanisms in influencing methane oxidation: A physiological and ecological perspective
This review examines the physiological and ecological mechanisms by which microplastics influence methane oxidation processes in the environment, synthesising current understanding of how ubiquitous plastic contamination may disrupt microbial communities responsible for mitigating methane — a greenhouse gas 20-30 times more potent than CO2.
Effects of microplastics on greenhouse gas emissions and microbial communities in sediment of freshwater systems
Researchers found that PET microplastics of different sizes significantly affected greenhouse gas emissions and microbial communities in freshwater sediments, with smaller particles (5 micrometers) notably increasing methane emissions and altering nutrient cycling over 90 days.
Effects of Different Types of Microplastics on Cold Seep Microbial Diversity and Function
Researchers simulated deep-sea cold seep conditions to study how different microplastics affect microbial communities. They found that microplastics made the plastisphere microbial networks more fragile than surrounding environments and disrupted nitrogen cycling and methane metabolism, while potentially concentrating pathogenic species.
