Homogenization of bacterial plastisphere community in soil: a continental-scale microcosm study
Researchers conducted a large-scale study across 99 sites in China to examine how bacteria colonize microplastics in soil compared to surrounding soil communities. The study found that bacterial communities on polyethylene microplastics were much more uniform than those in the soil itself, suggesting that the consistent properties of plastic surfaces drive a standardized microbial community. Evidence indicates that soil pH, carbon content, and temperature all influence how different the plastic-associated bacteria are from nearby soil microbes.
The microplastics distribution characteristics and their impact on soil physicochemical properties and bacterial communities in food legumes farmland in northern China
Researchers surveyed farmland soil across five provinces in northern China and found microplastic contamination ranging from 1,600 to over 36,000 particles per kilogram of soil. Most of the microplastics were small fibers and fragments, primarily from agricultural plastic film and organic fertilizer use. The study found that microplastic presence altered soil properties and shifted bacterial community composition, suggesting these particles may affect soil health in food-growing regions.
