ClearThe Structural and Functional Responses of Rhizosphere Bacteria to Biodegradable Microplastics in the Presence of Biofertilizers
Researchers studied how biodegradable microplastics interact with biofertilizers in crop soils and found that even though biodegradable plastics are designed as greener alternatives, they still significantly altered soil bacterial communities and disrupted carbon metabolism pathways. The findings suggest that biodegradable microplastics may affect soil health differently than conventional plastics, but are not necessarily harmless.
Distinct influence of conventional and biodegradable microplastics on microbe-driving nitrogen cycling processes in soils and plastispheres as evaluated by metagenomic analysis
Researchers compared how conventional polyethylene and biodegradable microplastics affect nitrogen cycling by soil microbes. They found that biodegradable microplastics caused stronger changes to microbial communities and nitrogen processing pathways than conventional plastics, particularly by enriching certain bacteria on their surfaces. The study suggests that even biodegradable plastic mulch alternatives may significantly alter soil nutrient cycling in agricultural settings.
Nonlinear microbial nutrient limitation responses to biodegradable vs. conventional microplastics under long-term agricultural management
Researchers sampled long-term agricultural plots to compare how biodegradable and conventional microplastics affect microbial nutrient limitation in soil. Both types of MPs altered microbial metabolism, with biodegradable MPs in some cases causing greater disruption to nutrient cycling than conventional plastics.
Deciphering the effects of long-term exposure to conventional and biodegradable microplastics on the soil microbiome
This study compared how conventional and biodegradable microplastics affect soil microbes over long time periods and found that both types significantly changed soil microbial communities and disrupted carbon and nitrogen cycling after extended exposure. Biodegradable plastics, often marketed as eco-friendly, actually released more chemical byproducts than conventional plastics, which matters because these soil changes can affect the food we grow.
The plastisphere of biodegradable and conventional microplastics from residues exhibit distinct microbial structure, network and function in plastic-mulching farmland
Researchers compared the bacterial communities that colonize biodegradable and conventional plastic microplastics in farmland soil. They found that biodegradable plastics (PBAT/PLA) and conventional polyethylene each attracted distinct microbial communities with different functions, including bacteria that could degrade plastics or cycle nutrients. The results suggest that even biodegradable plastics create unique microbial environments in soil that may affect soil health and function in unexpected ways.
Biodegradable and conventional microplastics exhibit distinct microbiome, functionality, and metabolome changes in soil
Researchers compared the effects of conventional plastics (polyethylene and polystyrene) and biodegradable plastics (polylactide and polybutylene succinate) on soil microbial communities. They found that both types of microplastics significantly altered soil microbial composition, but biodegradable microplastics had a more pronounced impact on soil metabolic function and microbial activity than conventional ones.
Discrepant soil microbial community and C cycling function responses to conventional and biodegradable microplastics
Scientists compared how conventional polyethylene and biodegradable polylactic acid microplastics affect soil microbial communities and carbon cycling. Researchers found that the two types of microplastics had markedly different effects, with biodegradable plastics causing more changes to microbial community structure and carbon-related gene activity. The study suggests that biodegradable plastics, while designed to be more environmentally friendly, may still significantly alter soil biology.
Differential responses of soil microbial community structure and function to conventional and biodegradable microplastics
Scientists compared how tiny pieces of regular plastics and "biodegradable" plastics affect helpful bacteria in soil after 6 months. They found that biodegradable plastics actually disrupted soil bacteria more than regular plastics, changing the microbes that help plants grow and cycle nutrients. This matters because these soil bacteria are crucial for growing healthy food, so switching to biodegradable plastics might not be the simple environmental solution we hoped for.
Integrated microbiota and multi-omics analysis reveal the differential responses of earthworm to conventional and biodegradable microplastics in soil under biogas slurry irrigation
Researchers compared how conventional and biodegradable microplastics from agricultural mulch films affect earthworms in soil treated with biogas slurry fertilizer. Using multi-omics analysis, they found that both types of microplastics disrupted earthworm gut bacteria and metabolic pathways, though through different molecular mechanisms. The study suggests that biodegradable plastic alternatives may still pose risks to soil organisms that warrant further investigation.
Microbial resistance in rhizosphere hotspots under biodegradable and non-degradable microplastic amendment: Community and functional sensitivity
Researchers examined microbial community and functional sensitivity in rhizosphere hotspots amended with biodegradable and non-degradable microplastics, assessing how different polymer types affect microbial resistance and functional diversity in agricultural soils.
Succession of soil bacterial communities and network patterns in response to conventional and biodegradable microplastics: A microcosmic study in Mollisol
Using a soil microcosm experiment, researchers compared how conventional polyethylene and biodegradable microplastics affected soil bacterial communities over 90 days across four dosages. Biodegradable microplastics induced greater community dissimilarity from controls and tended to enrich environmentally beneficial taxa, while conventional polyethylene promoted potentially hazardous bacteria.
Effect of conventional and biodegradable microplastics on the soil-soybean system: A perspective on rhizosphere microbial community and soil element cycling
This study compared how conventional polyethylene microplastics and biodegradable alternatives (PBAT and PLA) affect soil bacteria and nutrient cycling in soybean fields. The biodegradable microplastics actually caused more harm to soybean growth than conventional ones, reducing shoot biomass by up to 34% and disrupting nitrogen availability in soil. This challenges the assumption that biodegradable plastics are always better for the environment and raises questions about their impact on agricultural productivity and food security.
Effects of microplastics on common bean rhizosphere bacterial communities
Researchers studied how polyethylene and biodegradable microplastics affect bacterial communities in the root zone of common beans. Both types of microplastics significantly altered the diversity and composition of rhizosphere bacteria, with biodegradable microplastics inducing more distinctive changes than conventional polyethylene at higher concentrations.
Insights into soil microbial assemblages and nitrogen cycling function responses to conventional and biodegradable microplastics
Researchers compared how biodegradable polylactic acid and conventional PVC microplastics affect soil bacteria and nitrogen cycling processes. They found that both types of microplastics altered microbial communities, but biodegradable plastics had distinct effects on nitrogen-processing bacteria and did not simply behave as a harmless alternative. The study suggests that switching to biodegradable plastics may change rather than eliminate the impact of microplastic contamination on soil health.
Soil biota modulate the effects of microplastics on biomass and diversity of plant communities
Researchers used mesocosm experiments with natural soil biota to compare the effects of biodegradable and non-biodegradable microplastics on plant community biomass and diversity. Soil biota modulated the impact of microplastics, with biodegradable plastics showing similar effects to conventional plastics on plant community structure, challenging the assumption that biodegradable alternatives are environmentally benign.
Biodegradable PBAT microplastics adversely affect pakchoi (Brassica chinensis L.) growth and the rhizosphere ecology: Focusing on rhizosphere microbial community composition, element metabolic potential, and root exudates
Researchers compared biodegradable PBAT plastic microplastics with conventional polyethylene microplastics in soil and found that the biodegradable version actually caused more harm to plant growth and soil health. PBAT microplastics reduced nutrient availability, disrupted the soil microbial community, and altered root chemistry more than conventional plastic. This finding challenges the assumption that biodegradable plastics are always safer for the environment.
Effects of different microplastics on the physicochemical properties and microbial diversity of rice rhizosphere soil
Researchers compared how conventional polyethylene and biodegradable polylactic acid microplastics, both fresh and aged, affect rice paddy soil properties and microbial communities. They found that aged microplastics had stronger effects than fresh ones, altering soil pH, nutrient availability, and the composition of root-associated bacteria. The study warns that biodegradable plastics are not necessarily safer for soil health than conventional plastics, especially as they break down over time.
Microbes drive metabolism, community diversity, and interactions in response to microplastic-induced nutrient imbalance
Researchers investigated how conventional and biodegradable microplastics alter soil nutrient balances and the resulting effects on microbial metabolism, community diversity, and species interactions. The study found that microplastic-induced nutrient imbalances significantly influenced soil microbial processes, with different types of microplastics producing distinct effects on carbon and nitrogen cycling.
Biodegradable Polyesters and Low Molecular Weight Polyethylene in Soil: Interrelations of Material Properties, Soil Organic Matter Substances, and Microbial Community
Researchers examined how biodegradable polyesters and low molecular weight polyethylene behave in soil environments, investigating their interactions with soil organic matter and microbial communities over time.
