PET addition delays the composting mature process and promotes microbiota associated with plastic degradation in plastisphere

Xiaoxiao Li et al.

Summary: Microplastics (MPs) enter forest and turf-grass and non-edible crops through sludge land reuse, posing risks to human health and environmental security. PET MPs have effects on sludge-straw composting and microbial communities, delaying composting humification and altering community composition. Plastics degradation microbiota are enriched in the plastisphere, especially during high thermophilic stage, indicating potential for development of future aerobic fermentation technology for MPs degradation.

Polyethylene mulching film degrading bacteria within the plastisphere: Co-culture of plastic degrading strains screened by bacterial community succession

Peiyuan Wang et al.

Summary: This study aims to investigate the succession of bacterial community in the plastisphere and find the most efficient combination of bacteria for degrading plastics through co-culture. The results show that the diversity of bacterial community in the plastisphere is significantly lower and the community structure is regularly altered. Additionally, three PMF-degrading bacterial strains were selected and the best combination for PMF degradation was identified. This study provides a new possibility for mitigating plastic pollution in agricultural land from the perspective of plastisphere-related research.

Lihua Niu et al.

Summary: This study investigated the microbial degradation of PE/PP resin, which is a type of refractory organic material. The results showed that PE/PP resin degrades slowly in natural rivers, and the enriched PE/PP degrading bacteria exhibit higher abundance and diversity. The distribution of these bacteria is significantly correlated with inorganic nitrogen in sediments.

Enhanced degradation of poly(ethylene terephthalate) by the addition of lactic acid/glycolic acid: composting degradation, seawater degradation behavior and comparison of degradation mechanism

Tian-Yuan Liu et al.

Summary: This study introduced easy hydrolysis sites into non-degradable PET using hydroxy acids, which resulted in the synthesis of high molecular weight PETL and PETG copolyesters. The introduction of hydroxy acid significantly improved the composting and seawater degradation performance of PET. The degradation rate of PETG was faster than that of PETL, with PETG80 achieving a mineralization rate of 22.0%.

The dynamics of macro- and microplastic quantity and size changes during the composting process

Christian Zafiu et al.

Summary: The quantity and type of macro-and microplastics during the composting process were investigated in two state-of-the-art composting plants in Austria. Microplastics >0.2 mm were found after the first turning event in both facilities. The plant with shorter turning intervals generated more microplastics, averaging approximately 21 particles per week and kg- 1 DM during the first four weeks.

Sediment-driven plastisphere community assembly on plastic debris in tropical coastal and marine environments

Jonas Koh et al.

Summary: In this study, plastic debris collected from various coastal ecosystems around Singapore were found to be predominantly influenced by sediment rather than the plastic materials. The plastisphere communities on the plastic debris included potential plastic degraders, bacteria involved in biogeochemical cycles, hygienically relevant bacteria, and potential pathogens. This study highlights the urgent need to understand the fate and ecological impacts of plastic debris accumulated in coastal habitats.

Comparing the bacterial composition, succession and assembly patterns in plastisphere and kitchen waste composting with PLA/PBAT blends

Wenjie Chen et al.

Summary: The dynamics of bacterial composition, succession, and assembly process in different ecological niches (compost and plastisphere) were revealed during kitchen waste composting with the addition of poly lactic acid / poly butylene adipate-co-terephthalate (PLA/PBAT) plastics for 120 days. The results showed that the presence of PLA/PBAT plastics did not significantly affect the safety and maturation of composts, but there were notable differences in bacterial compositions between the plastisphere and composts with PLA/PBAT. The PLA/PBAT plastics may enhance the contribution of deterministic processes on composting bacterial community assembly while enriching pathogens.

Composting-based degradation of poly (ethylene terephthalate) microplastics and its enhancement with exogenous PET hydrolase supplementation

Xiaoyan Qi et al.

Summary: This study aimed to investigate the degradation of PET microplastics (MPs) in high-temperature composting and explored the enhanced degradation by adding thermophilic PET hydrolase. The results showed that after 20 days of composting, the weight of PET MPs significantly reduced by 21.1%, and the addition of PET hydrolase resulted in a further reduction of 32.8%. The surface of PET MPs exhibited noticeable corrosion and oxidation after composting. These findings suggest that composting can effectively degrade PET MPs, and enzyme-assisted composting can enhance the degradation, providing a new approach for addressing environmental microplastics pollution.

The structure and assembly mechanisms of plastisphere microbial community in natural marine environment

Sheng-Jie Zhang et al.

Summary: Recent studies have shown that microbial colonization profiles on microplastics in marine environments have higher diversity and evenness compared to seawater, influenced by environmental factors, polymer types, and exposure duration. Exposure to microplastics increases xenobiotic biodegradation potential and reduces microbial network complexity. Stochastic processes play a greater role than deterministic processes in shaping plastisphere microbial community structure.

Summary: The study revealed the effects of microplastics on microbiota and antibiotic resistance genes in the soil plastisphere. Microbial communities in the plastisphere are involved in diverse metabolic pathways, potentially driving ecological processes in the soil ecosystem. Deterministic processes were found to be more important in explaining the variance in ARGs within plastispheres.

Recent advances in impacts of microplastics on nitrogen cycling in the environment: A review

Maocai Shen et al.

Summary: Nitrogen cycling is crucial in biogeochemistry and is largely influenced by microbial-driven nitrogen transformation. The environmental impact of microplastics is increasingly serious, making the analysis and control of microplastic pollution a research hotspot. This review summarizes the research progress on the effects of microplastics on nitrogen transformation and cycling in water, soil, sediment, and sewage sludge. The presence of microplastics can affect the microbial population, abundance, and type, thereby influencing nitrogen transformation. However, the mechanisms of microplastics on environmental nitrogen transformation and cycling are not fully understood due to the lack of relevant research.

Exploring the influence mechanisms of polystyrene-microplastics on sewage sludge composting

Chuang Ma et al.

Summary: This study explored the influence mechanisms of polystyrene-microplastics (PS-MPs) on sewage sludge composting and found that they can reduce compost temperature and microbial biomass carbon, inhibit the activity of key enzymes, but increase urease activity. PS-MPs can also alter the relative abundance of dominant bacteria and change the relevance of main enzymes and bacterial communities. High levels of PS-MPs mainly affect the composting process by reducing microbial biomass carbon in the mesophilic phase and temperature in the thermophilic phase.
