Unveiling Fragmentation of Plastic Particles during Biodegradation of Polystyrene and Polyethylene Foams in Mealworms: Highly Sensitive Detection and Digestive Modeling Prediction

Environmental Science & Technology, Год журнала: 2023, Номер 57(40), С. 15099 - 15111

It remains unknown whether plastic-biodegrading macroinvertebrates generate microplastics (MPs) and nanoplastics (NPs) during the biodegradation of plastics. In this study, we utilized highly sensitive particle analyzers pyrolyzer-gas chromatography mass spectrometry (Py-GCMS) to investigate possibility generating MPs NPs in frass polystyrene (PS) low-density polyethylene (LDPE) foams by mealworms (Tenebrio molitor larvae). We also developed a digestive biofragmentation model predict unveil fragmentation process ingested The removed 77.3% PS 71.1% PE over 6-week test period. Biodegradation both polymers was verified increase δ13C signature residual plastics, changes molecular weights, formation new oxidative functional groups. accumulated due biofragmentation, with exhibiting maximum percentage number at 2.75 7.27 μm, respectively. Nevertheless, were not detected using laser light scattering sizer detection limit 10 nm Py-GCMS analysis. predicted that progressively size-reduced rapidly biodegraded, indicating shorter half-life smaller plastic particles have. This study allayed concerns regarding accumulation plastic-degrading provided critical insights into factors controlling MP NP generation macroinvertebrate-mediated biodegradation.

Nano- and Microplastics Increase the Occurrence of Bacterial Wilt in Tomato (Solanum lycopersicum L.)

Concern over nano- and microplastic contamination of terrestrial ecosystems has been increasing. However, little is known about the effect microplastics on response already under biotic stress. Here, at 150–500 mg·kg–1 were exposed to tomatoes (Solanum lycopersicum L.), results demonstrate that presence increased occurrence bacterial wilt caused by Ralstonia solanacearum in as a function contaminant concentration, surface modification, size. Our work shows nanoplastics (30 nm, 250 mg·kg–1) disease incidence 2.19-fold. The severities amino- carboxyl-modified nanoplastic treatments 30.4 21.7% higher than unmodified treatment, respectively. severity influence different-sized followed order 30 > 100 nm 1 50 μm. Mechanistically, disrupted structure tomato rhizosphere soil community suppressed induced systemic resistance tomato; planta decreased salicylic acid jasmonic content tomatoes, thus inhibiting acquired resistance; water retention, leading pathogen abundance rhizosphere. Additionally, leachates from had no or growth tomatoes. findings highlight potential risk agriculture sustainability food security.

Soil Amoebae Affect Iron and Chromium Reduction through Preferential Predation between Two Metal-Reducing Bacteria

Environmental Science & Technology, Год журнала: 2022, Номер 56(12), С. 9052 - 9062

Soil protists are essential but often overlooked in soil and could impact microbially driven element cycling natural ecosystems. However, how influence heavy metal remains poorly understood. In this study, we used a model protist, Dictyostelium discoideum, to explore the effect of interactions between amoeba metal-reducing bacteria on reduction Fe(III) Cr(VI). We found that D. discoideum preferentially prey Fe(III)-reducing bacterium Shewanella decolorationis S12 significantly decrease its biomass. Surprisingly, predation pressure also stimulated activity single S. reduce by enhancing content electron-transfer protein cyt c, intracellular ATP synthesis, reactive oxygen species (e.g., H2O2). not Cr(VI)-reducing Brevibacillus laterosporus. contrast, B. laterosporus became edible amoebae presence S12, their Cr(VI) ability decreased under pressure. This study provides direct evidence can affect Cr Fe via elective bacteria, broadening our horizons cycling.
