The biodegradable (polybutylene adipate terephthalate: PBAT) and conventional (polyethylene: PE) microplastics (MPs) at 0.5 %, 1 2 % dosages (w/w) were added into soils with without Serratia marcescens ZY01 (ZY01, a tet-host strain) to understand their different effects on the dissipation of oxytetracycline (OTC) tet. results showed that PBAT MP exhibited inhibition degrees OTC biodegradation in regardless ZY01, while PE did not change enhancement degree ZY01. These differences due higher adsorption capacity stronger toxicity microorganisms. Besides soil organic matter, pH total phosphorus important factors regulating specific bacteria MPs (e.g., nitrogen-cycling Steroidobacter Nitrospira) + phosphorus-cycling Saccharimonadales Haliangium), respectively. Regardless selective harboring treatments than was observed dosage (w/w), opposite trend true (w/w). Some genera belonging Actinobacteriota strongly associated class integron-integrase gene (intI1), playing critical role horizontal transfer tet especially for co-existence This study will be helpful understanding how as hotspots affect environmental behavior antibiotics ARGs soil.

Reducing risks of antibiotics to crop production requires land system intensification within thresholds

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Сен. 29, 2023

Abstract Land system intensification has substantially enhanced crop production; however, it also created soil antibiotic pollution, undermining production. Here, we projected pollution risks to production at multiple geographical scales in China and linked them land (including arable expansion input increase). Our projections suggest that will decrease when the risk quotient exceeds 8.30–9.98. systems explain most of variability (21–66%) across spatial scales. The convex nonlinearities tradeoffs between indicate vegetable wheat have higher thresholds which risk–yield peak than do maize rice study suggests below minimum is required for acceptable related yield reduction.
