Summary

Researchers investigated the effects of poly(butylene adipate-co-terephthalate) (PBAT) microplastics on Arabidopsis thaliana growth and root-associated microbiome composition in agricultural soil, at a concentration of 2% by weight. Results revealed negative effects on plant growth and alterations to the rhizosphere microbial community, raising concerns about the ecological safety of this widely used biodegradable mulch film material.

Poly(butylene adipate-co-terephthalate) (PBAT) is a biodegradable polymer that is widely used in the production of biodegradable mulch films in order to reduce the white pollution caused by non-biodegradable polyethylene mulch. Despite its widespread use in agriculture, the effects of PBAT microplastics (PBAT-MPs) on plant growth and microbial communities have rarely been reported. In this study, Arabidopsis thaliana were planted as model crop in soil containing 2 Also see: https://micro2024.sciencesconf.org/558926/document
