Biochar immobilized hydrolase degrades PET microplastics and alleviates the disturbance of soil microbial function via modulating nitrogen and phosphorus cycles

Microplastics (MPs) are ubiquitous in soil and poses an emerging threat to soil ecological function. However, the underlying solution have been underexplored. This study emphasized the complete degradation of soil PET-MPs facilitated by biochar immobilized PET hydrolase and soil microbes, and advances our understanding the response of microbiome and functional genes to the disturbance of PET-MPs and MB-LCC-FDS in soil systems.
