Abstract

Earthworm is an important part of the soil ecosystem. Study on the responses of earthworm gut bacteria to microplastics (MPs) is still lacking. In this work, the effects on non-biodegradable polyethylene (PE) and biodegradable poly (butylene adipate-co-terephthalate) (PBAT) MPs on bacterial community of earthworm gut were investigated. The results showed that the number of operational Taxonomic Units (OTUs) and a diversity indexes in treatments with MPs were higher than those in treatment without MPs. The number of OTUs was in the order of treatments with aged-PE MPs > treatments with unaged-PE MPs > treatments with PBAT MPs. The number of OTUs in treatments with lower MPs concentration was higher than that in treatments with higher MPs concentration. Addition of MPs increased the relative abundances of genera Ensifer, Bacteroides and Bacillus, but decreased the relative abundances of genera Salmonella, EscherichiaShigella and Paracoccus. Therefore, MPs significantly impact the microbial community of earthworm gut, which is related to types of MPs.
