Abstract

The taxonomic structure of biofilms on 0.3-mm microplastics differed significantly from that on 3-mm microplastics or glass particles. Compared with the 3-mm microplastics, biofilms on 0.3-mm microplastics were enriched for genes involved in flagellar-based motility and chemotaxis, pointing to a more 'mobile' community. The association between motility and bacterial colonization of 0.3-mm microplastics was observed through laboratory experiments using isolated strains.

摘要

0.3毫米微塑料上生物膜的分类结构与3毫米微塑料或玻璃颗粒上的生物膜分类结构有显著差异。与3毫米微塑料相比，0.3毫米微塑料上的生物膜富含参与基于鞭毛的运动和趋化作用的基因，表明其群落更具“流动性”。通过使用分离菌株的实验室实验观察到了运动性与0.3毫米微塑料上细菌定殖之间的关联。
