Summary

Researchers found that early-stage biofilm assembly on microplastics is strongly influenced by substrate size, with 0.3-mm particles harboring distinct bacterial communities enriched in motility and chemotaxis genes compared to larger 3-mm microplastics.

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.
