Summary

Bacterial communities colonizing plastic debris in the Haihe Estuary of Bohai Bay, China, were shaped by both environmental factors (season, salinity, temperature) and the type of plastic polymer, with distinct microbial assemblages forming on different plastic surfaces. The results demonstrate that the "plastisphere" in estuarine environments is a dynamically structured microbial habitat.

The colonization characteristics of bacterial communities on microplastics or plastic debris (PD) have generated great concern in recent years. However, the influence of environmental factors and polymer types on the formation of bacterial communities on PD in estuarine areas is less studied. To gain additional insights, five types of PD (polyvinyl chloride, polypropylene, polyethylene, polystyrene, and polyurethane) were exposed for three-time periods (two weeks, four weeks, and six weeks) in the Haihe Estuary. 16S rRNA gene sequencing was used to identify the bacterial communities on PD, in seawater, and in sediment samples. The results indicate that the average growth rate of a biofilm is affected by nutrients (total nitrogen and total phosphorus) and salinity. Furthermore, salinity is the primary factor affecting bacterial diversity of the colonies on PD. In addition, genera of bacteria show selectivity toward the PD polymer type and tend to colonize their preferred substrate. Compared with seawater and sediment, PD could be carriers for enrichment of <i>Vibrio</i> in the estuarine environment with salinity ≥26 (± 2‰), which might increase the ecological risk of PD in marine environments.
