Summary

Bacterial communities colonizing microplastics in Haihe Estuary sediments and water were found to differ substantially from ambient environmental communities, with microplastics selecting for distinct bacterial assemblages including potential pathogens. This confirms that microplastics create ecological niches that alter microbial ecology in estuarine environments.

Study Type Environmental

The bacterial communities on microplastics in marine and freshwater environments have been described by many studies. However, the migration and transportation processes of bacterial communities on microplastics in estuarine areas remain unclear. In this study, the bacterial communities on three substrates (microplastics, surface water and sediment) in estuarine areas (the Haihe Estuary (HHE) in Bohai Bay, China) were investigated based on 16S rRNA sequencing. The mean OTUs of the three substrates - water, microplastics and sediments - were 1091, 2213 and 3419, respectively. The partitioning of the OTUs among the three substrates indicated that the microplastics could be messengers facilitating the bacterial transportation between water and sediment. According to nMDS and relative abundance analyses, it was found that the microplastics enriched the particular bacteria (e.g., Halobacteriaceae and Pseudoalteromonadaceae) and weakened the influence of environmental variation. In addition, taxonomic and metabolic-pathway analyses indicated that the abundance of potentially pathogenic bacteria (e.g., Pseudomonas and Bacillus) on microplastics was significantly higher than that in the ambient environment. Meanwhile, the microplastic polymer types had little effect on the abundance and structure of the bacterial communities. Compared with surface water and sediments, microplastics could be a good habitat for bacterial communities and could lead to potential ecological risks because of the high stability, pathogenicity and stress tolerance of the bacterial communities on microplastics.
