Reformed microplastic biofilms by ambient BPA showed limited acceleration ability in subsequent BPA degradation in natural lake water

Summary

Researchers found that bisphenol A (BPA) significantly reshaped microplastic biofilm communities and that while these reformed biofilms showed short-term acceleration of BPA degradation in natural lake water, complex interactions among microorganisms and between microorganisms and their environment constrained any sustained enhancement over time. The findings provide a foundation for assessing the environmental risk posed by the co-occurrence of bisphenol compounds and microplastics in aquatic systems.
