Surface-programmed microbiome assembly in phycosphere to microplastics contamination
Researchers studied how algal-bacterial communities assemble on microplastic surfaces and their potential role in degrading these pollutants. They found that microplastics in wastewater environments develop distinct microbial communities on their surfaces, with certain bacteria showing enhanced plastic-degrading enzyme activity when associated with algae. The study suggests that engineered algal-bacterial systems could offer a sustainable biological approach to microplastic remediation.
