Colonization of microplastics by cyanobacteria and its impact on marine ecosystems
In recent years,the continuous accumulation of microplastics in the ocean has raised concerns regarding the functionality and biodiversity of marine ecosystems,including the impact of cyanobacterial colonization on microplastics.The colonization of microplastics by cyanobacteria has diverse effects on cyanobacterial growth,morphology,photosynthesis,and fatty acid production.Concurrently,cyanobacterial colonization alters the physicochemical properties of microplastics,exhibiting characteristics such as degradation or the retardation of photoaging processes.The interaction between cyanobacteria and microplastics,facilitated through colonization,not only influences the primary productivity of marine ecosystems but also extends its impact throughout the entire marine ecosystem via successive trophic levels in the food chain.This review provides an overview of the current research status on cyanobacterial colonization of microplastics in marine ecosystems.It emphasizes the need for further research to better comprehend the potential impacts of cyanobacterial colonization on both the organisms involved and the entire ecosystem.Such understanding is crucial for the development of effective conservation measures and management strategies,providing a scientific foundation for future initiatives.
