Researchers investigated seasonal biofilm formation on floating polyethylene and polypropylene microplastics in four coastal mariculture zones in southeast China, finding that biofilm bacterial community composition differed less between winter and summer than the surrounding planktonic bacteria. The results suggest biofilms on microplastics provide a buffering microenvironment that stabilizes bacterial communities across seasons.
Community composition and seasonal dynamics of microplastic biota in the Eastern Mediterranean Sea
Scientists studied the microbial communities living on microplastics in the Eastern Mediterranean Sea across all four seasons over two years. They found that microplastics host a distinct and relatively stable community of bacteria and other organisms that differs from the surrounding seawater. This "plastisphere" ecosystem could serve as a vehicle for transporting potentially harmful microorganisms across ocean environments.
