| contents | Hydrophobins from mediate fungal interactions with microplastics. Klauer, Ross R Silvestri, Rachel White, Hanna Hayes, Richard D Riley, Robert Lipzen, Anna Barry, Kerrie Grigoriev, Igor V Talag, Jayson Bunting, Victoria Stevenson, Zachary Solomon, Kevin V Blenner, Mark Microplastics present myriad ecological and human health risks including serving as a vector for pathogens in human and animal food chains. However, the specific mechanisms by which pathogenic fungi colonize these microplastics have yet to be explored. In this work, we examine the opportunistic fungal pathogen, and other common soil and marine , which we found bind microplastics tightly. Up to 3.85+/- 1.48 g microplastic plastic/g fungi were bound and flocculated for polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET) powders and particles ranging in size from 0.05 - 5 mm. Gene knockouts revealed hydrophobins as a key biomolecule driving microplastic-fungi binding. Moreover, purified hydrophobins were still able to flocculate microplastics independent of the fungus. Our work elucidates a role for hydrophobins in fungal colonization of microplastics and highlights a potential target for mitigating the harm of microplastics through engineered fungal-microplastic interactions. |
