Filamentous cyanobacteria are highly relevant in global ecology, ranging from our fossil oil record to rampant and frequently toxic algal blooms in freshwater lakes. They form multi-cellular trichomes in which a few tens to several hundreds of cells are linearly stacked. In contact with solid surfaces, several genera exhibit gliding motility, propelling themselves along the filament contour. This project aims at understanding the emergent collective behavior of such ‘active polymers’, based on experiments in both idealized (2D) and realistic (3D/porous) environments. We expect that our findings will have implications also in Bioreactor technology, for which filamentous cyanobacteria have recently gained great attention.
