Metabolic activity controls the emergence of coherent flows in microbial suspensions
Alexandros A. Fragkopoulos, Florian Böhme, Nicole Drewes +1
Photosynthetic microbes have evolved and successfully adapted to the ever-changing environmental conditions in complex microhabitats throughout almost all ecosystems on Earth. In t…
Light-regulated adsorption and desorption of Chlamydomonas cells at surfaces
Rodrigo E. Catalan, Alexandros A. Fragkopoulos, Nicolas von Trott +4
Microbial colonization of surfaces represents the first step towards biofilm formation, which is a recurring phenomenon in nature with beneficial and detrimental implications in te…
Quantifying gliding forces of filamentous cyanobacteria by self-buckling
Maximilian Kurjahn, Antaran Deka, Antoine Girot +5
Filamentous cyanobacteria are one of the oldest and today still most abundant lifeforms on earth, with manifold implications in ecology and economics. Their flexible filaments, oft…
Motility and self-organization of gliding Chlamydomonas populations
Sebastian Till, Florian Ebmeier, Alexandros A. Fragkopoulos +2
Cellular appendages such as cilia and flagella represent universal tools enabling cells and microbes, among other essential functionalities, to propel themselves in diverse environ…
Light controls motility and phase separation of photosynthetic microbes
Alexandros A. Fragkopoulos, Jérémy Vachier, Johannes Frey +4
Large ensembles of interacting, out-of-equilibrium agents are a paradigm of active matter. Their constituents' intrinsic activity may entail the spontaneous separation into localiz…
Curvature-guided motility of microalgae in geometric confinement
Tanya Ostapenko, Fabian Jan Schwarzendahl, Thomas Böddeker +4
Microorganisms, such as bacteria and microalgae, often live in habitats consisting of a liquid phase and a plethora of interfaces. The precise ways in which these motile microbes b…
