Vortex generated by cilia beating of Vorticella

Vorticella is a suspension-feeding ciliate and has drawn the attention of scientists since Anthony van Leeuwenhoek first described its unique motility. Biological motors of microorganisms can be mimicked in microsystems to reduce the overall size of devices. Cilia beating has been envisaged as a potential strategy for inducing fluid flow and mixing in microsystems. The vortex generated by Vorticella was observed under foldscope, one can also notice the stalk contraction of Vorticella. I can speculate that these vortex movements also help the mixing and nutrients in the water bodies, and which ultimately help the bacterial growth. So it seems a perfect example of the domestication of bacteria, for food by the Vorticella.
