Caption: Epistylis ciliates. Light microscopy footage of specimens of the ciliate protozoan Epistylis, obtained from activated sludge. Epistylis is a genus of sessile single-celled protozoans, with a long stalk and a flattened head. At the top of the head is the mouth, surrounded by many fine cilia hairs. These create a vortex in the surrounding water, washing food particles into the mouth. Activated sludge is the term for a process that treats sewage and industrial waste water using bacteria and protozoa. This clip was filmed with darkfield illumination.
