Stalked Ciliates - Environmental Leverage Stalked ciliates are "inverted bell-shaped bodies mounted on a stalk which is attached to a substratum " A key identification feature is the presence of cilia (minute hair-like projections) on the oral region of the organism
Stalked Ciliate - Aquafix Stalked ciliates are one of the most important protozoa in a wastewater system for aiding in clear effluent There are two different distinct types of stalked ciliates: those with a shell, or a lorica, and those without
Ciliate - Wikipedia The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella
Wastewater Treatment Organism Identification - Microscope World Stalk ciliates and suctorians (see below) are the ideal indicator protozoa for most wastewater systems Present only in systems with good dissolved oxygen (DO), low soluble organics, and good floc forming conditions, stalk forms do not move and are easy to observe
Stalked Ciliate-Wastewater Bug Spotlight - Santa Barbara, California Stalked ciliates attach to sludge or other clumped bacteria and use their cilia to create a water vortex around their mouth This vortex allows the ciliate to filter feed on the bacteria-rich wastewater, aiding in wastewater treatment Stalked ciliates can grow individually or in colonies
Microbiology Gallery - EBS Stalked ciliates usually indicate a stable, healthy system with a moderate to high maturity index Because stalked ciliates attach to pieces of floc, they usually imply that the biomass (bacteria) is forming well-structured floc that is essential to settling and good effluent quality
Lesson 6: Protozoa - Mountain Empire Community College The three types of ciliated protozoa are free-swimming ciliates, crawling ciliates, and stalked ciliates All of these have short hair-like structures or cilia that beat in unison to produce a water current for locomotion and capturing bacteria Ciliates feed on bacteria, not on dissolved organics
Filamentous Bacteria and Stalked Ciliates for the Stable Structure of . . . Stalked ciliates are inverted bell-shaped bodies mounted on a stalk which is attached to a substratum Epistylis is one genera of stalked ciliates seen commonly in activated sludge for wastewater treatment Stalked ciliates are usually an indication of a stable activated sludge operation
