  • 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

  • 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
  • What does a high quantity of stalked ciliates (Protozoa) observed in . . .
    Members of this group of protozoa have stalks with which they attach to floc particles or other surfaces These stalks render the organism sessile for the most part With their rings of cilia
