  2. Flagellum - Wikipedia

    en.wikipedia.org/wiki/Flagellum

    The engine is powered by proton-motive force, i.e., by the flow of protons (hydrogen ions) across the bacterial cell membrane due to a concentration gradient set up by the cell's metabolism (Vibrio species have two kinds of flagella, lateral and polar, and some are driven by a sodium ion pump rather than a proton pump [26]). The rotor ...

  3. Bacterial motility - Wikipedia

    en.wikipedia.org/wiki/Bacterial_motility

    In polar flagellation, the flagella are present at one or both ends of the cell: if a single flagellum is attached at one pole, the cell is called monotrichous; if a tuft of flagella is located at one pole, the cells is lophotrichous; when flagella are present at both ends, the cell is amphitrichous.

  4. Polar organelle - Wikipedia

    en.wikipedia.org/wiki/Polar_organelle

    A polar organelle is a structure at a specialised region of the bacterial polar membrane that is associated with the flagellar apparatus. [ 1 ] [ 2 ] This flagellum-associated structure can easily be distinguished from the other membrane regions in ultrathin sections of embedded bacteria by electron microscopy when the cell membrane is ...

  5. Opisthokont - Wikipedia

    en.wikipedia.org/wiki/Opisthokont

    The opisthokonts (from Ancient Greek ὀπίσθιος (opísthios) 'rear, posterior' and κοντός (kontós) 'pole, i.e. flagellum') are a broad group of eukaryotes, including both the animal and fungus kingdoms. [5] The opisthokonts, previously called the "Fungi/Metazoa group", [6] are generally recognized as a clade.

    en.wikipedia.org/wiki/File:Flagellum_base...

    A flagellum (plural: flagella) is a long, slender projection from the cell body, whose function is to propel a unicellular or small multicellular organism. The depicted type of flagellum is found in bacteria such as E. coli and Salmonella , and rotates like a propeller when the bacterium swims.

  7. Vibrio - Wikipedia

    en.wikipedia.org/wiki/Vibrio

    Another difference is that the gradient used to power the flagellar motor is sodium driven rather than proton driven; this creates greater torque, and Vibrio flagella have been shown to rotate over five times faster than the H +-driven flagella of E. coli. The flagellum is also surrounded by a sheath extending from the membrane.

  8. Caldimonas hydrothermale - Wikipedia

    en.wikipedia.org/wiki/Caldimonas_hydrothermale

    Caldimonas hydrothermale is a Gram negative, thermophilic and motile bacterium from the genus Caldimonas with a single polar flagellum which has been isolated from a natural thermal spring in Tozeur in Tunisia. [1] [2] [3] [4]

  9. Bradyrhizobium - Wikipedia

    en.wikipedia.org/wiki/Bradyrhizobium

    Bradyrhizobium species are Gram-negative bacilli (rod-shaped) with a single subpolar or polar flagellum.They are common soil-dwelling micro-organisms that can form symbiotic relationships with leguminous plant species where they fix nitrogen in exchange for carbohydrates from the plant.
