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 ...
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 ...
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.
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]
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.
Pseudomonas proteolytica is a psychrophilic, Gram-negative, motile with a polar flagellum, rod-shaped bacterium isolated from cyanobacterial mats in Antarctica. [ 1 ] References
The cells are rods [2] and it has one polar flagellum. It is aerobic. References External links. Sphingomonas adhaesiva". The Encyclopedia of Life. Type strain ...
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.
