A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
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 ...
The "typical", early-discovered Vibrio species, such as V. cholerae, have a single polar flagellum (monotrichous) with sheath. Some species, such as V. parahaemolyticus and V. alginolyticus , have both a single polar flagellum with sheath and thin flagella projecting in all directions (peritrichous), and the other species, such as V. fischeri ...
In solutions with NaCl concentrations of 0.6-1.5M, Marinobacter hydrocarbonoclasticus produce and move by the movement of “a single unsheathed polar flagellum.” [2] In solutions with NaCl concentrations <0.2 or >1.5, M. hydrocarbonoclasticus are unable to produce flagella, and are thereby unable to influence their movement through medium. [2]
It is motil by a single polar flagellum. It is named after G. L. Gilardi, an American microbiologist. [5] The organism was initially identified as Ralstonia gilardii in 1999, renamed Wautersiella gilardii, and most recently moved into the genus Cupriavidus after 16S rRNA gene sequencing revealed it to be most closely related to Cupriavidus ...
Aestuariibacter aggregatus is a gram-negative, strictly aerobic, non-spore-forming, catalase- and oxidase-positive, from the genus of Aestuariibacter with a single polar flagellum which was isolated from the Yellow Sea in China. [3] [4]
Pseudomonas proteolytica is a psychrophilic, Gram-negative, motile with a polar flagellum, rod-shaped bacterium isolated from cyanobacterial mats in Antarctica. [ 1 ] References
