Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Cultures are found in soil, water, sewage, feces and gut environments.
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3] Capable of motility via peritrichous flagella, [4] it is approximately one to three microns in length.
Their high numbers in plants are thought to be at least partly attributable to their lack of a flagellum, as flagella are known to induce plant defenses. [21] Additionally, K. variicola is known to associate with a number of different plants including banana trees, [22] sugarcane [23] and has been isolated from the fungal gardens of leaf-cutter ...
Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.
These bacteria have a rod shape with a typical length of 1–5 μm. Most C. freundii cells have several flagella used for locomotion, although some non-motile taxa do not. C. freundii is a soil-dwelling microorganism, but can also be found in water, sewage, food, and the intestinal tracts of animals and humans. The genus Citrobacter was ...
A spirillum (plural spirilla) is a rigid spiral bacterium that is gram-negative and frequently has external amphitrichous or lophotrichous flagella. [33] Examples include: Members of the genus Spirillum; Campylobacter species, such as Campylobacter jejuni, a foodborne pathogen that causes campylobacteriosis
P. vulneris has a rod-like (bacilli) shape, and it achieves motility using peritrichous flagella (covering the whole body of the bacteria). P. vulneris is facultatively anaerobic, and is not spore-forming. Optimal growth occurs at 35-37 °C, and it can colonize on a simple nutrient medium.
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.
