Alcaligenes
''Alcaligenes'' is a genus of Gram-negative, aerobic, rod-shaped bacteria. The species are motile with amphitrichous flagella and rarely nonmotile. It is a genus of non-fermenting bacteria (in the family Alcaligenaceae). Additionally, some strains of ''Alcaligenes'' are capable of anaerobic respiration, but they must be in the presence of nitrate or nitrite; otherwise, their metabolism is respiratory and never fermentative; The genus does not use carbohydrates. Strains of ''Alcaligene''s (such as ''A. faecalis'') are found mostly in the intestinal tracts of vertebrates, decaying materials, dairy products, water, and soil; they can be isolated from human respiratory and gastrointestinal tracts and wounds in hospitalized patients with compromised immune systems. They are occasionally the cause of opportunistic infections, including nosocomial sepsis. ''Alcaligenes faecalis'' causes nosocomial sepsis, arising from contaminated hemodialysis or intravenous fluid, in immunocompromi ...

Alcaligenes Faecalis
''Alcaligenes faecalis'' is a species of Gram-negative, rod-shaped bacteria commonly found in the environment. It was originally named for its first discovery in feces, but was later found to be common in soil, water, and environments in association with humans. While opportunistic infections do occur, the bacterium is generally considered nonpathogenic. When an opportunistic infection does occur, it is usually observed in the form of a urinary tract infection. ''A. faecalis'' has been used for the production of nonstandard amino acids. Description ''A. faecalis'' is a Gram-negative bacterium which appears rod-shaped and motile under a microscope. It is positive by the oxidase test and catalase test, but negative by the nitrate reductase test. It is alpha-hemolytic and requires oxygen. ''A. faecalis'' can be grown at 37 °C, and forms colonies that lack pigmentation. Metabolism The bacterium degrades urea, creating ammonia which increases the pH of the environment. Alt ...

Cupriavidus Metallidurans
''Cupriavidus metallidurans'' is a non-spore-forming, Gram-negative bacterium which is adapted to survive several forms of heavy metal stress. As a model and industrial system It is an ideal subject to study heavy metal disturbance of cellular processes. This bacterium shows a unique combination of advantages not present in this form in other bacteria. * Its genome (strain CH34) has been fully sequenced (preliminary, annotated sequence data were obtained from the DOE Joint Genome Institute) * It is not pathogenic, therefore, models of the cell can also be tested in artificial environments similar to its natural habitats. * It is related to the plant pathogen '' Ralstonia solanacearum''. * It is of ecological importance since related bacteria are predominant in mesophilic heavy metal-contaminated environments. * It is of industrial importance and used for heavy metal remediation and sensing. * It is an aerobic chemolithoautotroph, facultatively able to grow in a mineral ...

Flagella
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have from one to many flagella. A gram-negative bacterium '' Helicobacter pylori'' for example uses its multiple flagella to propel itself through the mucus lining to reach the stomach epithelium, where it may cause a gastric ulcer to develop. In some bacteria the flagellum can also function as a sensory organelle, being sensitive to wetness outside the cell. Across the three domains of Bacteria, Archaea, and Eukaryota the flagellum has a different structure, protein composition, and mechanism of propulsion but shares the same function of providing motility. The Latin word means " whip" to describe its lash-like swimming motion. The flagellum in archaea is called the archaellum to note its difference from the bacterial flagellum. Eukaryotic ...

Non-fermenter
Non-fermenters (also non-fermenting bacteria) are a taxonomically heterogeneous group of bacteria of the phylum Pseudomonadota that cannot Catabolism, catabolize glucose, and are thus unable to fermentation (biochemistry), ferment. This does not necessarily exclude that species can catabolize other sugars or have anaerobiosis like fermenting bacteria. The coccoid or bacillary bacteria can be found in soil or wet areas. They are non-spore, sporulating bacteria and Gram-negative bacteria, Gram-negative. Some species are also pathogenic for humans, so their detection (e.g. with analytical profile index 20 NE) has great relevance in the diagnosis of bacterial infections. List of non-fermenters * ''Acinetobacter'' * ''Alcaligenes'' * ''Bordetella'' * ''Burkholderia'' * ''Legionella'' * ''Moraxella'' * ''Pseudomonas'' *''Shewanella'' * ''Stenotrophomonas'' Also, pathogenic species include ''Pseudomonas aeruginosa'' and ''Moraxella catarrhalis''.

Achromobacter Xylosoxidans
''Achromobacter xylosoxidans'' (formerly ''Alcaligenes xylosoxidans'') is a Gram-negative, aerobic, oxidase and catalase-positive, motile bacterium with peritrichous flagella, from the genus '' Achromobacter''. It is generally found in wet environments. ''Achromobacter xylosoxidans'' can cause infections such as bacteremia, especially in patients with cystic fibrosis. In 2013, the complete genome of an ''A. xylosoxidans'' strain from a patient with cystic fibrosis was sequenced. Bacteriology ''A. xylosoxidans'' is a Gram-negative rod that does not form spores. It is motile, with peritrichous flagella that distinguish it from ''Pseudomonas'' species, and is oxidase-positive, catalase-positive, and citrate-positive. It is urease and indole-negative. It produces acid oxidatively from xylose, but not from lactose, maltose, mannitol, or sucrose. It grows well on MacConkey agar and other inhibitory growth media such as deoxycholate, Salmonella-Shigella, and nalidixic acid-cetrimide ...
