Halomonadaceae is a family of halophilic Pseudomonadota.
The Clostridiaceae are a family of the bacterial class Clostridia, and contain the genus Clostridium.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.
The Chloroflexota are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Enterocloster clostridioformis, formerly known as Clostridium clostridioforme, is an anaerobic, motile, Gram-positive bacterium.
Ruminococcus is a genus of bacteria in the class Clostridia. They are anaerobic, Gram-positive gut microbes. One or more species in this genus are found in significant numbers in the human gut microbiota. The type species is R. flavefaciens. As usual, bacteria taxonomy is in flux, with Clostridia being paraphyletic, and some erroneous members of Ruminococcus being reassigned to a new genus Blautia on the basis of 16S rRNA gene sequences.
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Thermoanaerobacter brockii, formerly Thermoanaerobium brockii, is a thermophilic, anaerobic, spore-forming bacterium.
Thermoanaerobacter kivui is a thermophilic, anaerobic, nonspore-forming species of bacteria.
Thermoanaerobacter pseudethanolicus is a thermophilic, strictly anaerobic, spore-forming bacteria that was first found at Yellowstone National Park in the United States. Because of its ability to efficiently ferment sugars, it is thought to be of potential use in producing industrial alcohol.
Sutterella is a genus of Gram-negative, rod-shaped, non-spore-forming, Betaproteobacteria whose species have been isolated from the human gastrointestinal tract as well as canine feces. The genus of the family Sutterellaceae currently encompasses 4 distinct species, though at least 5 additional species have been proposed that do not yet meet International Code of Nomenclature of Prokaryotes (ICNP) standards for classification. Sutterella are frequently referred to as commensal in the context of human hosts, but are associated with inflammation, which has implications for a number of diseases.
Clostridium leptum is a bacterium species in the genus Clostridium.
Clostridioides difficile is a bacterium that is well known for causing serious diarrheal infections, and may also cause colon cancer. Also known as C. difficile, or C. diff, is Gram-positive species of spore-forming bacteria. Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the microscope, they appear as long, irregular cells with a bulge at their terminal ends. Under Gram staining, C. difficile cells are Gram-positive and show optimum growth on blood agar at human body temperatures in the absence of oxygen. C. difficile is catalase- and superoxide dismutase-negative, and produces up to three types of toxins: enterotoxin A, cytotoxin B and Clostridioides difficile transferase (CDT). Under stress conditions, the bacteria produce spores that are able to tolerate extreme conditions that the active bacteria cannot tolerate.
Enterocloster aldensis, formerly Clostridium aldenense, is a bacterium in the genus Enterocloster. The type species was isolated from clinical infections in California in the United States along E. citroniae and placed in the genus Clostridium. Together with other gram-negative species, it was moved to the new genus Enterocloster in 2020. The name pertains to R. M. Alden Research Laboratory and its first patron, Rose M. Alden Goldstein.
Lacrimispora amygdalinum is a Gram-positive, anaerobic and rod-shaped bacterium from the genus Lacrimispora which has been isolated from sludge from a wastewater treatment plant in the Netherlands.
Caldibacillus is a facultative anaerobe genus of bacteria that stains Gram-positive from the family of Bacillaceae. The type species of this genus is Caldibacillus debilis.
Maledivibacter is a bacterial genus from the family of Clostridiaceae with one known species. Clostridium halophilum has been reclassified to Maledivibacter halophilus.
Wukongibacter is a Gram-positive, spore-forming, rod-shaped, anaerobic and non-motile genus of bacteria from the family of Peptostreptococcaceae with one known species.
