In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall.
Acetobacter is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus Acetobacter is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus Acetobacter have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures.
The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
The Hyphomicrobiales are an order of Gram-negative Alphaproteobacteria.
The Hyphomicrobiaceae are a family of bacteria. Among others, they include Rhodomicrobium, a genus of purple bacteria.
The Burkholderiaceae are a family of bacteria included in the order Burkholderiales. It includes some pathogenic species, such as Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis).
Halomonadaceae is a family of halophilic Pseudomonadota.
Campylobacterota are a phylum of bacteria. All species of this phylum are Gram-negative.
Alteromonas is a genus of Pseudomonadota found in sea water, either in the open ocean or in the coast. It is Gram-negative. Its cells are curved rods with a single polar flagellum.
Rhinonicteris is a genus of leaf-nosed microbats, represented by fossil taxa found at Riverleigh in Queensland and the extant species Rhinonicteris aurantia, which occurs in the north and west of the Australian continent.
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.
The citrate test detects the ability of an organism to use citrate as the sole source of carbon and energy.
Life form is an entity that is living, such as plants (flora) and animals (fauna). It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, are extinct.
Polynucleobacter is a genus of bacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus Euplotes.
Psychrobacter is a genus of Gram-negative, osmotolerant, oxidase-positive, psychrophilic or psychrotolerant, aerobic bacteria which belong to the family Moraxellaceae and the class Gammaproteobacteria. The shape is typically cocci or coccobacilli. Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis. This genus of bacteria is able to grow at temperatures between −10 and 42 °C. Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae. The first species was described by Juni and Heym. Psychrobacter occur in wide range of moist, cold saline habitats, but they also occur in warm and slightly saline habitats.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Bacillota. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Bizionia is a strictly aerobic genus from the family of Flavobacteriaceae which produce carotenoids. Bizionia is named after Bartolomeo Bizio.
Kushneria aurantia is a Gram-negative, aerobic, non-spore-forming, rod-shaped and moderately halophilic bacterium from the genus of Kushneria which has been isolated from the surface of leaves from the mangrove Avicennia germinans.
Enterococcus aquimarinus is a bacteria discovered in Italy, by Pavel Svec et.al in 2005. It was originated in sea water and analysed in a specific type of taxonomic study called polyphasic. It is a bacteria that can handle high temperatures, it is gram-positive, rod-shaped, and aerobic. The type strain is LMG 16607T and 16612.
Xanthovirga is a genus from the family of Flammeovirgaceae with one known species. Xanthovirga aplysinae has been isolated from the sponge Aplysina fistularis from the coast of San Salvador.
