In the currently accepted classification of life, there are three domains Eukaryotes, Bacteria and Archaea , which, in terms of taxonomy, despite following the same principles have several different conventions between them and between their subdivisions as are studied by different disciplines botany, zoology, mycology and microbiology , for example in zoology there are type specimens, whereas in microbiology there are type strains.
Diversity Prokaryotes share many common features, such as lack of nuclear membrane, unicellularity, division.
Proteobacteria - Wikipedia
The Cardiobacteriaceae are a family of Proteobacteria, given their own order. They are Gram-negative and rod-shaped, with diameters around 0. Garrity: Bergey's Manual of Systematic Bacteriology 2. Cross section of a spirochaete cell Endoflagella Components. Legend: Fig. Periplasm, consisting of a gel-like matrix, provides a semi-stable medium to secure endoflagella during rotation. The axial filament, indicated in red, is composed of bundles of endoflagella.

One axial filament rotates in a clockwise orientation; an adjacent axial filament rotates in a counter-clockwise orientation. Rotation of the endoflagella creates torsion and drives the corkscrew rotation of the cell. Both the inner and outer membrane contain a phospholipid bi-layer, with non-polar fatty acid chains in-ward of polar phosphorus heads. Peptidoglycan, the cell wall, provides structure in bacterial microorganism.
The Bacillales are an order of Gram-positive bacteria, placed within the Firmicutes. Retrieved March 24, George M. Garrity; Vos, P.

Gram-positive cells have a thick layer of peptidoglycan in the cell wall that retains the primary stain, crystal violet. Gram-negative cells have a thinner peptidoglycan layer that allows the crystal violet to wash out. They are stained pink by the counterstain, commonly safranin or fuchsine.
The Gram stain is almost always the first step in the preliminary identification of a bacterial organism. While Gram st. The Rhizobiales are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families Bradyrhizobiaceae, Hyphomicrobiaceae, Phyllobacteriaceae, and Rhizobiaceae contain at least six genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera Bradyrhizobium and Rhizobium. Other important genera are the human pathogens Bartonella and Brucella, as well as Agrobacterium genetic engineering.

Gallego et al. The Campylobacterales are an order of Proteobacteria which make up the epsilon subdivision, together with the small family Nautiliaceae.
Like all Proteobacteria, they are Gram-negative. Most of the species are microaerophilic. Additionally, two conserved signature indels have been identified which, along with the proteins, serve as molecular markers for the order. New York, New York: Springer. Acidovorax is a genus of Proteobacteria. All species are facultative. Corynebacterium is a genus of bacteria that are Gram-positive and aerobic.
They are bacilli rod-shaped , and in some phases of life they are, more particularly, club-shaped, which inspired the genus name coryneform means "club-shaped". They are widely distributed in nature in the microbiota of animals including the human microbiota and are mostly innocuous, most commonly existing in commensal relationships with their hosts.
As with various species of a microbiota including their cousins in the genera Arcanobacterium and Trueperella , they usually are not pathogenic but can occasionally opportunistically capitalize on atypical access to tissues via wounds or weakened host defenses.
Taxonomy The genus Corynebacterium was created by Lehmann and Neumann in as a taxonomic group to contain the bacterial rods responsible for causing. The Aeromonadales are an order of Proteobacteria, with 10 genera in two families. Some species of this order are motile by a single polar flagellum; others are not motile. The Chloroflexi or Chlorobacteria 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 green non-sulfur bacteria ; and anaerobic halorespirers, which uses halogenated organics such as the toxic chlorinated ethenes and polychlorinated biphenyls as electron acceptors.
In contrast, the members of the phylum Chloroflexi are monoderms, but stain mostly Gram negative.

Berlin: Springer. They are single-celled organisms with no true nuclear membrane prokaryotic organisms. The taxon Monera was first proposed as a phylum by Ernst Haeckel in The last commonly accepted mega-classification with the taxon Monera was the five-kingdom classification system established by Robert Whittaker in Under the three-domain system of taxonomy, introduced by Carl Woese in , which reflects the evolutionary history of life, the organisms found in kingdom Monera have been divided into two domains, Archaea and Bacteria with Eukarya as the third domain.
Furthermore, the taxon Monera is paraphyletic does not include all descendants of their most-recent common ancestor , as Archaea and Eukarya are currently believed to be. Turicibacter is a genus in the Firmicutes phylum of bacteria that has most commonly been found in the guts of animals. However, it was tentatively placed in the class Bacilli, then the class Erysipelotrichia.
