Rhodobacterales are an order of the Alphaproteobacteria. [2]

Contents

Gene transfer agents are viruslike elements produced by Rhodobacterales which transfer DNA and may be an important factor in their evolution. [3]

Etymology

From Greek rhodon, the rose, and bakterion, a rod. This refers to the colour of aerobic phototrophic cultures of this order of bacteria which can be pink or red due to the production of carotenoids. [4]

The Aquificota phylum is a diverse collection of bacteria that live in harsh environmental settings. The name Aquificota was given to this phylum based on an early genus identified within this group, Aquifex, which is able to produce water by oxidizing hydrogen. They have been found in springs, pools, and oceans. They are autotrophs, and are the primary carbon fixers in their environments. These bacteria are Gram-negative, non-spore-forming rods. They are true bacteria as opposed to the other inhabitants of extreme environments, the Archaea.

<span class="mw-page-title-main">Deinococcota</span> Phylum of Gram-negative bacteria

Deinococcota is a phylum of bacteria with a single class, Deinococci, that are highly resistant to environmental hazards, also known as extremophiles. These bacteria have thick cell walls that give them gram-positive stains, but they include a second membrane and so are closer in structure to those of gram-negative bacteria.

The Thermoprotei is a class of the Thermoproteota.

Mollicutes is a class of bacteria distinguished by the absence of a cell wall. The word "Mollicutes" is derived from the Latin mollis, and cutis. Individuals are very small, typically only 0.2–0.3 μm in size and have a very small genome size. They vary in form, although most have sterols that make the cell membrane somewhat more rigid. Many are able to move about through gliding, but members of the genus Spiroplasma are helical and move by twisting. The best-known genus in the Mollicutes is Mycoplasma. Colonies show the typical "fried-egg" appearance.

In taxonomy, the Methanopyri are a class of the Euryarchaeota.

The Myxococcota are a phylum of bacteria known as the fruiting gliding bacteria. All species of this group are Gram-negative. They are predominantly aerobic genera that release myxospores in unfavorable environments.

<span class="mw-page-title-main">Methanococci</span> Class of archaea

Methanococci is a class of methanogenic archaea in the phylum Euryarchaeota. They can be mesophilic, thermophilic or hyperthermophilic.

Acidilobales are an order of archaea in the class Thermoprotei.

<span class="mw-page-title-main">Desulfurococcales</span> Order of archaea

The Desulfurococcales is an order of the Thermoprotei, part of the kingdom Archaea. The order encompasses some genera which are all thermophilic, autotrophs which utilise chemical energy, typically by reducing sulfur compounds using hydrogen. Desulfurococcales cells are either regular or irregular coccus in shape, with forms of either discs or dishes. These cells can be single, in pairs, in short chains, or in aciniform formation.

In taxonomy, the Methanococcales are an order of the Methanococci.

Sulfolobales is an order of archaeans in the class Thermoprotei.

<span class="mw-page-title-main">Thermococcales</span> Order of archaea

In taxonomy, the Thermococcales are an order of microbes within the Thermococci. The species within the Thermococcales are used in laboratories as model organisms. All these species are strict anaerobes and can ferment sugars as sources of carbon, but they also need elemental sulfur.

In taxonomy, the Methanosaetaceae are a family of microbes within the order Methanosarcinales. All species within this family use acetate as their sole source of energy.

In taxonomy, the Methanosarcinaceae are a family of the Methanosarcinales.

In taxonomy, Oceanicola is a genus of the Rhodobacteraceae.

The Negativicutes are a class of bacteria in the phylum Bacillota, whose members have a peculiar cell wall with a lipopolysaccharide outer membrane which stains gram-negative, unlike most other members of the Bacillota. Although several neighbouring Clostridia species also stain gram-negative, the proteins responsible for the unusual diderm structure of the Negativicutes may have actually been laterally acquired from Pseudomonadota. Additional research is required to confirm the origin of the diderm cell envelope in the Negativicutes.

Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.

Solirubrobacter is a Gram-positive, spore-forming, aerobic, mesophilic and non-motile genus of bacteria from the family Solirubrobacteraceae.

Catenulispora is a Gram-positive, rod-shaped and aerobic genus of bacteria.
