Verrucomicrobia is a phylum of bacteria. This phylum contains only a few described species. The species identified have been isolated from fresh water, marine and soil environments and human faeces. A number of as-yet uncultivated species have been identified in association with eukaryotic hosts including extrusive explosive ectosymbionts of protists and endosymbionts of nematodes residing in their gametes. While verrucae is another name for the warts often found on hands and feet, this phylum is so called not because it is a causative agent thereof, but because of its wart-like morphology.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcus–Thermus group. It includes the following species:
The Rhizobiales are an order of Gram-negative Alphaproteobacteria.
Halomonadaceae is a family of halophilic Proteobacteria.
The Thermotogae are a phylum of the domain Bacteria. The phylum Thermotogae is composed of Gram-negative staining, anaerobic, and mostly thermophilic and hyperthermophilic bacteria.
Sinorhizobium/Ensifer is a genus of nitrogen-fixing bacteria (rhizobia), three of which have been sequenced.
The Synergistetes is a recently recognized phylum of anaerobic bacteria that show Gram-negative staining and have rod/vibrioid cell shape. Although Synergistetes have a diderm cell envelope, the genes for various proteins involved in lipopolysaccharides biosynthesis have not yet been detected in Synergistetes, indicating that they may have an atypical outer cell envelope. The Synergistetes inhabit a majority of anaerobic environments including animal gastrointestinal tracts, soil, oil wells, and wastewater treatment plants and they are also present in sites of human diseases such as cysts, abscesses, and areas of periodontal disease. Due to their presence at illness related sites, the Synergistetes are suggested to be opportunistic pathogens but they can also be found in healthy individuals in the microbiome of the umbilicus and in normal vaginal flora. Species within this phylum have also been implicated in periodontal disease, gastrointestinal infections and soft tissue infections. Other species from this phylum have been identified as significant contributors in the degradation of sludge for production of biogas in anaerobic digesters and are potential candidates for use in renewable energy production through their production of hydrogen gas. All of the known Synergistetes species and genera are presently part of a single class (Synergistia), order (Synergistiales) and family (Synergistaceae).
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 ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Deinococcus is one genus of three in the order Deinococcales of the bacterial phylum Deinococcus-Thermus highly resistant to environmental hazards. 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 Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria.
Actinopolymorpha is a genus in the phylum Actinobacteria (Bacteria).
Aidingimonas is a genus in the phylum Proteobacteria (Bacteria).
Armatimonadetes is a phylum of gram-negative bacteria.
Jeotgalicoccus halophilus is a species of bacteria. It is one of the Phylum Firmicutes, it is Gram-positive. The species is halotolerant, it grows at NaCl content of 0.1 to 16% and optimal values are between 2 and 3%. The cells are coccoid.
Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
Alicyclobacillus aeris is a species of Gram positive/Gram variable, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from a copper mine in Inner Mongolia, China. The species was first described in 2009, and the name is derived from the Latin aeris.
Fodinibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are strictly aerobic and mesophilic. Cells of the genus are irregular rods and grow very poorly in the absence of NaCl. The genus name is derived from Latin fodina (mine), referring to the salt mine from which the type species was isolated.
Humibacillus is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are strictly aerobic and mesophilic. Cells of the genus are irregular rods. The genus name is derived from Latin humus (soil).
Lapillicoccus jejuensis is a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are coccoid. The species was first described in 2007, and it was originally isolated a stone in Jeju, South Korea. The species name refers to the area (Jeju) from which it was first isolated. L. jejuensis is the type species of genus Lapillicoccus, and is currently the only species in the genus.
Marihabitans asiaticum is a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are irregular rods or coccoid. The species was first described in 2008, and it was originally isolated in 2003 from surface seawater collected at the Kesennuma ferry port in Miyagi Prefecture, Japan. The species name refers to the region (Asia) from which it was first isolated. M. asiaticum is the type species of genus Marihabitans, and is currently the only species in the genus.
Ornithinibacter aureus is a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are irregular rods that form branching hyphae. The species was first described in 2011, and it was originally isolated from surface seawater collected from the South China Sea. The species name is derived from Latin aureus (golden), referring to the yellow-pigmented colonies that form on R2A agar. O. aureus is the type species of genus Ornithinibacter, and is currently the only species in the genus.
