A spirochaete or spirochete is a member of the phylum Spirochaetota, which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled cells. Spirochaetes are chemoheterotrophic in nature, with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm.
Nanoarchaeota is a proposed phylum in the domain Archaea that currently has only one representative, Nanoarchaeum equitans, which was discovered in a submarine hydrothermal vent and first described in 2002.
Verrucomicrobiota is a phylum of Gram-negative bacteria that 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 from genus Xiphinema, residing in their gametes.
Corynebacterium is a genus of Gram-positive bacteria and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name.
The Thermodesulfobacteriota are a phylum of thermophilic sulfate-reducing bacteria.
Ralph Waite was an American actor, best known for his lead role as John Walton Sr. on The Waltons (1972–1981), which he occasionally directed. He later had recurring roles as two other heroic fathers; in NCIS as Jackson Gibbs, the father of Leroy Jethro Gibbs, and in Bones, as Seeley Booth's grandfather. Waite had supporting roles in movies such as Cool Hand Luke (1967), Five Easy Pieces (1970), The Grissom Gang (1971), The Bodyguard (1992), and Cliffhanger (1993).
Eustigmatophytes are a small group of eukaryotic forms of algae that includes marine, freshwater and soil-living species.
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 Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: Omma,Tetraphalerus and Beutelius. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed on deadwood.
The Isalo serotine is a vesper bat of Madagascar in the genus Laephotis. It is known only from the vicinity of the Isalo National Park in the southwestern part of the island, where it has been caught in riverine habitats. After the first specimen was caught in 1967, it was described as a subspecies of Eptesicus somalicus in 1995. After four more specimens were collected in 2002 and 2003, it was recognized as a separate species. Because of its small distribution and the threat of habitat destruction, it is considered "vulnerable" in the IUCN Red List.
Nitrospirota is a phylum of bacteria. It includes multiple genera, such as Nitrospira, the largest. The first member of this phylum, Nitrospira marina, was discovered in 1985. The second member, Nitrospira moscoviensis, was discovered in 1995.
Solidesulfovibrio magneticus is an anaerobic, Gram-negative, sulfate-reducing bacteria originally sourced from freshwater sediments in Wakayama, Japan but have also been found in the deep sea, indicating their ability to thrive in aquatic environments. S. magneticus are classified as magnetotactic bacteria with the ability to produce magnetite particles Since its discovery, further research has revealed the importance of S. magneticus and the magnetosomes they produce in the development of medical devices, reduction of nutrient-rich dead zones, and fossilization methods. Originally described under Desulfovibrio, it was reassigned to Solidesulfovibrio by Waite et al. in 2020.
The "Aigarchaeota" are a proposed archaeal phylum of which the main representative is Caldiarchaeum subterraneum. It is not yet clear if this represents a new phylum or a Nitrososphaerota order, since the genome of Caldiarchaeum subterraneum encodes several Nitrososphaerota-like features. The name "Aigarchaeota" comes from the Greek αυγή, avgí, meaning "dawn" or "aurora", for the intermediate features of hyperthermophilic and mesophilic life during the evolution of its lineage.
Geopsychrobacter is a genus of bacteria from the order Desulfuromonadales.
Pseudodesulfovibrio is a bacterium genus in the family Desulfovibrionaceae.
Fundidesulfovibrio is a bacterium genus in the family Desulfovibrionaceae.
Maridesulfovibrio is a bacterium genus in the family Desulfovibrionaceae.
Humidesulfovibrio is a bacterium genus in the family Desulfovibrionaceae.
