Halobacteria
Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) are a class (biology), class of prokaryotic archaea under the phylum Euryarchaeota, found in water Saturated and unsaturated compounds, saturated or nearly saturated with salt. 'Halobacteria' are now recognized as archaea rather than bacteria and are one of the largest groups of archaea. The name 'halobacteria' was assigned to this group of organisms before the existence of the Domain (biology), domain Archaea was realized, and while valid according to Taxonomy (biology), taxonomic rules, should be updated. Halophilic archaea are generally referred to as haloarchaea to distinguish them from halophilic bacteria. These Halophile, halophilic microorganisms require high salt concentrations to grow, with most species requiring more than 2M NaCl for growth and survival. They are a distinct evolutionary branch of the Archaea distinguished by the possession of ether-linked lipids and the absence of murein in their ...

Methanobacteria
Methanobacteria is a class of archaeans in the kingdom Euryarchaeota Methanobacteriota is a phylum in the domain Archaea. Taxonomy The phylum ''Methanobacteriota'' was introduced to prokaryotic nomenclature in 2023. It contains following classes: *Archaeoglobi Garrity & Holt (2002) *Halobacteria Grant ''et al .... Several of the classes of the Euryarchaeota are methanogens and the Methanobacteria are one of these classes. Applications ''Methanobacteria'' can be used in biomass conversion as well as energy production through Anaerobic digestion (AD) process. Microbial community is used in Anaerobic digestion (AD) to convert organic wastes into clean energy by reducing chemical and biological oxygen demand in the wastes. Solid-state anaerobic digestion, which contains six genera of methanogens including ''Methanobacteria'', can ferment rice straw and then produce methane. Since conventional treatment is burning rice straw in field, applying ''Methanobacteria'' to waste di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermococci
Thermococci is a class of microbes within the Euryarchaeota Methanobacteriota is a phylum in the domain Archaea. Taxonomy The phylum ''Methanobacteriota'' was introduced to prokaryotic nomenclature in 2023. It contains following classes: *Archaeoglobi Garrity & Holt (2002) *Halobacteria Grant ''et al .... They live in extremely hot environments, such as hydrothermal vents, and they have optimal growth temperatures above 80 °C. '' Thermococcus'' and '' Pyrococcus'' (literally "balls of fire") are both obligately anaerobic chemoorganotrophs. ''Thermococcus'' prefers 70–95 °C and ''Pyrococcus'' 70-100 °C. '' Palaeococcus helgesonii'', recently discovered in the Tyrrhenian Sea, is an aerobic chemoheterotrophic that grows at temperatures of 45–85 °C with an optimal temperature of 80 °C. '' Thermococcus gammatolerans'' sp. nov. was recently discovered in the Guaymas Basin, and it grows at temperatures from 55 to 95 °C with an o ...

Methanopyri
Methanopyri is a class of archaea Archaea ( ) is a Domain (biology), domain of organisms.

Thermoplasmata
Thermoplasmata is a class of archaeans in the phylum Thermoplasmatota. All are acidophiles, growing optimally at pH below 2. '' Picrophilus'' is currently the most acidophilic of all known organisms growing at a minimum pH of 0.06. Many of these organisms do not contain a cell wall, although this is not true in the case of '' Picrophilus''. Most members of Thermoplasmata are thermophilic. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information The National Center for Biotechnology Information (NCBI) is part of the National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is lo ... (NCBI).

Methanobacterium Formicicum
''Methanobacterium'' is a genus of the ''Methanobacteria'' class in the Archaea kingdom, which produce methane as a metabolic byproduct. Despite the name, this genus belongs not to the bacterial domain but the archaeal domain (for instance, they lack peptidoglycan in their cell walls). ''Methanobacterium'' are nonmotile and live without oxygen, which is toxic to them, and they only inhabit anoxic environments. A shared trait by all methanogens is their ability to recycle products. They can use the products of metabolic activities occurring during methanogenesis as substrates for the formation of methane. ''Methanobacterium'' species typically thrive in environments with optimal growth temperatures ranging from 28 to 40 °C, and in versatile ecological ranges. They are a part of the scientific world that is still relatively unknown, but methanogens are thought to be some of earth's earliest life forms. They do not create endospores when nutrients are limited. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylum
In biology, a phylum (; : phyla) is a level of classification, or taxonomic rank, that is below Kingdom (biology), kingdom and above Class (biology), class. Traditionally, in botany the term division (taxonomy), division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 31 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about eight phyla. Current research in phylogenetics is uncovering the relationships among phyla within larger clades like Ecdysozoa and Embryophyta. General description The term phylum was coined in 1866 by Ernst Haeckel from the Greek (, "race, stock"), related to (, "tribe, clan"). Haeckel noted that species constantly evolved into new species that seemed to retain few consistent features among themselves and therefore few features that distinguishe ...

Archaea
Archaea ( ) is a Domain (biology), domain of organisms. Traditionally, Archaea only included its Prokaryote, prokaryotic members, but this has since been found to be paraphyletic, as eukaryotes are known to have evolved from archaea. Even though the domain Archaea Cladistics, cladistically includes eukaryotes, the term "archaea" (: archaeon , from the Greek "ἀρχαῖον", which means ancient) in English still generally refers specifically to prokaryotic members of Archaea. Archaea were initially Taxonomy (biology), classified as bacteria, receiving the name archaebacteria (, in the Archaebacteria Kingdom (biology), kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from Bacteria and Eukaryote, Eukaryota. Archaea are further divided into multiple recognized phylum, phyla. Classification is difficult because most have not been Isolation (microbiology), isolated in a laboratory and have been detected only by their Gene, gene s ...

Archaeoglobi
Archaeoglobaceae are a family of the Archaeoglobales. All known genera within the Archaeoglobaceae are hyperthermophilic and can be found near undersea hydrothermal vents. Archaeoglobaceae are the only family in the order ''Archaeoglobales'', which is the only order in the class ''Archaeoglobi''. Mode of metabolism While all genera within the Archaeoglobaceae are related to each other phylogenetically, the mode of metabolism used by each of these organisms is unique. '' Archaeoglobus'' are chemoorganotrophic sulfate-reducing archaea, the only known member of the Archaea that possesses this type of metabolism. '' Ferroglobus'', in contrast, are chemolithotrophic organisms that couple the oxidation of ferrous iron to the reduction of nitrate. '' Geoglobus'' are iron reducing-archaea that use hydrogen gas or organic compounds as energy sources. Characteristic and genera ''Archaeoglobaceae'' have three genera and here are some brief differences between them: * Archaeoglob ...
