Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteroidota
The phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals. Although some ''Bacteroides'' spp. can be opportunistic pathogens, many ''Bacteroidota'' are symbiotic species highly adjusted to the gastrointestinal tract. ''Bacteroides'' are highly abundant in intestines, reaching up to 1011 cells g−1 of intestinal material. They perform metabolic conversions that are essential for the host, such as degradation of proteins or complex sugar polymers. ''Bacteroidota'' colonize the gastrointestinal tract already in infants, as non-digestible oligosaccharides in mother milk support the growth of both '' Bacteroides'' and '' Bifidobacterium'' spp. ''Bacteroides'' spp. are selectively recognized by the immune system of the host through specif ...

Flavobacteriia
The class Flavobacteriia is composed of a single order of environmental bacteria. According to Bernardet ''et al''., Flavobacteriia are Gram-negative aerobic rods, 2–5 μm long, 0.3–0.5 μm wide, with rounded or tapered ends that are motile by gliding, yellow (cream to orange) colonies on agar, decompose several polysaccharides but not cellulose, G+C contents of 32–37%, and are widely distributed in soil and fresh and seawater habitats. In particular, Flavobacteriia are prominent members of marine biofilms. The type species ''Flavobacterium aquatile'' was isolated from a well in Kent, England. Flavobacteriia are a group of commensal bacteria and opportunistic pathogens. ''Flavobacterium psychrophilum'' causes the septicemic diseases rainbow trout fry syndrome and bacterial cold water disease Bacterial cold water disease (BCWD) is a bacterial disease of freshwater fish, specifically salmonid fish.

Flavobacteriales
The order Flavobacteriales comprises several families of environmental bacteria. Comparative genomics and molecular signatures ''Flavobacteriales'' is of one of the orders from the phylum ''Bacteroidota''. Comparative genomic studies have identified several conserved indels, as well as 27 proteins that are uniquely shared by different sequenced Flavobacteriales and Bacteroidota species supporting this inference. Additionally, these studies have also identified 38 proteins that seem to be specific for the species from the order ''Flavobacteriales''. Of these proteins, 26 were present in all sequenced species, while the remaining 12 were missing in only one or two species. These signature proteins provide potential molecular markers for this order. Several proteins have also been identified which are unique to the ''Flavobacteriales'' and '' Bacteroidales'' orders, indicating the species from these two orders shared a common ancestor exclusive of other ''Bacteroidota''.

Flavobacteriaceae
The family Flavobacteriaceae is composed of environmental bacteria. Most species are aerobic, while some are microaerobic to anaerobic; for example '' Capnocytophaga'' and ''Coenonia''. Genera The family ''Flavobacteriaceae'' comprises the following genera: * '' Actibacter'' Kim ''et al''. 2008 * ''Aequorivita'' Bowman and Nichols 2002 * ''Aestuariibaculum'' Jeong ''et al''. 2013 * '' Aestuariimonas'' Park ''et al''. 2018 * '' Aestuariivivens'' Park ''et al''. 2015 * ''Algibacter'' Nedashkovskaya ''et al''. 2004 * '' Algitalea'' Yoon ''et al''. 2015 * "''Algorimicrobium''" García-López ''et al''. 2019 * "''Altibacter''" Chen ''et al''. 2014 * "''Altuibacter''" Chen ''et al''. 2013 * ''Amniculibacterium'' Chen ''et al''. 2020 * "''Candidatus'' Amoebinatus" Greub ''et al''. 2004 * '' Antarcticibacterium'' Li ''et al''. 2018 * '' Antarcticimonas'' Yang ''et al''. 2014 * ''Aquaticitalea'' Xamxidin ''et al''. 2016 * ''Aquibacter'' Hameed ''et al''. 2014 * ''Aquimarina'' Nedashk ...

Polaribacter
''Polaribacter'' is a genus in the family ''Flavobacteriaceae''. They are gram-negative, Heterotrophic, aerobic bacteria that can be heterotrophic, psychrophilic or mesophilic. Most species are non-motile and species range from ovoid to rod-shaped. ''Polaribacter'' forms yellow- to orange-pigmented colonies. They have been mostly adapted to cool marine ecosystems, and their optimal growth range is at a temperature between 10 and 32 °C and at a pH of 7.0 to 8.0. They are oxidase and Catalase, catalase-positive and are able to grow using carbohydrates, amino acids, and organic acids. There is evidence of two life strategies for members of the genus, ''Polaribacter''. Some ''Polaribacter'' species are free-living and consume amino acids and carbohydrates, as well as have proteorhodopsin that enhances living in oligotrophic seawaters. Other species of ''Polaribacter'' attach to substrates in search of protein polymers. In the context of climate change, algal blooms are becoming ...

Marine Bacteria
Marine prokaryotes are marine bacteria and marine archaea. They are defined by their habitat as prokaryotes that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. All cellular life forms can be divided into prokaryotes and eukaryotes. Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, whereas prokaryotes are the organisms that do not have a nucleus enclosed within a membrane. The three-domain system of classifying life adds another division: the prokaryotes are divided into two domains of life, the microscopic bacteria and the microscopic archaea, while everything else, the eukaryotes, become the third domain. Prokaryotes play important roles in ecosystems as decomposers recycling nutrients. Some prokaryotes are pathogenic, causing disease and even death in plants and animals.

Arctic
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada ( Yukon, Northwest Territories, Nunavut), Danish Realm ( Greenland), Finland, Iceland, Norway, Russia ( Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States ( Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic.

Antarctic
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, th ...
