Bacteria
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, 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 the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, 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, suc ...

Bacteroidota
The phylum (biology), phylum Bacteroidota (synonym Bacteroidetes) is composed of three large classes of Gram-negative bacteria, 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, opportunistic pathogens, many ''Bacteroidota'' are Symbiotic bacteria, 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 Human milk oligosaccharide, oligosaccharides in mother milk support the growth of both ''Bacteroides'' and ''Bifidoba ...

Flavobacteriia
The class Flavobacteriia is composed of a single class of environmental bacteria. It contains the family Flavobacteriaceae, which is the largest family in the phylum Bacteroidota. This class is widely distributed in soil, fresh, and seawater habitats. The name is often spelt Flavobacteria, but was officially named Flavobacteriia in 2012. Flavobacteriia are gram-negative aerobic rods, 2–5 μm long, 0.1–0.5 μm wide, with rounded or tapered ends. They form circular cream to orange coloured colonies on agar, and are typically simple to successfully culture. Flavobacteriia is a chemoorganotroph and are known for their ability to mineralize or degrade dissolved organic matter of high molecular weight and particulate plant material. Flavobacteriia have impacts on both the environment and human society, as they are able to cause diseases in many organisms. They are important in the decomposition of organic matter and pollutants, and are key members in the formation of marin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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
Flavobacteriaceae is a family of rod-shaped gram negative bacteria. The family contains many environmental bacteria, with some species being potential pathogens. History The family of ''Flavobacteriaceae'' was first proposed by Reichenbach in 1989, it was approved by the IJSEM in 1992. The description of the family was emended several times in 1996 and 2002. In 2020, the family was split, with several genera moved to the newly established family of '' Weeksellaceae''. Biology Species of the ''Flavobacteriaceae'' are predominantly rod-shaped and stain gram-negative. Many species in the ''Flavobacteriaceae'' are motile, with most non-motile species formerly placed in the family now being placed in the '' Weeksellaceae''. Most species are aerobic, while some are microaerobic to anaerobic; for example '' Capnocytophaga'' and '' Coenonia''. Several members of the family are considered halophilic or psychrotolerant. The predominant respiratory quinone is menaquinone-6. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

Rod-shaped
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped (bacillus). But, there are also other morphologies such as helically twisted cylinders (example '' Spirochetes''), cylinders curved in one plane (selenomonads) and unusual morphologies (the square, flat box-shaped cells of the Archaean genus '' Haloquadratum)''. Other arrangements include pairs, tetrads, clusters, chains and palisades. Types Coccus A coccus (plural ''cocci'', from the Latin ''coccinus'' (scarlet) and derived from the Greek ''kokkos'' (berry)), is any microorganism (usually bacteria) whose overall shape is spherical or nearly spherical. Coccus refers to the shape of the bacteria and can contain multiple genera, such as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltern
A saltern is an area or installation for making salt. Salterns include modern salt-making works (saltworks), as well as hypersaline waters that usually contain high concentrations of Halophile, halophilic microorganisms, primarily haloarchaea but also other halophiles including algae and bacteria. Salterns usually begin with seawater as the initial source of brine but may also use natural saltwater springs and streams. The water is evaporated, usually over a series of ponds, to the point where sodium chloride and other salts precipitate out of the saturated brine, allowing pure salts to be harvested. Where complete evaporation in this fashion was not routinely achievable due to weather, salt was produced from the concentrated brine by boiling the brine. Background Earliest examples of pans used in the solution mining of salt date back to prehistoric times and the pans were made of ceramics known as briquetage. Later examples were made from lead and then iron. The change from lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Sea
The Yellow Sea, also known as the North Sea, is a marginal sea of the Western Pacific Ocean located between mainland China and the Korean Peninsula, and can be considered the northwestern part of the East China Sea. Names It is one of four seas named after color terms (the others being the Black Sea, the Red Sea and the White Sea), and its name is descriptive of the golden-yellow color of the silt-ridden water discharged from major rivers. The innermost bay of northwestern Yellow Sea is called the Bohai Sea (previously Gulf of Zhili / Beizhili), into which flow some of the most important rivers of northern China, such as the Yellow River (through Shandong province and its capital Jinan), the Hai River (through Beijing and Tianjin) and the Liao River (through Liaoning province). The northeastern extension of the Yellow Sea is called the Korea Bay, into which flow the Yalu River, the Chongchon River and the Taedong River. Geography Extent The International Hydrographi ...
