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 ...

Pseudomonadota
Pseudomonadota (synonym "Proteobacteria") is a major phylum of gram-negative bacteria. Currently, they are considered the predominant phylum within the domain of bacteria. They are naturally found as pathogenic and free-living (non- parasitic) genera. The phylum comprises six classes ''Acidithiobacillia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia'', and '' Zetaproteobacteria.'' The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence. Classification American microbiologist Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". The group was later formally named the 'Proteobacteria' after the Greek god Proteus, who was known to assume many forms. In 2021 the International Committee on Systematics of Prokaryotes designated the synonym Pseudomonadota, and renamed many other prokaryotic phyla as well. Th ...

Betaproteobacteria
''Betaproteobacteria'' are a class of Gram-negative bacteria, and one of the six classes of the phylum '' Pseudomonadota'' (synonym Proteobacteria). Metabolism The ''Betaproteobacteria'' comprise over 75 genera and 400 species. Together, they represent a broad variety of metabolic strategies and occupy diverse environments, ranging from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. Whilst most members of the ''Betaproteobacteria'' are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. Other genera are autotrophic, deriving their carbon from bicarbonate or carbon dioxide and their electrons from reduced inorganic ions such as nitrite, ammonium, thiosulfate or sulfide — many of these chemolithoautotrophic. ''Betaproteobacteria'' are economically important, with roles in maintaining soil pH and in elementa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neisseriales
The Neisseriaceae are a family of '' Pseudomonadota'', within the '' Neisseriales'' order of ''Betaproteobacteria''. While many organisms in the family are mammalian commensals or part of the normal flora, the genus '' Neisseria'' includes two important human pathogens, specifically those responsible for gonorrhea (caused by'' N. gonorrhoeae'') and many cases of meningitis ("meningococcal meningitis", caused by'' N. meningitidis''). As a group, the ''Neisseriaceae'' are strictly aerobic and Gram-negative, occur mainly in pairs ( diplococci), and typically do not have flagella A flagellum (; : flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores ( zoospores), and from a wide range of microorganisms to provide motility.

Walter Migula
Emil Friedrich August Walter (or Walther) Migula (born 1863 in Zyrowa, Prussia (present-day Poland); died 1938 in Eisenach, Germany) was a German botanist. In 1890, he was habilitated for botany at Karlsruhe Institute of Technology, where he spent several years as a professor. At Karlsruhe, he also worked in the bacteriology department of the Food Research Institute. He was Professor of Botany at the research academy at Eisenach. He published many articles on the subjects of cryptogamic botany, bacteriology, and plant physiology. Between 1892 and 1933 Migula issued exsiccata series, among them ''Kryptogamae Germaniae, Austriae et Helvetiae exsiccatae''.Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. – Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – München, Germany.

Aerobic Organism
An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. The ability to exhibit aerobic respiration may yield benefits to the aerobic organism, as aerobic respiration yields more energy than anaerobic respiration. Energy production of the cell involves the synthesis of ATP by an enzyme called ATP synthase. In aerobic respiration, ATP synthase is coupled with an electron transport chain in which oxygen acts as a terminal electron acceptor. In July 2020, marine biologists reported that aerobic microorganisms (mainly), in " quasi-suspended animation", were found in organically poor sediments, up to 101.5 million years old, 250 feet below the seafloor in the South Pacific Gyre (SPG) ("the deadest spot in the ocean"), and could be the longest-living life forms ever found. Types * Obligate aerobes need oxygen to grow. In a process known as cellular respiration, these organisms use oxygen to oxidize substrates (for example sugars and ...

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.

Indigoidine
Indigoidine is an organic compound of the azaquinone group. It is a blue pigment produced by some bacterial species that excrete it into the surrounding medium. History Otto Voges researched and described the bacterial species ''Bacillus indigoferus'' in 1893, renamed after him to ''Vogesella indigofera'', in Kiel, which continuously discolored the surrounding medium (water) from slightly bluish (24 hours) to royal blue (48 hours). In 1964 and 1965, Nobel laureate Richard Kuhn and his colleagues published several articles in the scientific press on the occurrence, structure and synthesis of indigoidine. In 1979, Carl-Gerd Dieris and H.-D. Scharf described another synthesis of the compound. Occurrence Indigoidine occurs in the following species of bacteria: * ''Arthrobacter atrocyaneus'' * ''Arthrobacter crystallopoietes'' * ''Arthrobacter polychromogones'' * ''Corynebacterium insidiosum'' * ''Erwinia chrysanthemi'' renamed to ''Dickea dadantii'' * ''Vogesella indigofera'' pr ...
