Denitrobacterium
''Denitrobacterium'' is a genus of Actinomycetota with a single species, in the family Coriobacteriaceae. Originally isolated from the bovine rumen, ''Denitrobacterium'' are non-motile and non-spore forming. The only described species in this genus is ''Denitrobacterium detoxificans''. The specific niche of this bacterium in the bovine rumen is theorized to be the detoxification/metabolism of nitrotoxins and miserotoxin. Characteristics of ''Denitrobacterium detoxificans'' The sole species currently described in the genus ''Denitrobacterium'', ''D. detoxificans'', is a Gram-positive, obligate anaerobe. In the study conducted by Anderson ''et al''., all of the four strains (NPOH1, NPOH2, NPOH3, and MAJ1) are shown to possess high G+C content in their DNAs (60, 58, 56, and 60 mol%, respectively) and are closely related to one another (more than 99% sequence identity). Additionally, the closest intergeneric relative is '' Coriobacterium glomerans'' with 86% sequence identit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiptage
''Hiptage'' is a genus in the Malpighiaceae, a family of about 75 genera of flowering plants in the order Malpighiales. ''Hiptage'' comprises 30 (or more) species of vines and woody shrubs growing in forests of tropical southeastern Asia from Pakistan and India to Taiwan, the Philippines, and Indonesia. The genus is distinctive in its three-winged samaras; most species bear an elongated commissural gland on the calyx. The most widely known species is ''Hiptage benghalensis'', thought to be native from India and Sri Lanka to the Philippines; it is widely cultivated for its showy fragrant flowers, and its true native range is difficult to assess. This species often escapes from cultivation; it spreads aggressively and can become a pernicious weed A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitroethane
Nitroethane is an organic compound having the chemical formula C2H5NO2. Similar in many regards to nitromethane, nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor. Preparation Nitroethane is produced industrially by treating propane with nitric acid at 350–450 °C. This exothermic reaction produces four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The reaction involves free radicals, such as CH3CH2CH2O., which arise via homolysis of the corresponding nitrite ester. These alkoxy radicals are susceptible to C—C fragmentation reactions, which explains the formation of a mixture of products.Sheldon B. Markofsky “Nitro Compounds, Aliphatic” in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH, Weinheim, 2002. . Alternatively, nitroethane can be produced by the Victor Meyer reaction of haloethanes such as chloroethane, bromo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astragalus
''Astragalus'' is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ( ''A. gummifer'', ''A. tragacantha''). Some pale-flowered vetches (''Vicia'' spp.) are similar in appearance, but they are more vine-like than ''Astragalus''. Description Most species in the genus have pinnately compound leaves. There are annual and perennial species. The flowers are formed in clusters in a raceme, each flower typical of the legume family, with three types of petals: banner, wings, and keel. The calyx is tubular or bell-shaped. Ecology ''Astragalus'' species are used as food plants by the larvae of some Lepidoptera species including many case-bearing moths of the genus ''Col ...

Resazurin
Resazurin (7-Hydroxy-3''H''-phenoxazin-3-one 10-oxide) is a phenoxazine dye that is weakly fluorescent, nontoxic, cell-permeable, and redox‐sensitive. Resazurin has a blue to purple color (at pH > 6.5) and is used in microbiological, cellular, and enzymatic assays because it can be irreversibly reduced to the pink-colored and highly fluorescent resorufin (7-Hydroxy-3''H''-phenoxazin-3-one). At circum-neutral pH, resorufin can be detected by visual observation of its pink color or by fluorimetry, with an excitation maximum at 530-570 nm and an emission maximum at 580-590 nm. When a solution containing resorufin is submitted to reducing conditions (Eh < -110 mV), almost all resorufin is reversibly reduced to the translucid non-fluorescent dihydroresorufin ...
