Nitrogen Cycle: The circulation of nitrogen in nature, consisting of a cycle of biochemical reactions in which atmospheric nitrogen is compounded, dissolved in rain, and deposited in the soil, where it is assimilated and metabolized by bacteria and plants, eventually returning to the atmosphere by bacterial decomposition of organic matter.Nitrogen Fixation: The process in certain BACTERIA; FUNGI; and CYANOBACTERIA converting free atmospheric NITROGEN to biologically usable forms of nitrogen, such as AMMONIA; NITRATES; and amino compounds.Nitrogen Compounds: Inorganic compounds that contain nitrogen as an integral part of the molecule.Nitrification: A process facilitated by specialized bacteria involving the oxidation of ammonium to nitrite and nitrate.Denitrification: Nitrate reduction process generally mediated by anaerobic bacteria by which nitrogen available to plants is converted to a gaseous form and lost from the soil or water column. It is a part of the nitrogen cycle.Nitrogen: An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.Cell Cycle: The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.Planctomycetales: A order of gram-negative bacteria whose members are found in a variety of aquatic habitats as well as animal hosts.Quaternary Ammonium Compounds: Derivatives of ammonium compounds, NH4+ Y-, in which all four of the hydrogens bonded to nitrogen have been replaced with hydrocarbyl groups. These are distinguished from IMINES which are RN=CR2.Nitrogen Isotopes: Stable nitrogen atoms that have the same atomic number as the element nitrogen, but differ in atomic weight. N-15 is a stable nitrogen isotope.Crenarchaeota: A kingdom in the domain ARCHAEA comprised of thermoacidophilic, sulfur-dependent organisms. The two orders are SULFOLOBALES and THERMOPROTEALES.Archaea: One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.Ammonia: A colorless alkaline gas. It is formed in the body during decomposition of organic materials during a large number of metabolically important reactions. Note that the aqueous form of ammonia is referred to as AMMONIUM HYDROXIDE.Nitrite Reductases: A group of enzymes that oxidize diverse nitrogenous substances to yield nitrite. (Enzyme Nomenclature, 1992) EC 1.Nitrates: Inorganic or organic salts and esters of nitric acid. These compounds contain the NO3- radical.Nitrites: Salts of nitrous acid or compounds containing the group NO2-. The inorganic nitrites of the type MNO2 (where M=metal) are all insoluble, except the alkali nitrites. The organic nitrites may be isomeric, but not identical with the corresponding nitro compounds.

Seas may be partially or entirely enclosed by land, and are smaller than the five oceans (Atlantic, Pacific, Indian, Arctic, and Antarctic).Bacteria: One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.Nitrous Oxide: Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.Ecosystem: A functional system which includes the organisms of a natural community together with their environment. (McGraw Hill Dictionary of Scientific and Technical Terms, 4th ed)DNA, Archaeal: Deoxyribonucleic acid that makes up the genetic material of archaea.Soil Microbiology: The presence of bacteria, viruses, and fungi in the soil. This term is not restricted to pathogenic organisms.Geologic Sediments: A mass of organic or inorganic solid fragmented material, or the solid fragment itself, that comes from the weathering of rock and is carried by, suspended in, or dropped by air, water, or ice. It refers also to a mass that is accumulated by any other natural agent and that forms in layers on the earth's surface, such as sand, gravel, silt, mud, fill, or loess. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1689)Soil: The unconsolidated mineral or organic matter on the surface of the earth that serves as a natural medium for the growth of land plants.Climate Change: Any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). It may result from natural factors such as changes in the sun's intensity, natural processes within the climate system such as changes in ocean circulation, or human activities.Oxidation-Reduction: A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Agriculture: The science, art or practice of cultivating soil, producing crops, and raising livestock.Blood Urea Nitrogen: The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)Nitrogen Dioxide: Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death.

The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.Biodiversity: The variety of all native living organisms and their various forms and interrelationships.Reactive Nitrogen Species: Nitrogenous products of NITRIC OXIDE synthases, ranging from NITRIC OXIDE to NITRATES. These reactive nitrogen intermediates also include the inorganic PEROXYNITROUS ACID and the organic S-NITROSOTHIOLS.Oxidoreductases: The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Cell Cycle Proteins: Proteins that control the CELL DIVISION CYCLE.

*  Steps Involved in Nitrogen Cycle
... Category: Environmental-Biotechnology. Nitrogen cycle is the conversion of atmospheric nitrogen into usable form and then its conversion back into atmospheric nitrogen. Nitrogen Cycle:- The absorption of nitrogen by plants from the soil, then consumption of plants by animals and when the animals and bacteria decompose them, returning back of nitrogen to the soil, the whole cycle is called as nitrogen cycle. Both biological and non biological methods are involved in this cycle. Nitrogen present in the air is not in the usable form. Steps involved in Nitrogen Cycle:- To convert the atmospheric nitrogen into usable nitrogen, five steps are involved. Therefore, the microbes involved in nitrogen cycle live at places where there is no oxygen like root nodules. 2 Nitrification:- It is a process of conversion of ammonia into nitrites and then nitrates. When the bacteria convert nitrogen into usable form, they gain energy from this process and need oxygen so that the process can be carried out. 3 Assimilation:- I...

*  .. Increase in ocean acidity affects the marine nitrogen cycle
« Murphy’s Laws for theoretical physicists. Welcome to a new world created by Wikileaks. Increase in ocean acidity affects the marine nitrogen cycle. News: Degrading Oceans. More carbon dioxide in the atmosphere CO2 means more carbon dioxide dissolves in the oceans. As that happens the acidity of the oceans increases technically, the pH decreases. This process is chemically obvious and the data indicates that ocean acidification is occurring and increasing. The impact on life in the seas is complex. Carbonate is destroyed by increasing acidity. Increasing ocean acidity appears to also affect the nitrogen cycle. Michael Beman of the University of California Merced, indicates that a particular phase of the nitrogen cycle called nitrification is negatively affected by ocean acidification. In water, the process of nitrification is slowed as the acidity of the water increases. To quantify the effect, Beman and his associates collected six water samples from four ocean locations in the Pacific and Atlantic. In pa...

*  The Nitrogen Cycle: Understanding the Nitrogen Cycle: Part 3
Nitrogen Cycle Part 3 : Established Aquariums Drs. The nitrogen cycle in established aquariums An established aquarium is one that the biological filtration has been matured. There are situations, however, that affect the nitrogen cycle in established aquariums, such as: adding livestock; unnoticed death in the aquarium; overfeeding; medicating the aquarium; and system maintenance. Adding aquatic life In the biological filter of an established aquarium, there are just enough bacteria to handle the biological load that is placed on the system at that time. When we add aquatic life to this system, we are increasing the amount of ammonia for the bacteria in the biological filter to metabolize. How high the toxins will become in the system is going to depend both on the amount of aquatic life added to the aquarium at one time, and the size of the aquarium. These situations include: Buying aquatic life through the mail: Because of the price of shipping, most aquarists will place large orders when purchasing their ...

Most anthropogenic metabolism happens in developed countries. According to Rosales, "Economic growth is at present the main cause of increased climate change, and climate change is a main mechanism of biodiversity loss; because of this, economic growth is a major catalyst of biodiversity loss."

University of Missouri Extension WQ261, Reviewed October 1993 Nitrogen in the Environment: Nitrogen Fixation Scott C. Killpack and Daryl Buchholz Department of Agronomy Nitrogen can be found in many forms in our environment. Nitrogen is also very important for plants to live. The earth's atmosphere is made up of 78 percent nitrogen in the form of a colorless, odorless, nontoxic gas. The same nitrogen gas found in the atmosphere can be found in spaces between soil particles. However, plants are unable to use this form of nitrogen. Certain microorganisms found in the soil are able to convert atmospheric nitrogen into forms plants can use. This is called biological nitrogen fixation. Types of nitrogen fixation In addition to biological fixation that takes place by microorganisms in the soil, fixation can also take place chemically. An example of this is in the fertilizer industry where atmospheric nitrogen N 2 can be combined with hydrogen H + to make anhydrous ammonia NH 3 and other nitrogen fertilizer prod...

*  Nitrogen fixation
... Industrial nitrogen fixation Haber process. Ambient nitrogen reduction. 4 Biological nitrogen fixation 'BNF' occurs when atmospheric nitrogen is converted to ammonia by an enzyme called a nitrogenase. Plants that contribute to nitrogen fixation include the legume family. They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. Although by far the majority of plants able to form nitrogen-fixing root nodules are in the legume family Fabaceae, there are a few exceptions:. Industrial nitrogen fixation. The Ostwald process for the production of nitric acid was discovered in 1902. Frank-Caro process and Ostwald process dominated the industrial fixation of nitrogen until the discovery of the Haber process in 1909.

We observed a decrease in DIP concentration from the edges to the centre of the gyre. Nevertheless the DIP concentrations remained above 100 nmol L 1 and T DIP was more than 6 months in the centre of the gyre; DIP availability remained largely above the level required for phosphate limitation to occur and the abs...

Researchers working at the Smithsonian Tropical Research Institute in Panama think the discovery that trees "turn up" their ability to capture or "fix" nitrogen from the air and release it into the soil as the forest makes a comeback has far-reaching implications for forest restoration projects to mitigate global warming. "This is the first solid case showing how nitrogen fixation by tropical trees directly affects the rate of carbon recovery after agricultural fields are abandoned," said Jefferson Hall, STRI staff scientist.

An international team of scientists from the University of Frankfurt in Germany, Berkeley Lab, Kansas State University, and Auburn University has now resolved the issue with an appropriate twist of quantum fuzziness. By means of coincident detection of the photoelectron ejected from molecular nitrogen and the Auger electron emitted femtoseconds later, the team found that how the measurements are done determines which description—localized or delocalized—is valid. Artist’s view of the asymmetric angular distributions obtained by coincident detection of the photoelectron emerging from a N 2 molecule blue of the photoelectron left and the Auger electron emitted 7 fs later right for the case of a localized core hole in a N 2 molecule. As the two electrons form an entangled state, the Auger electron right is also localized.

... 'The Fixer Uppers' is a 1935 short film starring Laurel and Hardy, directed by Charles Rogers and produced by Hal Roach. Plot Cast Notes References External links. Plot. Christmas card salesman Stan and Ollie are persuaded to help a woman Mae Busch spice up her loveless marriage by making her husband jealous. The spouse involved, a temperamental artist played by Charles Middleton, is however made rather too jealous for comfort, and puts Ollie in peril when he challenges him to a duel to the death at midnight and pledges to track him "to the end of the world" if he does not show up. Stan and Ollie discuss the challenge in a nearby bar and it occurs to them that the husband cannot know where they live, so Ollie complacently telephones him to inform him he will not be there and they both insult him. They then get drunk with a neighbor of the couple played by Arthur Housman. They are discovered when Stan starts snoring and pistols are produced but the wife tells Ollie she has replaced the bullets with blanks...

Human impact on the nitrogen cycleDiazotroph: Diazotrophs are bacteria and archaea that fix atmospheric nitrogen gas into a more usable form such as ammonia.Nitrogen trichlorideWarner OlandAerobic denitrification: Aerobic denitrification or co-respiration the simultaneous use of both oxygen (O2) and nitrate (NO3−) as oxidizing agents, performed by various genera of microorganisms. This process differs from anaerobic denitrification not only in its insensitivity to the presence of oxygen, but also in that it has a higher potential to create the harmful byproduct nitrous oxide.Nitrogen deficiencyStart point (yeast): The Start checkpoint is a major cell cycle checkpoint in yeast. The Start checkpoint ensures irreversible cell-cycle entry even if conditions later become unfavorable.Scalindua wagneri: Candidatus Scalindua wagneri is a Gram-negative coccoid-shaped bacterium that was first isolated from a wastewater treatment plant. This bacterium is an obligate anaerobic chemolithotroph that undergoes anaerobic ammonium oxidation (anammox).Tetramethylammonium chlorideIsotopic signature: An isotopic signature (also isotopic fingerprint) is a ratio of non-radiogenic 'stable isotopes', stable radiogenic isotopes, or unstable radioactive isotopes of particular elements in an investigated material. The ratios of isotopes in a sample material are measured by isotope ratio mass spectrometry.Domain (biology): In biological taxonomy, a domain (also superregnum, superkingdom, empire, or regio) is the highest taxonomic rank of organisms in the three-domain system of taxonomy designed by Carl Woese, an American microbiologist and biophysicist. According to the Woese system, introduced in 1990, the tree of life consists of three domains: Archaea (a term which Woese created), Bacteria, and Eukaryota.Ammonia transporterPeroxynitrous acidHyponitriteDeep chlorophyll maximum: A deep chlorophyll maximum (DCM) is a subsurface maximum in the concentration of chlorophyll in the ocean or a lake. A DCM is not always present--sometimes there is more chlorophyll at the surface than at any greater depth--but it is a common feature of most aquatic ecosystems.Anoxic event: Oceanic anoxic events or anoxic events (anoxia conditions) refer to intervals in the Earth's past where portions of oceans become depleted in oxygen (O2) at depths over a large geographic area. During some of these events, euxinia develops - euxinia refers to anoxic waters that contain hydrogen sulfide.Exogenous bacteria: Exogenous bacteria are microorganisms introduced to closed biological systems from the external world. They exist in aquatic and terrestrial environments, as well as the atmosphere.Nitrous oxide and oxygen: A mix of nitrous oxide 50% and oxygen 50% is a medical analgesic gas, commonly known as Entonox (a registered trademark of BOC) or Nitronox, or colloquially as "gas and air", and is frequently used in pre-hospital care, childbirth and emergency medicine situations by medical professionals such as doctors, nurses, midwives and paramedics.EcosystemGemmatimonadetes: The Gemmatimonadetes are a family of bacteria, given their own phylum (Gemmatimonadetes). This bacterium makes up about 2% of soil bacterial communities and has been identified as one of the top nine phyla found in soils; yet, there are currently only six cultured isolates.Nankai Trough gas hydrate site: Nankai Methane Hydrate Site (or Japanese Methane Hydrate R&D Program at Nankai, Nankai Trough Methane Hydrate Site) is located in the Nankai Trough, Japan.Index of soil-related articles: This is an index of articles relating to soil.Climate change in the United Kingdom: Climate change in the United Kingdom has been a subject of protests and controversies, and various policies have been developed to mitigate its effects. It is estimated to demand at least 80-85% emission reductions in the EU during 2008-2050 with reductions as soon as technically possible.Table of standard reduction potentials for half-reactions important in biochemistry: The values below are standard reduction potentials for half-reactions measured at 25°C, 1 atmosphere and a pH of 7 in aqueous solution.Branching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Chilalo Agricultural Development Union: Chilalo Agricultural Development Union (CADU) is the first comprehensive package project established in Arsi Zone, Oromia Region, Ethiopia to modernize traditional subsistence agriculture. The major components of the package programmes include fertilizers, ameliorated seeds, farm credits, marketing facilities, better tools and implements, and improved storage facilities.Renal functionPeat swamp forest: Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat.Alliance for Zero Extinction: Formed in 2000 and launched globally in 2005, the Alliance for Zero Extinction (AZE) comprises 100 non-governmental biodiversity conservation organizations working to prevent species extinctions by identifying and safeguarding sites where species evaluated to be Endangered or Critically Endangered under International Union for Conservation of Nature (IUCN) criteria only exist at one location on earth."Zero Extinction - Home.NitrotyrosineGlucose-methanol-choline oxidoreductase family: In molecular biology, the glucose-methanol-choline oxidoreductase family (GMC oxidoreductase) is a family of enzymes with oxidoreductase activity.Coles PhillipsNitrogen oxide sensor: A nitrogen oxide sensor or NOx sensor is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile or truck tailpipe or a smokestack.Global microbial identifier: The genomic epidemiological database for global identification of microorganisms or global microbial identifier (GMI) is a platform for storing whole genome sequencing (WGS) data of microorganisms, for the identification of relevant genes and for the comparison of genomes to detect and track-and-trace infectious disease outbreaks and emerging pathogens. The database holds two types of information: 1) genomic information of microorganisms, linked to, 2) metadata of those microorganism such as epidemiological details.Pii nitrogen regulatory proteinsDNA sequencer: A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).Carbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.Estrous cycle: The estrous cycle (also oestrous cycle; derived from Latin oestrus and originally from Greek οἶστρος meaning sexual desire) comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases or pregnancies.Organic fertilizer: Organic fertilizers are fertilizers derived from animal matter, human excreta or vegetable matter. (e.Reverse Krebs cycle: The reverse Krebs cycle (also known as the reverse tricarboxylic acid cycle, the reverse TCA cycle, or the reverse citric acid cycle)Glutamine synthetase

(4/78) Indications of recovery from hypoxia in the inner Stockholm archipelago.

Improved benthic conditions compared to the 1990s were found during benthic investigations, including sediment and benthic macrofauna in the inner Stockholm archipelago during 2008. In the 1990s, these areas were dominated by black and laminated surface sediments and very sparse fauna. A clear relationship was found when comparing sediment status with the benthic macrofauna. Reduced surface sediment and impoverished macroinvertebrate community was only found at one sampling station representing an enclosed part of the inner archipelago, whereas the other seven stations, with depths ranging from 20 to 50 m, had oxidized surface sediments and considerable biomasses of benthic macrofauna (6-65 g m(-2)) dominated by the invading polychaete Marenzelleria neglecta. An extrapolation of the results shows that, within the investigated area, the coverage of reduced surface sediments had decreased from approximately 17% in the late 1990s to 4% in 2008.  (+info)
