Gram-positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain (saf ...

Paenarthrobacter
''Paenarthrobacter'' is a genus of bacteria from the family Micrococcaceae. ''Paenarthrobacter'' members share the following properties: * A3a type peptidoglycan * Menaquinone MK-9(H2) * A polar lipid profile composed primarily of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, dimannosylglyceride, and monogalactosyldiacylglycerol; and to a lesser extent, trimannosyldiacylglycerol. * A fatty acid composition primarily from anteiso-C15:0, and to a lesser extent iso-C15:0, iso-C16:0, anteiso-C17:0 and isoC14. * A genomic GC content In molecular biology and genetics, GC-content (or guanine-cytosine content) is the percentage of nitrogenous bases in a DNA or RNA molecule that are either guanine (G) or cytosine (C). This measure indicates the proportion of G and C bases out o ... in the range of 61.3–62.5 mol%. References External links * {{Taxonbar, from=Q27438445 Micrococcaceae ...

Deutsche Sammlung Von Mikroorganismen Und Zellkulturen
The Leibniz Institute DSMZ - German Collection of Microorganisms and Cell Cultures GmbH (German: ''Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH''), located in Braunschweig, is a research infrastructure in the Leibniz Association. Also the DSMZ is the world's most diverse collection of bioresources (status 2021: 75,000 bioresources). These include microorganisms (including more than 32,000 bacterial strains, 690 archaeal strains, 7,000 strains of yeasts and fungi) as well as more than 840 human and animal cell cultures, over 1. 500 plant viruses, over 940 bacteriophages, and 250 plasmids (status 2021). Since 2010, the scientific director of the Leibniz Institute DSMZ has been Jörg Overmann, a microbiologist with a PhD. He holds a professorship in microbiology at the Technical University of Braunschweig. Since August 2018, he has led the institute in a dual leadership with Bettina Fischer as administrative director.

Atrazine
Atrazine is a chlorinated herbicide of the triazine class. It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), soybean and sugarcane and on turf, such as golf courses and residential lawns. Atrazine's primary manufacturer is Syngenta and it is one of the most widely used herbicides in the United States, Canadian, and Australian agriculture. Its use was banned in the European Union in 2004, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could not show that this could be prevented nor that these levels were safe.European Commission.2004/248/EC: Commission Decision of 10 March 2004 concerning the non-inclusion of atrazine in Annex I to Council Directive 91/414/EEC and the withdrawal of authorisations for plant protection products containing this active substance (Text with EEA relevance) (notified under document number C(2004) 731)Decision 2004/248/EC - Official Journal L 078, Decision 2004/248/EC.

Nicotine
Nicotine is a naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and ''Duboisia hopwoodii'') and is widely used recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Nicotine is also present at ppb-concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an antiherbivore toxin; consequently, nicotine was widely used as an insecticide in the past, and neonicotinoids (structurally similar to nicotine), such as imidacloprid, are s ...

Creatine
Creatine ( or ) is an organic compound with the nominal formula (H2N)(HN)CN(CH3)CH2CO2H. It exists in various modifications (tautomers) in solution. Creatine is found in vertebrates where it facilitates recycling of adenosine triphosphate (ATP), primarily in muscle and brain tissue. Recycling is achieved by converting adenosine diphosphate (ADP) back to ATP via donation of phosphate groups. Creatine also acts as a buffer. History Creatine was first identified in 1832 when Michel Eugène Chevreul isolated it from the basified water-extract of skeletal muscle. He later named the crystallized precipitate after the Greek word for meat, κρέας (''kreas''). In 1928, creatine was shown to exist in equilibrium with creatinine. Studies in the 1920s showed that consumption of large amounts of creatine did not result in its excretion. This result pointed to the ability of the body to store creatine, which in turn suggested its use as a dietary supplement. In 1912, Harvard Univer ...

Nicotine Dehydrogenase
In enzymology, a nicotine dehydrogenase () is an enzyme that catalyzes the chemical reaction :(S)-nicotine + acceptor + H2O \rightleftharpoons (S)-6-hydroxynicotine + reduced acceptor The 3 substrates of this enzyme are (S)-nicotine, acceptor, and H2O, whereas its two products are (S)-6-hydroxynicotine and reduced acceptor. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors. The systematic name of this enzyme class is nicotine:acceptor 6-oxidoreductase (hydroxylating). Other names in common use include nicotine oxidase, D-nicotine oxidase, nicotine:(acceptor) 6-oxidoreductase (hydroxylating), and L-nicotine oxidase. It has 2 cofactors: metal A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typicall ..., and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
