Vibrio Natriegens
''Vibrio natriegens'' is a Gram-negative marine bacterium. It was first isolated from salt marsh mud. It is a salt-loving organism (halophile) requiring about 2% NaCl for growth. It reacts well to the presence of sodium ions which appear to stimulate growth in ''Vibrio'' species, to stabilise the cell membrane, and to affect sodium-dependent transport and mobility. Under optimum conditions, and all nutrients provided, the doubling time of ''V. natriegens'' can be less than 10 minutes. ''V. natriegens'' is able to successfully live and rapidly divide in its coastal areas due its large range of metabolic fuel. Recent research has displayed that ''Vibrio natriegens'' has a flexible metabolism, which allows it to consume a large variety of carbon substrates, reduce nitrates, and even fix nitrogen from the atmosphere under nitrogen-limiting and anaerobic conditions. In the laboratory, the growth medium can be easily changed, thus affecting the growth rate of a culture. ''V. natriegens' ...

Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amygdalin
Amygdalin (from Ancient Greek: ' "almond") is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels) of apricots, bitter almonds, apples, peaches, cherries, and plums. Amygdalin is classified as a cyanogenic glycoside because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase. Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning. Since the early 1950s, both amygdalin and a chemical derivative named ''laetrile'' have been promoted as alternative cancer treatments, often under the misnomer vitamin B17 (neither amygdalin nor laetrile is a vitamin). Scientific study has found them to not only be clinically ineffective in treating cancer, but also potentially toxic or lethal when taken by mouth due to cyanide poisoning. The promotion of laetrile to treat cancer has been described in the medical literature a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nature Methods
''Nature Methods'' is a monthly peer-reviewed scientific journal covering new scientific techniques. It was established in 2004 and is published by Springer Nature under the Nature Portfolio. Like other ''Nature'' journals, there is no external editorial board and editorial decisions are made by an in-house team, although peer review by external experts forms a part of the review process. Every year, the journal highlights a field, approach, or technique that has enabled recent major advances in life sciences research as the "Method of the Year".

BioRxiv
bioRxiv (pronounced "bio-archive") is an open access preprint repository for the biological sciences co-founded by John Inglis and Richard Sever in November 2013. It is hosted by the Cold Spring Harbor Laboratory (CSHL). As preprints, papers hosted on bioRxiv are not peer-reviewed, but undergo basic screening and checked against plagiarism. However, peer reviews from other sources may be posted alongside preprints. Moreover, readers may post comments. It has been measured that two thirds of the papers posted in bioRxiv are later published in peer-reviewed journals. A service called Rxivist parses the metadata of preprints from bioRxiv, and combines it with data from Twitter allowing to detect trending preprints. MedRxiv, and its sister site, bioRxiv, have been major sources for the dissemination of COVID-19 research. History BioRxiv was inspired by and intends to complement the arXiv repository, which mostly focuses on mathematics, physics and connected disciplines, launche ...

D-Turanose
Turanose is a reducing disaccharide. The -isomer is naturally occurring. Its systematic name is α--glucopyranosyl-(1→3)-α--fructofuranose. It is an analog of sucrose not metabolized by higher plants, but rather acquired through the action of sucrose transporters for intracellular carbohydrate signaling. In addition to its involvement in signal transduction, -(+)-turanose can also be used as a carbon source by many organisms including numerous species of bacteria and fungi. at Sigma-Aldrich

Glycogen
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body. Glycogen functions as one of two forms of energy reserves, glycogen being for short-term and the other form being triglyceride stores in adipose tissue (i.e., body fat) for long-term storage. In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the liver, glycogen can make up 5–6% of the organ's fresh weight, and the liver of an adult, weighing 1.5 kg, can store roughly 100–120 grams of glycogen. In skeletal muscle, glycogen is found in a low concentration (1–2% of the muscle mass) and the skeletal muscle of an adult weighing 70 kg stores roughly 400 grams of glycogen. The amount of glycogen stored in the body—particularly within the muscles and liver—mostly depends on physical training, bas ...

Trehalose
Trehalose (from Turkish '' tıgala'' – a sugar derived from insect cocoons + -ose) is a sugar consisting of two molecules of glucose. It is also known as mycose or tremalose. Some bacteria, fungi, plants and invertebrate animals synthesize it as a source of energy, and to survive freezing and lack of water. Extracting trehalose was once a difficult and costly process, but around 2000, the Hayashibara company ( Okayama, Japan) discovered an inexpensive extraction technology from starch. Trehalose has high water retention capabilities, and is used in food, cosmetics and as a drug. A procedure developed in 2017 using trehalose allows sperm storage at room temperatures. Structure Trehalose is a disaccharide formed by a bond between two α-glucose units. It is found in nature as a disaccharide and also as a monomer in some polymers. Two other isomers exist, α,β-trehalose, otherwise known as neotrehalose, and β,β-trehalose (also referred to as isotrehalose). Neotrehalose has ...

Melibiose
Melibiose is a reducing disaccharide formed by an α-1,6 linkage between galactose and glucose (D-Gal-α(1→6)-D-Glc). It differs from lactose in the chirality of the carbon where the galactose ring is closed and that the galactose is linked to a different point on the glucose moiety. It can be formed by invertase-mediated hydrolysis of raffinose, which produces melibiose and fructose. Melibiose can be broken down into its component saccharides, glucose and galactose, by the enzyme alpha-galactosidase, such as MEL1 from ''Saccharomyces pastorianus'' (lager yeast). Melibiose cannot be used by ''Saccharomyces cerevisiae ''Saccharomyces cerevisiae'' () (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungus microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been o ...''
