Jane Gibson
Audrey Jane Gibson (née Pinsent; October 5, 1924 – June 10, 2008) was a British-American microbiologist and biochemist who worked in the field of photosynthetic bacteria. She discovered that selenium is required by the metabolism of coliform bacteria and described a new species of sulphur bacterium in the genus ''Chloroherpeton''. She became a Professor at Cornell University in 1979 and was editor of the scientific journal ''Applied and Environmental Microbiology''. Early life Born Audrey Jane Pinsent on October 5, 1924 in Paris, daughter of Gerald Hume Saverie Pinsent (1888–1976), whom later became comptroller-general of the UK National Debt Office. Her mother was Katharine Kentisbeare (1884–1949), daughter of the Liberal MP, Sir George Radford. Her early years were spent in both Switzerland and Devon. She attended The Maynard School in Exeter, England and went on to earn a first-class honours degree in biochemistry at Newnham College, Cambridge in 1946 under the adviso ...

Lister Institute Of Preventive Medicine
The Lister Institute of Preventive Medicine, informally known as the Lister Institute, was established as a research institute (the British Institute of Preventive Medicine) in 1891, with bacteriologist Marc Armand Ruffer as its first director, using a grant of £250,000 from Edward Cecil Guinness of the Guinness family. It had premises in Chelsea in London, Sudbury in Suffolk, and Elstree in Hertfordshire, England. It was the first medical research charity in the United Kingdom. It was renamed the Jenner Institute (after Edward Jenner, the pioneer of smallpox vaccine) in 1898 and then, in 1903, as the Lister Institute in honour of the great surgeon and medical pioneer, Dr Joseph Lister. In 1905, the institute became a school of the University of London. History The early history of the Lister Institute could best be described as having a chequered history. It began with French chemist and microbiologist Louis Pasteur in 1880 when two rabid dogs were brought to Pasteur fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonia
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the chemical formula, formula . A Binary compounds of hydrogen, stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell. It is widely used in fertilizers, refrigerants, explosives, cleaning agents, and is a precursor for numeous chemicals. Biologically, it is a common nitrogenous waste, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to fertilisers. Around 70% of ammonia produced industrially is used to make fertilisers in various forms and composition, such as urea and diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many chemicals. In many countries, it is classified as an List of extremely hazardous substances, extremely hazardous substance. Ammonia is toxic, cau ...

Cytochrome
Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in the electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of Biochemistry and Molecular Biology (IUBMB), cytochromes a, cytochromes b, cytochromes c and cytochrome d. Cytochrome function is linked to the reversible redox change from ferrous (Fe(II)) to the ferric (Fe(III)) oxidation state of the iron found in the heme core. In addition to the classification by the IUBMB into four cytochrome classes, several additional classifications such as cytochrome o and cytochrome P450 can be found in biochemical literature. History Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In the 1920s, Keilin rediscovered these respiratory pigments and na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Escherichia Coli
''Escherichia coli'' ( )Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus '' Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' strains are part of the normal microbiota of the gut, where they constitute about 0.1%, along with other facultative anaerobes. These bacteria are mostly harmless or even beneficial to humans. For example, some strains of ''E. coli'' benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by harmful pathogenic bacteria. These mutually beneficial relationships between ''E. coli'' and humans are a type of mutualistic biological relationship—where both the humans and the ''E. coli'' are benefitting each other. ''E. coli'' is expelled into the environment within fecal matter. The bacterium grows massi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
