Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Hemel Hempstead
Hemel Hempstead () is a town in the Dacorum district in Hertfordshire, England, northwest of London, which is part of the Greater London Urban Area. The population at the 2011 census was 97,500. Developed after the Second World War as a new town, it has existed since the 8th century and was granted its town charter by Henry VIII in 1539. Nearby towns are Watford, St Albans and Berkhamsted. History Origin of the name The settlement was called by the name Henamsted or Hean-Hempsted in Anglo-Saxon times and in William the Conqueror's time by the name of Hemel-Amstede. The name is referred to in the Domesday Book as Hamelamestede, but in later centuries it became Hamelhamsted, and, possibly, Hemlamstede. In Old English, ''-stead'' or ''-stede'' simply meant "place" (reflected in German ''Stadt'' and Dutch ''stede'' or ''stad'', meaning "city" or "town"), such as the site of a building or pasture, as in clearing in the woods, and this suffix is used in the names of other E ...

Shewanella Oneidensis
''Shewanella oneidensis'' is a bacterium notable for its ability to reduce metal ions and live in environments with or without oxygen. This proteobacterium was first isolated from Lake Oneida, NY in 1988, hence its name. ''S. oneidensis'' is a facultative bacterium, capable of surviving and proliferating in both aerobic and anaerobic conditions. The special interest in ''S. oneidensis'' MR-1 revolves around its behavior in an anaerobic environment contaminated by heavy metals such as iron, lead and uranium. Experiments suggest it may reduce ionic mercury to elemental mercury and ionic silver to elemental silver. Cellular respiration for these bacteria is not restricted to heavy metals though; the bacteria can also target sulfates, nitrates and chromates when grown anaerobically. Name This species is referred to as ''S. oneidensis'' MR-1, indicating "manganese reducing", a special feature of this organism. It is a common misconception to think that MR-1 refers to "metal-reduc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geobacter Sulfurreducens
''Geobacter sulfurreducens'' is a gram-negative metal and sulphur-reducing proteobacterium. It is rod-shaped, obligately anaerobic, non-fermentative, has flagellum and type four pili, and is closely related to ''Geobacter metallireducens''. ''Geobacter sulfurreducens'' is an anaerobic species of bacteria that comes from the family of bacteria called Geobacteraceae. Under the genus of Geobacter, ''G. sulfurreducens'' is one out of twenty different species. The Geobacter genus was discovered by Derek R. Lovley in 1987. ''G. sulfurreducens'' was first isolated in Norman, Oklahoma, USA from materials found around the surface of a contaminated ditch. Characteristics ''Geobacter sulfurreducens'' is a rod-shaped microbe with a gram-negative cell wall. Geobacter is known as a type of bacteria that is able to conduct levels of electricity, and the species ''G. sulfurreducens'' is also known as “electricigens” due to their ability to create an electric current and produce electrici ...

Mineralogical Magazine
The Mineralogical Society of Great Britain and Ireland began in 1876. Its main purpose is to disseminate scientific knowledge of the Mineral Sciences (mineralogy) as it may be applied to the fields of crystallography, geochemistry, petrology, environmental science and economic geology. In support of this vision, the society publishes scientific journals, books and monographs. It also organizes and sponsors scientific meetings, and the society connects with other societies which have similar scientific interests. Some of these other societies are the International Mineralogical Association, the European Mineralogical Union, the Mineralogical Society of America, the Mineralogical Association of Canada, the Geological Society of London, IOM3, the North of England Institute of Mining and Mechanical Engineers and the Microbiology Society. Publications The Society publishes a variety of book series; these are entitled the "Landmark Series", the "Mineralogical Society Special Seri ...

Biotechnology
Biotechnology is the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services. The term ''biotechnology'' was first used by Károly Ereky in 1919, meaning the production of products from raw materials with the aid of living organisms. Definition The concept of biotechnology encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials ...

Microbial Metabolism
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe's ecological niche, and often allow for that microbe to be useful in industrial processes or responsible for biogeochemical cycles. Types All microbial metabolisms can be arranged according to three principles: 1. How the organism obtains carbon for synthesizing cell mass:Morris, J. et al. (2019). "Biology: How Life Works", 3rd edition, W. H. Freeman. * autotrophic – carbon is obtained from carbon dioxide () * heterotrophic – carbon is obtained from organic compounds * mixotrophic – carbon is obtained from both organic compounds and by fixing carbon dioxide 2.

Microorganism
A microorganism, or microbe,, ''mikros'', "small") and ''organism'' from the el, ὀργανισμός, ''organismós'', "organism"). It is usually written as a single word but is sometimes hyphenated (''micro-organism''), especially in older texts. The informal synonym ''microbe'' () comes from μικρός, mikrós, "small" and βίος, bíos, "life". is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Because mi ...
