Microfungi
Microfungi or micromycetes are fungi—eukaryotic organisms such as molds, mildews and rusts—which have microscopic spore-producing structures. They exhibit tube tip-growth and have cell walls composed of chitin, a polymer of ''N''-acetylglucosamine. Microfungi are a paraphyletic group, distinguished from macrofungi only by the absence of a large, multicellular fruiting body. They are ubiquitous in all terrestrial and freshwater and marine environments, and grow in plants, soil, water, insects, cattle rumens, hair, and skin. Most of the fungal body consists of microscopic threads, called hyphae, extending through the substrate in which it grows. The mycelia of microfungi produce spores that are carried by the air, spreading the fungus. Many microfungi species are benign, existing as soil saprotrophs, for example, largely unobserved by humans. Many thousands of microfungal species occur in lichens, forming symbiotic relationships with algae. Other microfungi, such as those of ...

Mold (fungus)
A mold () or mould () is one of the structures that certain fungi can form. The dust-like, colored appearance of molds is due to the formation of spores containing fungal secondary metabolites. The spores are the dispersal units of the fungi. Not all fungi form molds. Some fungi form mushrooms; others grow as single cells and are called microfungi (for example yeasts). A large and taxonomically diverse number of fungal species form molds. The growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls (septa) may delimit connected compartments along the hyphae, each containing one or multiple, genetically identical nuclei. The dusty texture of many molds is caused by profuse production of asexual spores (conidia) form ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fusarium Venenatum
''Fusarium venenatum'' is a microfungus of the genus ''Fusarium'' that has a high protein content. One of its strains is used commercially for the production of the single cell protein mycoprotein Quorn. ''Fusarium venenatum'' was discovered growing in soil in Buckinghamshire in the United Kingdom, in 1967 by ICI as part of the effort during the 1960s to find alternative sources of food to fill the protein gap caused by the growing world population.From petri dish to plate: The £172m fungi published 2005-06-07, accessed 2011-06-27 It was originally misidentified as '' [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Penicillium
''Penicillium'' () is a genus of Ascomycota, ascomycetous fungus, fungi that is part of the mycobiome of many species and is of major importance in the natural environment, in food spoilage, and in food and drug production. Some members of the genus produce penicillin, a molecule that is used as an antibiotic, which kills or stops the growth of certain kinds of bacteria. Other species are used in cheesemaking. According to the ''Dictionary of the Fungi'' (10th edition, 2008), the widespread genus contains over 300 species. Taxonomy The genus was first described in the scientific literature by Johann Heinrich Friedrich Link in his 1809 work ; he wrote, , () where means "having tufts of fine hair". Link included three species—''Penicillium candidum, P. candidum'', ''Penicillium expansum, P. expansum'', and ''Penicillium glaucum, P. glaucum''—all of which produced a brush-like conidiophore (asexual spore-producing structure). The common apple rot fungus ''P.&n ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sauternes (wine)
Sauternes () is a French sweet wine from the region of the same name in the Graves section in Bordeaux. Sauternes wine is made from Sémillon, sauvignon blanc, and muscadelle grapes that have been affected by ''Botrytis cinerea'', also known as noble rot. This causes the grapes to become partially raisined, resulting in concentrated and distinctively flavored wines. Due to its climate, Sauternes is one of the few wine regions where infection with noble rot is a frequent occurrence. Even so, production is a hit-or-miss proposition, with widely varying harvests from vintage to vintage. Wines from Sauternes, especially the ''Premier Cru Supérieur'' estate Château d'Yquem, can be very expensive, largely due to the very high cost of production. Barsac lies within Sauternes and is entitled to use either name. Somewhat similar but less expensive and typically less-distinguished wines are produced in the neighboring regions of Monbazillac, Cérons, Loupiac and Cadillac. I ...

Noble Rot
Noble rot (; ; ; ) is the beneficial form of a grey fungus, ''Botrytis cinerea'', affecting wine grapes. Infestation by ''Botrytis'' requires warm and humid conditions, typically around 20 degrees Celsius and above 80% humidity. If the weather stays wet, the undesirable form, "bunch rot" or "grey rot", adversely affects winemaking by disrupting fermentation and changing the taste, aroma, and appearance of the final wine Grapes typically become infected with ''cinerea'' when they are ripe. If they are then exposed to drier conditions and become partially raisined, this form of infection is known as noble rot. Grapes picked at a certain point during infestation can produce particularly fine and concentrated sweet wine. Wines produced by this method are known as botrytized wines, and are considered a distinct category of dessert wines. The primary distinction between botrytized wines and other naturally sweet, non-fortified sweet wines, such as late-harvest wines, ice wines, or ...

Botrytis Cinerea
''Botrytis cinerea'' is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes, the Aszú of Tokaji, or Grasă de Cotnari. The species name ''Botrytis cinerea'' is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their conidiophores, and "ashes" just refers to the greyish colour of the spores ''en masse''. The fungus is usually referred to by its anamorph (asexual form) name, because ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

In bino ... of fungus, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia. Macroconidia are mostly borne laterally directly on the hyphae or on short pedicels, and are thin- or thick-walled, clavate to fusiform, and range from 4 to 8 by 8 to 50 μm in size. Macroconidia are few or absent in many species. Microconidia are spherical, pyriform to clavate or of irregular shape, and range from 2 to 3 by 2 to 4 μm in size.

Athlete's Foot
Athlete's foot, known medically as ''tinea pedis'', is a common skin infection of the feet caused by a fungus. Signs and symptoms often include itching, scaling, cracking and redness. In rare cases the skin may blister. Athlete's foot fungus may infect any part of the foot, but most often grows between the toes. The next most common area is the bottom of the foot. The same fungus may also affect the nails or the hands. It is a member of the group of diseases known as '' tinea''. Athlete's foot is caused by a number of different funguses, including species of '' Trichophyton'', '' Epidermophyton'', and '' Microsporum''. The condition is typically acquired by coming into contact with infected skin, or fungus in the environment. Common places where the funguses can survive are around swimming pools and in locker rooms. They may also be spread from other animals. Usually diagnosis is made based on signs and symptoms; however, it can be confirmed either by culture or seeing hy ...

Mycoprotein
Mycoprotein (lit. "protein from fungus"), also known as mycelium-based protein or fungal protein, is a form of single-cell protein derived from fungi for human consumption. Though these products derived from mycoprotein often are referred to as plant-based, this assortment is per definition wrong as the fungal kingdom, including mushroom-forming species as well as yeasts and molds, are separate from those of animals (Animalia) and plants ( Plantae). With that said, mycoprotein should neither be confused with mushroom-based products, as the part of fungi grown for mycoprotein is the vegetative growth of the fungi, called mycelium, which can be compared to the roots of the organism. Metaphorically, the mushroom and the mycelium are as similar as a fruit is to the roots of its tree. The market History The discovery of mycoprotein was a result of "The Green Protein Revolution"-inspired British scientists looking for a sustainable alternative protein that could offset ...

Alexander Fleming
Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould ''Penicillium rubens'' has been described as the "single greatest victory ever achieved over disease". For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Chain. He also discovered the enzyme lysozyme from his nasal discharge in 1922, and along with it a bacterium he named ''Micrococcus lysodeikticus'', later renamed ''Micrococcus luteus''. Fleming was Knight Bachelor, knighted for his scientific achievements in 1944. In 1999, he was named in ''Time (magazine), Time'' magazine's list of the Time 100: The Most Important People of the Century, 100 Most Important People of the 20th century. In 2002, he was chosen in th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Penicillin
Penicillins (P, PCN or PEN) are a group of beta-lactam antibiotic, β-lactam antibiotics originally obtained from ''Penicillium'' Mold (fungus), moulds, principally ''Penicillium chrysogenum, P. chrysogenum'' and ''Penicillium rubens, P. rubens''. Most penicillins in clinical use are synthesised by ''Penicillium chrysogenum, P. chrysogenum'' using industrial fermentation, deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: benzylpenicillin, penicillin G (intramuscular injection, intramuscular or Intravenous therapy, intravenous use) and phenoxymethylpenicillin, penicillin V (given by mouth). Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococcus, staphylococci and streptococcus, streptococci. They are still widely used today for various bacterial infections, though many types of bacteria have developed antibiotic res ...
