Uncinocarpus Queenslandicus
''Uncinocarpus queenslandicus'' is a species of microfungi that grows in soil and keratinous materials, such as hair. It was the fourth species to be designated as part of the genus ''Uncinocarpus''. Its name is derived from the Australian state of Queensland, where it was first isolated. Taxonomy Three synonyms for ''U. queenslandicus'' were first described in 1976 by A.E. Apinis and R.G. Rees as ''Apinisa queenslandicus'' during a survey of keratinous soil fungi in Queensland, Australia. Indian mycologists Banani Sur and Gouri R. Ghosh first described ''Orromyces spiralis'' in 1985 during a survey of keratinophilic soil fungi. In 1987, Spanish mycologists J. Guarro, L. Punsola and J. Cano first described ''Byssonygena reticulata'' as the type species of a new genus. Canadian mycologists Lynne Sigler, Arlene Flis and J.W. Carmichael first proposed that all three of these species be placed in the genus ''Uncinocarpus'' in 1998. Though crossings between these three species and ''U ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keratin
Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins''. Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos, and armadillos' osteoderm. The only other biological matter known to approximate the toughness of keratinized tissue is chitin. Keratin comes in two types, the primitive, softer forms found in all vertebrates and harder, derived forms found only amon ...

Uncinocarpus
''Uncinocarpus'' is a genus of fungi within the Onygenaceae family. The name is derived from the Latin word ''uncinus'', meaning "hook" and the Greek word ''karpos'' (καρπός), meaning "fruit". It was distinguished from the genus ''Gymnoascus'' based on keratinolytic capacity, ascospore morphology and the development of hooked, occasionally spiraling appendages. Alternatively, ''Uncinocarpus'' species may possess helically coiled or smooth, wavy appendages, or lack appendages altogether, an example of such species being '' U. orissi''. Being a close non-pathogenic relative of the pathogenic dimorphic fungi Coccidioides immitis and Coccidioides posadasii, which cause Coccidioidomycosis, it is used in genomic research to help develop human vaccination, which might alleviate the Valley fever A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uncinocarpus Orissi
''Uncinocarpus orissi'' is a species of microfungus that grows on dung and other keratinous materials, such as hair. It was the third species to be designated as part of the genus ''Uncinocarpus'' by Canadian mycologists Lynne Sigler, Arlene Flis and J.W. Carmichael in 1998 as a synonym for ''Pseudoarachniotus orissi'' and ''Aphanoascus orissi''. Description In culture, colonies of ''U. orissi'' are yellowish white in colour before darkening to buff or brownish-orange. Colonies are flat, dense and take on a woolly to coarsely powdery texture. ''U. orissi'' degrades keratin relatively quickly. ''U. orissi'' has a heterothallic mating system, requiring two compatible "sexes" for sexual reproduction to occur. It produces urease Ureases (), functionally, belong to the superfamily of amidohydrolases and phosphotriesterases.

Urease
Ureases (), functionally, belong to the superfamily of amidohydrolases and phosphotriesterases. Ureases are found in numerous bacteria, fungi, algae, plants, and some invertebrates, as well as in soils, as a soil enzyme. They are nickel-containing metalloenzymes of high molecular weight. These enzymes catalyze the hydrolysis of urea into carbon dioxide and ammonia: : (NH2)2CO + H2O CO2 + 2NH3 The hydrolysis of urea occurs in two stages. In the first stage, ammonia and carbamic acid are produced. The carbamate spontaneously and rapidly hydrolyzes to ammonia and carbonic acid. Urease activity increases the pH of its environment as ammonia is produced, which is basic. History Its activity was first identified in 1876 by Frédéric Alphonse Musculus as a soluble ferment. In 1926, James B. Sumner, showed that urease is a protein by examining its crystallized form. Sumner's work was the first demonstration that a protein can function as an enzyme and led eventually to the reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onygenales
The Onygenales are an order of fungi in the class Eurotiomycetes and division Ascomycota. The order's last common ancestor is estimated to have lived 150 million years ago. Onygenales can consume and break down keratin, the main component of the outer layer of skin. They are primarily found on animals, droppings, and areas frequented by animals. Many are dimorphic, and can change from mold to yeast form depending on their environment. Many onygenalean fungi are pathogens. One species, ''Trichophyton rubrum'', is the primary cause of athlete's foot. This order also includes Coccidioides implicated in Valley fever. The Onygenales are important as emerging human pathogens because of the rising rates of immunosuppression due to live-organ transplant, HIV/AIDS, and autoimmune disorders such as lupus erythematosus Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. Symptoms of these disease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
