Mold Diverse group of fungi

A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts.

Zygomycota paraphyletic group of fungi

Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla the Mucoromycota and Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycete hyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae. Zygomycota is no longer recognised as it was not believed to be truly monophyletic.

Zygomycosis

Zygomycosis is the broadest term to refer to infections caused by bread mold fungi of the zygomycota phylum. However, because zygomycota has been identified as polyphyletic, and is not included in modern fungal classification systems, the diseases that zygomycosis can refer to are better called by their specific names: mucormycosis, phycomycosis and basidiobolomycosis. These rare yet serious and potentially life-threatening fungal infections usually affect the face or oropharyngeal cavity. Zygomycosis type infections are most often caused by common fungi found in soil and decaying vegetation. While most individuals are exposed to the fungi on a regular basis, those with immune disorders (immunocompromised) are more prone to fungal infection. These types of infections are also common after natural disasters, such as tornadoes or earthquakes, where people have open wounds that have become filled with soil or vegetative matter.

<i>Rhizopus</i> Genus of fungi

Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances , including "mature fruits and vegetables", jellies, syrups, leather, bread, peanuts, and tobacco. They are multicellular. Some Rhizopus species are opportunistic agents of human zygomycosis and can be fatal. Rhizopus infections may also be a complication of diabetic ketoacidosis. This widespread genus includes at least eight species.

Mucorales order of fungi

The Mucorales is the largest and best studied order of zygomycete fungi. Members of this order are sometimes called pin molds. The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales.

<i>Mucor</i> Genus of fungi

Mucor is a microbial genus of approximately 40 species of moulds commonly found in soil, digestive systems, plant surfaces, some cheeses like tomme de savoie, rotten vegetable matter and iron oxide residue in the biosorption process.

Latridiidae Family of beetles

Latridiidae is a family of tiny, little-known beetles commonly called minute brown scavenger beetles or fungus beetle. The number of described species currently stands at around 1050 in 29 genera but the number of species is undoubtedly much higher than this and increases each time a new estimate is made.

Pier Antonio Micheli Italian botanist

Pier Antonio Micheli was a noted Italian botanist, professor of botany in Pisa, curator of the Orto Botanico di Firenze, author of Nova plantarum genera iuxta Tournefortii methodum disposita. He discovered the spores of mushrooms, was a leading authority on cryptogams, and coined several important genera of microfungi including Aspergillus and Botrytis.

<i>Mucor mucedo</i> species of fungus

Mucor mucedo, commonly known as the common pinmould, is a fungal plant pathogen and member of the phylum Zygomycota and the genus Mucor. Commonly found on soil, dung, water, plants and moist foods, Mucor mucedo is a saprotrophic fungus found world-wide with 85 known strains. It is often mistaken for Rhizopus rots on fruits due to similar mould growth shape and colour. Contrastingly, however, Mucor mucedo is found to grow on a wide range of stored grains and plants, including cucumber and tomato. Discovered in Italy in 1729 by P.A. Micheli and later noted by Carl Linnaeus in 1753 in the Species Plantarum, Mucor mucedo was originally classified as Mucor vulgaris by Micheli but later classified synonymous under name Mucor mucedo. The species was redescribed as Ascophora mucedo by H.J. Tode in 1790 but this type resided in a stoloniferous habitat and was later made the type of new genus Rhizopus.

Fermentation starter preparation to assist the beginning of the fermentation process in preparation of various foods and fermented drinks

A fermentation starter is a preparation to assist the beginning of the fermentation process in preparation of various foods and alcoholic drinks. A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation.

Phycomycetes is an obsolete polyphyletic taxon for certain fungi with aseptate hyphae. It is used in the Engler system.

Rhizomucor is a genus of fungi in the Mucoraceae family. The widespread genus contains six species. Rhizomucor parasiticus, the species originally selected as the type, is now considered synonymous with Rhizomucor pusillus.

M. indicus is among the most important members of zygomycetes fungi. This dimorphic fungus is capable of production of several valuable products. Some strains of the fungus have been isolated from the traditional Indonesian food tempeh. M. indicus is nowadays used for production of several homemade food and beverages especially in Asia. This has also been successfully used as a safe nutritional source for fish and rat. The fungus is generally regarded as safe though there are few reports claiming that this is a pathogenic fungus.

<i>Spinellus fusiger</i> species of fungus

Spinellus fusiger, commonly known as the bonnet mold, is a species of fungus in the Zygomycota phylum. It is a pin mold that is characterized by erect sporangiophores that are simple in structure, brown or yellowish-brown in color, and with branched aerial filaments that bear the zygospores. It grows as a parasitic mold on mushrooms, including several species from the genera Mycena, including M. haematopus, M. pura, M. epipterygia, M. leptocephala, and various Collybia species, such as C. alkalivirens, C. luteifolia, C. dryophila, and C. butyracea. It has also been found growing on agaric species in Amanita, Gymnopus, and Hygrophorus.

Rhizomucor miehei is a species of fungus. It is commercially used to produce enzymes which can be used to produce a microbial rennet to curd milk and produce cheese.......

Agricultural microbiology is a branch of microbiology dealing with plant-associated microbes and plant and animal diseases. It also deals with the microbiology of soil fertility, such as microbial degradation of organic matter and soil nutrient transformations.

, qūniè, jiǔqū, or jiǔmǔ is a type of East Asian dried fermentation starter grown on a solid medium and used in the production of traditional Chinese alcoholic beverages. The Chinese character 曲/麹 is romanised as in pinyin, chhu or chu in other transcription systems. The literal translation of jiǔqū is "liquor ferment", although "liquor mold" or "liquor starter" are adequate descriptions.

<i>Apophysomyces variabilis</i> species of fungus

Apophysomyces variabilis is an emerging fungal pathogen that can cause serious and sometimes fatal infection in humans. This fungus is a soil-dwelling saprobe with tropical to subtropical distribution. It is a zygomycete that causes mucormycosis, an infection in humans brought about by fungi in the order Mucorales. Infectious cases have been reported globally in locations including the Americas, Southeast Asia, India, and Australia. Apophysomyces variabilis infections are not transmissible from person to person.

<i>Rhizopus oryzae</i> species of fungus

Rhizopus oryzae is a filamentous heterothallic microfungus that occurs as a saprotroph in soil, dung, and rotting vegetation. This species is very similar to Rhizopus stolonifer, but it can be distinguished by its smaller sporangia and air-dispersed sporangiospores. It differs from R. oligosporus and R. microsporus by its larger columellae and sporangiospores. R. oryzae is used economically in the production of the enzymes, glucoamylase and lipase, in the synthesis of organic acids, and in various fermented foods. The many strains of R. oryzae produce a wide range of enzymes such as carbohydrate digesting enzymes and polymers along with a number of organic acids, ethanol and esters giving it useful properties within the food industries, bio-diesel production, and pharmaceutical industries. It is also an opportunistic pathogen of humans causing mucormycosis.

<i>Rhizopus stolonifer</i> species of fungus

Rhizopus stolonifer is commonly known as black bread mold. It is a member of Zygomycota and considered the most important species in the genus Rhizopus. It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions. It is a common agent of decomposition of stored foods. Like other members of the genus Rhizopus, R. stolonifer grows rapidly, mostly in indoor environments.
