Aspergillus petersonii is a species of fungus in the genus Aspergillus which has been isolated from an office environment. [1] [3]
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper.
Aflatoxins are various poisonous carcinogens and mutagens that are produced by certain molds, particularly Aspergillus species. The fungi grow in soil, decaying vegetation and various staple foodstuffs and commodities such as hay, sweetcorn, wheat, millet, sorghum, cassava, rice, chili peppers, cottonseed, peanuts, tree nuts, sesame seeds, sunflower seeds, and various spices. In short, the relevant fungi grow on almost any crop or food. When such contaminated food is processed or consumed, the aflatoxins enter the general food supply. They have been found in both pet and human foods, as well as in feedstocks for agricultural animals. Animals fed contaminated food can pass aflatoxin transformation products into eggs, milk products, and meat. For example, contaminated poultry feed is the suspected source of aflatoxin-contaminated chicken meat and eggs in Pakistan.
Aspergillus niger is a mold classified within the Nigri section of the Aspergillus genus. The Aspergillus genus consists of common molds found throughout the environment within soil and water, on vegetation, in fecal matter, on decomposing matter, and suspended in the air. Species within this genus often grow quickly and can sporulate within a few days of germination. A combination of characteristics unique to A. niger makes the microbe invaluable to the production of many acids, proteins and bioactive compounds. Characteristics including extensive metabolic diversity, high production yield, secretion capability, and the ability to conduct post-translational modifications are responsible for A. niger's robust production of secondary metabolites. A. niger's capability to withstand extremely acidic conditions makes it especially important to the industrial production of citric acid.
Aspergillus is a genus consisting of several hundred mold species found in various climates worldwide.
Fumonisin B2 is a fumonisin mycotoxin produced by the fungi Fusarium verticillioides and Aspergillus niger.
Aspergillosis is a fungal infection of usually the lungs, caused by the genus Aspergillus, a common mould that is breathed in frequently from the air around, but does not usually affect most people. It generally occurs in people with lung diseases such as asthma, cystic fibrosis or tuberculosis, or those who have had a stem cell or organ transplant, and those who cannot fight infection because of medications they take such as steroids and some cancer treatments. Rarely, it can affect skin.
Gliotoxin is a sulfur-containing mycotoxin that belongs to a class of naturally occurring 2,5-diketopiperazines produced by several species of fungi, especially those of marine origin. It is the most prominent member of the epipolythiopiperazines, a large class of natural products featuring a diketopiperazine with di- or polysulfide linkage. These highly bioactive compounds have been the subject of numerous studies aimed at new therapeutics. Gliotoxin was originally isolated from Gliocladium fimbriatum, and was named accordingly. It is an epipolythiodioxopiperazine metabolite.
Kluyveromyces lactis is a Kluyveromyces yeast commonly used for genetic studies and industrial applications. Its name comes from the ability to assimilate lactose and convert it into lactic acid.
Leptospermum petersonii, commonly known as lemon-scented teatree, is a species of shrub or small tree that is endemic to eastern Australia. It has thin, fibrous or flaky bark, often strongly-scented elliptic to lance-shaped leaves, white flowers and fruit that are retained for several years. It is commonly grown as an ornamental and is regarded as a minor environmental weed in some areas.
The fungi imperfecti or imperfect fungi, are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. They are known as imperfect fungi because only their asexual and vegetative phases are known. They have asexual form of reproduction, meaning that these fungi produce their spores asexually, in the process called sporogenesis.
In genetics, the gene density of an organism's genome is the ratio of the number of genes per number of base pairs, usually written in terms of a million base pairs, or megabase (Mb). The human genome has a gene density of 11-15 genes/Mb, while the genome of the C. elegans roundworm is estimated to have 200.
Aspergillus glaucus is a filamentous fungus which is known to have a wide environmental distribution due to its physiological hardiness under more extreme conditions. Like many other fungi belonging to the genus Aspergillus, it can be mildly pathogenic but has a number of useful potential applications in medicine and the production of foodstuffs.
Aspergillus unguis is a species of fungus in the genus Aspergillus, and the asexual state (anamorph) of Emericella unguis. Aspergillus unguis is a filamentous soil-borne fungus found on decomposing plant matter and other moist substrates including with building materials and household dust. Aspergillus unguis occurs mainly in tropical and subtropical soils but has also been isolated from various marine and aquatic habitats. The species was first isolated in 1935 by Weill and L. Gaudin. Historically, A. unguis was assigned to the A. nidulans group, a common group of soil-borne fungi due to the resemblance of its ascospores and cleistothecia to those of Emericella nidulans. Aspergillus unguis is distinctive, however, in possessing spicular hyphae. A number of synonyms have been collapsed into this species, including Sterigmatocystis unguis, Aspergillus laokiashanensis and Aspergillus mellinus.
Probergrothius angolensis, sometimes known as the Welwitschia bug, is a species of true bug found in the Namib desert and nearby regions.
Aspergillus sclerotiorum is a species of fungus in the genus Aspergillus. It is from the Circumdati section. The species was first described in 1933. A. sclerotiorum has been reported to produce penicillic acid, xanthomegnin, viomellein, and vioxanthin.
Aspergillus arenarioides is a species of fungus in the genus Aspergillus. It is from the Petersonii section. The species was first described in 2014.
Fumonisin B4 is a fumonisin mycotoxin produced mainly by the fungi Fusarium proliferatum, Fusarium verticillioides. Recently FB4 has been detected in fungi Aspergillus niger and in several Tolypocladium species.
Ajamxanthone is a chemical compound which is produced by the fungus Aspergillus stellatus. Ajamxanthone forms yellow needles. Its synonyms are (+)-ajamxanthone and CTK8I3902.
Aspergillus funiculosus is an anamorph species of fungus in the genus Aspergillus. Aspergillus funiculosus produces the funiculolides A-D and the antibiotic funicin.
