Lycoperdon umbrinum, commonly known as the umber-brown puffball, is a type of Puffball mushroom in the genus Lycoperdon. It is found in China, Europe, Africa, and North America.
Pestalotiopsis microspora is a species of endophytic fungus capable of breaking down and digesting polyurethane. Originally identified in 1880 in fallen foliage of common ivy in Buenos Aires, it also causes leaf spot in Hypericum 'Hidcote' shrubs in Japan.
Aspergillus ochraceus is a mold species in the genus Aspergillus known to produce the toxin ochratoxin A, one of the most abundant food-contaminating mycotoxins, and citrinin. It also produces the dihydroisocoumarin mellein. It is a filamentous fungus in nature and has characteristic biseriate conidiophores. Traditionally a soil fungus, has now began to adapt to varied ecological niches, like agricultural commodities, farmed animal and marine species. In humans and animals the consumption of this fungus produces chronic neurotoxic, immunosuppressive, genotoxic, carcinogenic and teratogenic effects. Its airborne spores are one of the potential causes of asthma in children and lung diseases in humans. The pig and chicken populations in the farms are the most affected by this fungus and its mycotoxins. Certain fungicides like mancozeb, copper oxychloride, and sulfur have inhibitory effects on the growth of this fungus and its mycotoxin producing capacities.
Aspergillus sydowii is a pathogenic fungus that causes several diseases in humans. It has been implicated in the death of sea fan corals in the Caribbean Sea.
Cerevisterol (5α-ergosta-7,22-diene-3β,5,6β-triol) is a sterol. Originally described in the 1930s from the yeast Saccharomyces cerevisiae, it has since been found in several other fungi and, recently, in deep water coral. Cerevisterol has some in vitro bioactive properties, including cytotoxicity to some mammalian cell lines.
Throughout human history, fungi have been utilized as a source of food and harnessed to ferment and preserve foods and beverages. In the 20th century, humans have learned to harness fungi to protect human health, while industry has utilized fungi for large scale production of enzymes, acids, and biosurfactants. With the advent of modern nanotechnology in the 1980s, fungi have remained important by providing a greener alternative to chemically synthesized nanoparticle.
Fumigaclavine A is an antibacterial ergoline alkaloid produced by endophytic Aspergillus.
Fellutamides are tripeptide derivatives from Penicillium fellutanum and other fungi. They are potent proteasome inhibitor that stimulates nerve growth factor synthesis in vitro.
Arugosin C is an anthraquinone derivative isolated from a species of Aspergillus found in the Red Sea.
Evariquinone is a chemical compound of the anthraquinone class which has been isolated from a sponge-derived strain of the fungus Emericella variecolor and from Aspergillus versicolor.
(-)-Versicolamide B and (+)-Versicolamide B are spiroindole alkaloids isolated from the fungus Aspergillus that belong to a class of naturally occurring 2,5-diketopiperazines. The versicolamides are structurally complex spiro-cyclized versions of prenylated cyclo(L-Trp-L-Pro) derivatives which possess a unique spiro-fusion to a pyrrolidine at the 3-position of the oxindole core together with the bicyclo[2.2.2]diazaoctane ring system. While (-)-versicolamide B was isolated from the marine fungus Aspergillus sp. the enantiomer (+)-versicolamide B was isolated from the terrestrial fungi Aspergillus versicolor NRRL. The total asymmetric syntheses of both enantiomers have been achieved and the implications of their biosynthesis have been investigated.
Fumiquinazolines are bio-active isolates of Aspergillus.
Pseurotin A is a secondary metabolite of Aspergillus.
14-Norpseurotin A is an alkaloid and a bio-active metabolite of Aspergillus, featuring an oxa-spiro-lactam core.
Aspergillus versicolor is a slow-growing species of filamentous fungus commonly found in damp indoor environments and on food products. It has a characteristic musty odor associated with moldy homes and is a major producer of the hepatotoxic and carcinogenic mycotoxin sterigmatocystin. Like other Aspergillus species, A. versicolor is an eye, nose, and throat irritant.
Fungal isolates have been researched for decades. Because fungi often exist in thin mycelial monolayers, with no protective shell, immune system, and limited mobility, they have developed the ability to synthesize a variety of unusual compounds for survival. Researchers have discovered fungal isolates with anticancer, antimicrobial, immunomodulatory, and other bio-active properties. The first statins, β-Lactam antibiotics, as well as a few important antifungals, were discovered in fungi.
Penicillium chermesinum is an anamorph fungus species of the genus of Penicillium which was isolated from soil from Nova Scotia in Canada.Penicillium chermesinum produces plastatin, luteosporin, xanthomegnin, azaphilones, p-terphenyls and costaclavine.
Aspergillus tubingensis is a darkly pigmented species of fungus in the genus Aspergillus section Nigri. It is often confused with Aspergillus niger due to their similar morphology and habitat. A. tubingensis is often involved in food spoilage of fruits and wheat, and industrial fermentation. This species is a rare agent of opportunistic infection.
Aspergillus lucknowensis is a species of fungus in the genus Aspergillus. It is from the Usti section. The species was first described in 1968.
Aspergillus carneus is a fast-growing, filamentous fungus found on detritus and in fertile soil worldwide. It is characterized by its yellow, thick-walled hyphae and biseriate sterigmata. The fungus produces citrinin and 5 unique depsipeptides, Aspergillicins A-E.
