Varixanthone is an antimicrobial made by the marine fungus Emericella variecolor . [2]
Aspergillus nidulans is one of many species of filamentous fungi in the phylum Ascomycota. It has been an important research organism for studying eukaryotic cell biology for over 50 years, being used to study a wide range of subjects including recombination, DNA repair, mutation, cell cycle control, tubulin, chromatin, nucleokinesis, pathogenesis, metabolism, and experimental evolution. It is one of the few species in its genus able to form sexual spores through meiosis, allowing crossing of strains in the laboratory. A. nidulans is a homothallic fungus, meaning it is able to self-fertilize and form fruiting bodies in the absence of a mating partner. It has septate hyphae with a woolly colony texture and white mycelia. The green colour of wild-type colonies is due to pigmentation of the spores, while mutations in the pigmentation pathway can produce other spore colours.
A depside is a type of polyphenolic compound composed of two or more monocyclic aromatic units linked by an ester group. Depsides are most often found in lichens, but have also been isolated from higher plants, including species of the Ericaceae, Lamiaceae, Papaveraceae and Myrtaceae.
Marine fungi are species of fungi that live in marine or estuarine environments. They are not a taxonomic group, but share a common habitat. Obligate marine fungi grow exclusively in the marine habitat while wholly or sporadically submerged in sea water. Facultative marine fungi normally occupy terrestrial or freshwater habitats, but are capable of living or even sporulating in a marine habitat. About 444 species of marine fungi have been described, including seven genera and ten species of basidiomycetes, and 177 genera and 360 species of ascomycetes. The remainder of the marine fungi are chytrids and mitosporic or asexual fungi. Many species of marine fungi are known only from spores and it is likely a large number of species have yet to be discovered. In fact, it is thought that less than 1% of all marine fungal species have been described, due to difficulty in targeting marine fungal DNA and difficulties that arise in attempting to grow cultures of marine fungi. It is impracticable to culture many of these fungi, but their nature can be investigated by examining seawater samples and undertaking rDNA analysis of the fungal material found.
Emericella discophora is a fungus. Its ascospores produce wide and entire, nonstellate equatorial crests. It was isolated from soil in Spain.
Emericella filifera is a fungus. Its ascospores form long appendages that emerge radially from narrow stellate crests. It was isolated from raisins in Argentina.
Emericella olivicola is a fungus. Its ascospores have star-shaped equatorial crests. It was isolated from olives in Italy.
Emericella stella-maris is a fungus. Its ascospores have star-shaped equatorial crests. It was isolated from leaf litter in Tunisia.
Emericella is a former genus of fungi.
Isoemericellin is a chemical compound isolated from the marine fungus Emericella variecolor.
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.
Aspergillus ustus is a microfungus and member of the division Ascomycota. It is commonly found in indoor environments and soil. Isolated cases of human infection resulting from A. ustus have been described; however the majority of these are nail infections.
1-Hydroxyphenanthrene is a phenanthrol and a human metabolite of phenanthrene that can be detected in urine of persons exposed to PAHs.
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.
Aspergillus desertorum is a species of fungus in the genus Aspergillus which has been isolated from desert soil. It is from the Nidulantes section. Aspergillus desertorum produces desertorin A, desertorin B, desertorin C, paxiline and emindol DA.
Aspergillus multicolor is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1954. It was isolated from forest soil in Somalia. It has been shown to produce asticolourin A-C, averufin, 5,6-dimethoxydihydrosterigmatocystin, 5,6-dimethoxysterigmatocystin, sterigmatocystin, and versicolourin C.
Aspergillus navahoensis is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 1982. It was isolated from sand in Arizona, United States. It has been reported to produce averufin, norsolorinic acid, 6,7,8-trihydroxy-3-methylisocoumarin, desferritriacetylfusigen, echinocandin B, and sterigmatocystin.
Aspergillus fructiculosus is a species of fungus in the genus Aspergillus. The species was first described in 1965. It has been reported to produce sterigmatocystin.
Aspergillus dimorphicus is a species of fungus in the genus Aspergillus. It is from the Cremei section. The species was first described in 1969. It has been reported to produce wentilactones.
Aspergillus filifer is a species of fungus in the genus Aspergillus. It is from the Nidulantes section. The species was first described in 2008. It has been reported to produce shamixanthones and varitriol.
Guisinol is an antibacterial depside with the molecular formula C23H25ClO5 that has been isolated from the fungus Aspergillus unguis.
