Emericella Variecolor
''Emericella'' is a genus of fungi. The genus name of ''Emericella'' is in honour of Emeric Streatfield Berkeley (1834 - 1898), a British Lieutnant/Major General who served in India. He was also a botanist. Bio-active isolates called stromemycin have been found in marine ''Emericella''. Stromemycin is a C-glycosidic depside matrix metalloproteinase inhibitor.

Anthraquinone
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula . Isomers include various quinone derivatives. The term anthraquinone however refers to the isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring. It is a building block of many dyes and is used in bleaching pulp for papermaking. It is a yellow, highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. It is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol. It is found in nature as the rare mineral hoelite. Synthesis There are several current industrial methods to produce 9,10-anthraquinone: # The oxidation of anthracene. Chromium(VI) is the typical oxidant. # The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl3. o-Benzoylbenzoic acid is an intermediate. This reaction is useful for produci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspergillus Versicolor
''Aspergillus versicolor'' is a slow-growing 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. Taxonomy The fungus was first described by Jean-Paul Vuillemin in 1903 under the name ''Sterigmatocystis versicolor'', and was later moved to the genus ''Aspergillus'' by Carlo Tiraboschi in 1908. Presently, the genus ''Sterigmatocystis'' is obsolete. Ecology ''Aspergillus versicolor'' is a highly ubiquitous species commonly isolated from soil, plant debris, marine environments, and indoor air environments. It is among the most common of indoor molds, often reported in dust and in water-damaged building materials, such as wallboards, insulation, textiles, ceiling tiles, and manufactured wood.
