Aspergillus

Genus of molds with around 200 species (species). The name derives from the very concise appearance of the fungus under the microscope, which is reminiscent of the Aspergill (holy water fronds) or a Gießkannenkopf when pouring (leaking water). Therefore, sometimes the term watering can mold is used. The Aspergilli are found in almost all oxygen-rich environments occurring aerobic creatures. As a rule, they grow on carbohydrate-rich substrates, especially on glucose (Glucose). Therefore, sugar-rich grapes are particularly susceptible to grape rot, for which, among other things, the species Aspergillus absidia shows responsible. The species Aspergillus niger (black mold) is used for the production of the enzymes used in winemaking lysozyme and pectinases, In the food industry this is used for the production of citric acid used. The species Aspergillus oryzae serves as fermentation agents in the production of rice wine, Some types form through metabolic processes mycotoxins (Fungal toxins) and are pathogenic (pathogenic) for humans allergies and infections. Such are for example aflatoxin B1, Ochratoxin A and patulin The latter two may be contained in grapes and wine.
