Who discovered Aspergillus niger?

Aspergillus was named by Pier Antonio Micheli, an Italian priest and biologist in 1729 when cataloging molds. The molds resembled an aspergillum, a holy water sprinkler (from Latin Spargere-to sprinkle). In 1863 the species fumigatus was first described by physician Georg W. Fresenius.

Is Aspergillus niger unicellular or multicellular?

niger, is fundamentally very different from growth of bacteria and yeasts. Whereas bacteria and yeasts are unicellular organisms that multiply by cell division, filamentous fungi are multicellular organisms that form a large and dynamic mycelial network consisting of interconnected hyphae.

What is obtained from Aspergillus niger?

Aspergillus niger is a fungal microbe of great industrial importance. This mold is used extensively in the production of citric acid and in the production of several enzymes such as amylases, pectinases, and proteases (Godfrey and West, 1996).

Where is Aspergillus versicolor found?

It is commonly found in soil and decaying organic matter, and has been known to develop on many kinds of food, including cereal grains, seeds, nuts, dried meats and dairy products [1]. It can frequently be found indoors, particularly on water-damaged buildings or materials such as wallpaper, carpets and insulation.

Is Aspergillus niger black mold?

The fungus Aspergillus niger is a type of mould, which can sometimes be attributed to the cause of some cases of pneumonia. It is also the causative agent of ‘black mould’ on the outsides of certain foods, such as apricots, onions, grapes, etc – therefore making Aspergillus niger a food ‘spoilage’ organism.

What disease does Aspergillus cause?

Aspergilloma is a growth (fungus ball) that develops in an area of past lung disease or lung scarring such as tuberculosis or lung abscess. Invasive pulmonary aspergillosis is a serious infection with pneumonia. It can spread to other parts of the body.

Which disease of onion is caused by Aspergillus niger?

Aspergillus niger causes several diseases including black mold (or black rot) of onions and garlic, crown rot of peanuts, and vine canker of table grapes. In black rot of onions and garlic, A. niger develops between the outer (dead, flaky) skin and the first fleshy scales of the bulb which become water soaked.

Allergic aspergillosis typically heals with treatment. You may get it again if you’re repeatedly exposed to the fungus. Recovering from invasive aspergillosis depends on your overall health and the strength of your immune system. Aspergilloma often requires no treatment.

What disease does Aspergillus niger cause in humans?

Aspergillosis is an infection caused by Aspergillus, a common mold (a type of fungus) that lives indoors and outdoors. Most people breathe in Aspergillus spores every day without getting sick.

What product can eliminate the aspergillus?

Using Chemical Disinfectants to Kill Aspergillus Niger. Use alcohol to disinfect surfaces. A 70% alcohol solution is an effective way to kill Aspergillus. Alcohol is an effective fungicide because it is able to penetrate the cell walls and spores of Aspergillus niger, killing it in the process.

How do I get rid of aspergillus?

Antifungal medications. These drugs are the standard treatment for invasive pulmonary aspergillosis. The most effective treatment is a newer antifungal drug, voriconazole (Vfend). Amphotericin B is another option. All antifungal drugs can have serious side effects, including kidney and liver damage.
