It causes a disease called black mould on certain fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food. It is ubiquitous in soil and is commonly reported from indoor environments, where its black colonies can be confused with those of Stachybotrys (species of which have also been called "black mould").
Some strains of A. niger have been reported to produce potent mycotoxins called ochratoxins; other sources disagree, claiming this report is based upon misidentification of the fungal species. Recent evidence suggests some true A. niger strains do produce ochratoxin A. It also produces the isoflavone orobol.
A. niger is included in Aspergillus subgenus Circumdati, section Nigri. The section Nigri includes 15 related black-spored species that may be confused with A. niger, including A. tubingensis, A. foetidus, A. carbonarius, and A. awamori. A number of morphologically similar species were recently described by Samson et al.
Recently the strain of ATCC 16404 Aspergillus niger has been reclassified at Aspergillus brasiliensis (refer to publication by Varga et al.). This has required an update to the U.S. Pharmacopoeia and the European Pharmacopoeia which commonly use this strain throughout the pharmaceutical industry.
A. niger causes black mold of onions and ornamental plants. Infection of onion seedlings by A. niger can become systemic, manifesting only when conditions are conducive. A. niger causes a common postharvest disease of onions, in which the black conidia can be observed between the scales of the bulb. The fungus also causes disease in peanuts and in grapes.
Human and animal disease
A. niger is less likely to cause human disease than some other Aspergillus species. In extremely rare instances, humans may become ill, but this is due to a serious lung disease, aspergillosis, that can occur. Aspergillosis is, in particular, frequent among horticultural workers that inhale peat dust, which can be rich in Aspergillus spores. It has been found in the mummies of ancient Egyptian tombs and can be inhaled when they are disturbed.
A. niger is cultured for the industrial production of many substances. Various strains of A. niger are used in the industrial preparation of citric acid (E330) and gluconic acid (E574) and have been assessed as acceptable for daily intake by the World Health Organisation. A. niger fermentation is "generally recognized as safe" (GRAS) by the United States Food and Drug Administration under the Federal Food, Drug, and Cosmetic Act.
Many useful enzymes are produced using industrial fermentation of A. niger. For example, A. niger glucoamylase is used in the production of high fructose corn syrup, and pectinases are used in cider and wine clarification. Alpha-galactosidase, an enzyme that breaks down certain complex sugars, is a component of Beano and other products that decrease flatulence. Another use for A. niger within the biotechnology industry is in the production of magnetic isotope-containing variants of biological macromolecules for NMR analysis. The enzyme Protease is derived from Aspergillus niger and used to produce the additive Clarity-Ferm. This product is being used in the brewing industry to reduce gluten content of wheat and barley based beers. A Clarity-Ferm treated beer made from barley or wheat usually tests below 20 ppm of gluten, the current international standard for gluten free.
Aspergillus niger growing from gold mining solution contained cyano metal complexes; such as gold, silver, copper iron and zinc. The fungus also plays a role in the solubilization of heavy metal sulfides. Alkali treated Aspergillus niger binds to silver to 10% of dry weight. Silver biosorbtion occurs via stoichiometric exchange with Ca(II) and Mg(II) of the sorbent.
A. niger is also cultured for the extraction of the enzymes glucose oxidase (GO) and Alpha-galactosidase (AGS). Glucose oxidase is used in the design of glucose biosensors, due to its high affinity for β-D-glucose. Alpha-galactosidase can be produced by A. niger fermentation; it is used to hydrolyze alpha 1-6 bonds found in melibiose, raffinose, and stachyose.
Research published in 2006–2008 investigated A. niger prolyl endoprotease (AN-PEP), a microbial-derived prolyl endoprotease which cleaves gluten. This has strong implications in the treatment of coeliac disease or other metabolic gluten sensitivity disease processes. A placebo controlled, double blind study was initiated in December 2008 to determine the efficacy of this enzyme in treating humans with coeliac disease.
A. niger is often used as a challenge organism for cleaning validation studies performed within sterile manufacturing facilities.
