Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus. It causes black mould on certain types of fruit and vegetables, and is a common contaminant of food.

Disease risks

Aspergillus niger is less likely to cause disease than some other Aspergillus species, but if large amounts of the spores are breathed in, the serious lung disease aspergillosis can occur. Aspergillosis is particularly frequent among horticultural workers breathing in peat dust which can be rich in Aspergillus spores. It is less harmful, though not entirely free from risks, if eaten and digested.

Uses

Aspergillus niger is cultured for the industrial production of some chemical compounds. Various strains of A. niger are used in the industrial preparation of citric acid (E330), gluconic acid (E574) and the enzymes glucoamylase and α-galactosidase (Beano®, Bean-zyme™), and have been assessed as acceptable for daily intake by the World Health Organisation.
