Aspergyllus niger (braziliensis)

É uma das espécies mais encontradas no solo.
OCHRATOXINAS: tem efeitos hepatotóxicos, nefrotoxicos, imunossupressores, teratogênicos e são a causa de tumores no trato urinário
A produção de ochratoxina pelo A. niger é muito baixa.
O Aspergillus em ambientes indoor, são geralmente associados com inundações, vazamentos de canose tetos, condensação de sestemas HVAC, ou úmidade no chão ( fundamento) e banheiros.

Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus. It causes a disease called black mold on certain fruits and vegetables such as grapes, 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").[1]

Some strains of A. niger have been reported to produce potent mycotoxins called ochratoxins,[2] but 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.[1][3]
