Aspergillus niger can cause black mold infections in certain legumes, fruits, and vegetables such as peanuts, grapes, and onions, leading to the fungus being a common food contaminant. This filamentous ascomycete has a tolerance to changes in pH , humidity , and heat, thriving in a temperature range from 15 to 53 °C (59 to 127 °F). [ 45 ]
The main target organ in mammals is the liver, so aflatoxicosis primarily is a hepatic disease. Conditions increasing the likelihood of aflatoxicosis in humans include limited availability of food, environmental conditions that favour mould growth on foodstuffs, and lack of regulatory systems for aflatoxin monitoring and control.

In addition to growth on carbon sources, many species of Aspergillus demonstrate oligotrophy where they are capable of growing in nutrient-depleted environments, or environments with a complete lack of key nutrients. Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation ...
Aspergillus niger on MEAOX-Agar Aspergillus tubingensis on Czapek-Agar. Black kōji produces citric acid during fermentation, which inhibits the growth of unwanted microorganisms. [2] It is typically used for the production of Awamori. [2] [12] There are three Aspergillus species that are used as black kōji: [2]
In dogs, aspergillosis is an uncommon disease typically affecting only the nasal passages (nasal aspergillosis). This is much more common in dolicocephalic breeds . It can also spread to the rest of the body; this is termed disseminated aspergillosis and is rare, usually affecting individuals with underlying immune disorders.
According to the NOVA classification system, ultra-processed foods are industrial formulations made entirely or mostly from substances extracted from foods (oils, fats, sugar, starch, and proteins ...
Aspergillus tubingensis growing on Czapek medium. Czapek medium, also called Czapek's agar (CZA) [1] [2] or Czapek-Dox medium, is a growth medium for propagating fungi and other organisms in a laboratory. It was named after its inventors, Czech botanist Friedrich Johann Franz Czapek (May 16, 1868 – July 31, 1921) and American chemist Arthur ...
Aspergillus sp. growing in potato dextrose agar Potato dextrose agar (BAM Media M127) and potato dextrose broth are common microbiological growth media made from potato infusion and dextrose. Potato dextrose agar (abbreviated "PDA") is the most widely used medium for growing fungi and bacteria. PDA has the capability to culture various bacteria and fungi found in the soil. This agar can be ...
