Species/Subspecies: Aspergillus niger
Categories: Animal pathogen; human pathogen; spoilage organism
Etymology: Genus name: to scatter.
Species epithet: black.
Common name: Svartmögel
Significance:A. niger is found all over the world, but is less important as a pathogen in veterinary and human medicine. However, it is important as a spoilage organism.
  [Of minor importance]   
Macromorphology (smell):
Aspergillus niger Aspergillus niger Aspergillus niger 
The colonies are initially white, but the colour turns black after a few days when conidia spores begin to form. The colonies grow all over the plate.
Aspergillus nigerAspergillus niger
The conidial spores are dark brown in color and 4-5 µm in diameter.
Metabolism: Aspergillus spp. are aerobic and chemorganotrophic organisms. They are extremely important in degrading organic matter in nature. A. niger is thermotolerant.
Spec. Char.:
Reservoir: Can be found everywhere in soil.
Disease/effect: Aspergillosis is usually caused by A. fumigatus, but in rare cases A. niger, A.flavus, A. nidulans and A. terreus etc., may also be the causative agent.
