Species/Subspecies: Aspergillus ochraceus
Categories: Of practical use; spoilage organism
Etymology: Genus name: to scatter.
Species epithet: ocher-coloured.
Significance:  [Unclassified]   
Macromorphology (smell):
Aspergillus ochraceus 
Kolonier of A. ochraceus grow fast (about 50 mm in 7 days). Many nice pictures of A. ochraceus can be found in the reference below (no. 89).
Aspergillus ochraceusAspergillus ochraceus
The conidia are 2.5-3.5 µm in diameter.
Spec. Char.: Optimal temperature for growth is 25°C.
Disease/effect: Many more animal species than those listed in the table below can be affected by ochratoxicosis. Dogs are particularly sensitive, while ruminants are less sensitive.
Virulence Factors: Produces the mycotoxins ochratoxin A, citrinin och mellein (= dihydroisocoumarin).

Practical use:A. ochraceus produces many different enzymes, which can have industrial importance, e.g. hydrolases, proteases, tannases, oxidases and cellulases (see ref. 91 below).
Comment:In terms of ochratoxin production, Aspergillus alliaceus appears to be more important on at least some substrates than A. ochraceus (see ref. 90 below).
