TLDR
A unique method is described by which large yields of secondary metabolites arc produced on solid substrates using Aspergillus and Penicillium species, which prevents sporulation of the fungus and makes recovery of the product easier than in conventional liquid media.Abstract:
A unique method is described by which large yields of secondary metabolites arc produced on solid substrates. The process involves the use of moist substrates which are continuously agitated in appropriate fermentation equipment. The amount of agitation, aeration, and moisture can be varied. Extremely high yields of secondary metabolites such as ochratoxin and aflatoxin were obtained using Aspergillus and Penicillium species. The process prevents sporulation of the fungus and because of the nature of the solid substrate makes recovery of the product easier than in conventional liquid media. The substrates include rice, corn, wheat, and other cereals.read more

Production of aflatoxin on wheat and oats: measurement with a recording densitometer.
TL;DR: A densitometric method for reading thin-layer chromatographic plates is described; this is more objective and more accurate than the visual methods previously used for the determination of all four aflatoxins.
