This study compared cultural and analytical methods for detecting aflatoxin production by Aspergillus species. Aspergillus isolates were obtained from various Mississippi Delta crops (corn, peanut, rice, cotton) and soils. Most of the isolates (99%) were A. flavus and the remainder comprised A. parasiticus and A. nomius. The following three cultural methods were evaluated on potato dextrose agar: fluorescence (FL) on beta-cyclodextrin-containing media (CD), yellow pigment (YP) formation in…

A rapid identification method for aflatoxin-producing strains ofAspergillus flavus andA. parasiticus by ammonia vapor

The colony reverse of aflatoxin (AF)-producing strains of Aspergillus flavus and A. parasiticus turned pink when their cultures were exposed to ammonia vapor and this method was useful for rapid screening the AF-producing strains.

Direct visual detection of aflatoxin synthesis by minicolonies of Aspergillus species

Both of these strains showed variation for toxin synthesis among their respective progeny, and specific progeny showed a good correlation for aflatoxin synthesis when examined by the two procedures.

Comparison of two immunochemical methods with thin-layer chromatographic methods for determination of aflatoxins.

Three different methods were compared for the determination of total flatoxins in corn and peanuts naturally contaminated with aflatoxins and in corn, peanuts, cottonseed, peanut butter, and poultry

Aflatoxin production by Aspergillus flavus isolates pathogenic to coconut insect pests

Of all the seven media used for AT detection, CCMPA (10%) was found to be the best one, followed by 20%CCMPA, for direct and rapid AT Detection, and AT production was not necessary for pathogenicity in the insects.
