Figures & data
Table 1. Identification (ID) of sampled fungi based on morphology and ITS sequence analysis
Figure 1. Macromorphology images for each isolate using various media (top image), with corresponding micromorphology based on 40× magnification (bottom image). Images are shown in numerical order from SF1 (top left) to SF18 (bottom right).
Table 2. Aflatoxin chemotype profiles for sampled Aspergillus flavus isolates
Figure 3. TLC plate showing the presence of CPA for each Aspergillus flavus isolate sampled. This is the same TLC plate as shown in , except that this plate has been sprayed with a mixture of 1% dimethyl-aminobenzaldehyde in ethanol, followed by sulphuric acid:ethanol (1:1), then drying the spray solution on the plate with a heat gun.
Figure 2. TLC plate showing fluorescence of B and G aflatoxins under long-wave UV illumination (365 nm). The aflatoxin bands are noted on the right side of the image. These bands correspond to the AF standard lane noted at the bottom right of the image. The CPA standard, which does not fluoresce under UV, is noted on the bottom left lane. Between both standard lanes are the Aspergillus flavus isolates sampled.
