  • Title: Aflatoxin-producing strains of Aspergillus flavus detected by fluorescence of agar medium under ultraviolet light.
    Author: Hara S, Fennell DI, Hesseltine CW.
    Journal: Appl Microbiol; 1974 Jun; 27(6):1118-23. PubMed ID: 4208639.
    Abstract:
    The fluorescence method of detecting aflatoxin-producing strains of Aspergillus flavus and related species utilizes the ultraviolet-induced fluorescence of aflatoxin produced in a modified Czapek's solution agar containing corn steep liquor, HgCl(2), and (NH(4))H(2)PO(4) instead of NaNO(3). The presence of aflatoxin is confirmed by thin-layer chromatography of CHCl(3) extracts of the fluorescing agar.
