(A) Southern analysis of strains 86 (lane 1), 86-10 (lane 2), and 86D (lane 3). (B) Aflatoxin concentrations in strains 86-10 and 86D. Cultures were grown for 5 days in PDB at 28°C. Genomic DNA was extracted and digested with BamHI and probed by using an aflJ radioactive probe. The aflatoxin concentrations in culture media were determined by ELISA.
