Abstract
Many microorganisms produce low molecular weight compounds called secondary metabolites whose benefit to the producing organism is often obscure (Bu’Lock 1961). Fungi are among the most prodigious producers of secondary metabolites, many of which are either beneficial (e.g. antibiotics) or detrimental (e.g., mycotoxins) to humans. Two chemically related fungal secondary metabolites that have been studied extensively are the mycotoxins sterigmatocystin (ST) and aflatoxin (AF), produced by several Aspergillus species. AF was discovered in the 1960s when thousands of fowl died of a mysterious disease called “Turkey-X” disease (Lancaster et al. 1961). Later, it was found that Turkey-X disease was not actually caused by a pathogen but rather was a poisoning stemming from contaminated peanut meal in the feed that had been colonized by a fungus identified as A. flavus (Lancaster et al. 1961).
