Joffe's professional interests were centered primarily in toxigenic fungi associated with production of mycotoxins (aflatoxins, trichothecenes, and other toxins); ecology and environmental factors favoring formation and distribution of Fusarium mycotoxins in cereal grains, feeds and foods; and phytotoxic action of Fusarium strains, and their toxicity in animals and humans.
Ochratoxin A (OTA), a mycotoxin produced by A. ochraceus, contaminates food and initiates apoptosis of plant cells.
Ochratoxin A, a toxin produced by Aspergillus ochraceus, Aspergillus carbonarius and Penicillium verrucosum, is one of the most abundant food-contaminating mycotoxins.
Exposure to the mycotoxins present in Stachybotrys chartarum or Stachybotrys atra can have a wide range of effects.
Trichothecenes are a very large family of chemically related mycotoxins produced by various species of Fusarium, Myrothecium, Trichoderma, Trichothecium, Cephalosporium, Verticimonosporium, and Stachybotrys.
It is a mycotoxin, derived from fungi in the Fusarium family, and may be found as a contaminant in fungus-infected crops.
