Aspergillus flavus parasiticus

Aspergillus flavus/parasiticus incidence in various substrates is shown in Table 3. Average incidence of flavus/parasiticus was 1.426 logic Table 1). Their presence was detected in 28 of 56... 

Delayed action cytotoxins that inhibit the synthesis of nucleic acids. They are obtained from various molds/fungi (Aspergillus flavus, Aspergillus parasiticus). They are colorless to pale-yellow crystalline materials melting above 450°F. The "B" toxins fluoresce blue in the presence of UV light while the "G" toxins fluoresce green. They are only slightly soluble in water, but are soluble in methanol, acetone, and chloroform. Aqueous solutions are "probably stable" and "probably tolerant" to chlorine at purification concentrations.

Studies by Lopez-Malo etaf. (1995,1997) showed the incorporation of vanillin ( 3— 7 mM) into fruit-based agars (apple, banana, mango, papaya and pineapple) inhibited the growth of Aspergillus flavus, A. niger, A. ochraceus and A. parasiticus for 2 months. Furthermore, synergistic effects... 

Afiatoxins were first isolated more than 40 years ago after the outbreak of disease and deaths in turkeys. These toxins are produced as secondary metabolites by the fungi Aspergillus flavus and Aspergillus parasiticus, at temperatures between 24 and 35°C and humidity exeeeding 7% (Williams et al, 2004). These fungi are known to infeet a variety of crops like peanuts, walnuts, pecans, pistachios, and com. 

Substituted coumarins (aflatoxins), from Aspergillus flavus and A. parasiticus. 

Aspergillus flavus and A. parasiticus produce the mycotoxin aflatoxin Bl. Aflatoxin B1 is a carcinogenic chemical that can cause liver cancer. Both ingestion and inhalation are proven exposure routes. Aflatoxin Bl has been found on contaminated grains, peanuts, and other foodstuffs. A. flavus and A. parasiticus are not commonly considered an indoor contaminant, unless the grains, peanuts, cereal-based animal food, or other foodstuffs are stored in an indoor environment.

Aflatoxin is a potentially carcinogenic compound produced by Aspergillus flavus and Aspergillus parasiticus which can invade peanuts, com, cottonseed and other commodities. Control and testing programs are in place in technologically advanced countries, and the concentrations of aflatoxin are usually quite low in edible peanuts however, the same may not be true in developing...
