CONTAMINATION OF CEREALS WITH AFLATOXINS, METABOLITES OF FUNGI Aspergillus flavus
In stored cereals besides other microorganisms, Aspergillus flavus fungi, well known aflatoxin producers, can also be found. When these feedingstuffs, as main material for feed production, are very contaminated with fungi and mycotoxins, they induce different health disturbances both in animals and humans. However, the presence of fungi is not a proof of mycotoxins contamination because thay ar...
متن کاملIdentification and characterization of Aspergillus flavus and aflatoxins
Aspergillus flavus is the main producer of the well known carcinogenic aflatoxins. The presence of this fungus and aflatoxins is of huge concern in terms of food safety. The identification of A. flavus is not straightforward due to similarities with closely related species (e.g. A. parasiticus and A. nomius). Also, from the biochemical point of view the closely-related species are able to produ...
متن کاملAspergillic acid; an antibiotic substance produced by Aspergillus flavus.
The discovery by White (1) in 1940 that a strain of Aspergillus Jlavus, growing in surface culture on a tryptone-salt medium, produced a highly bactericidal filtrate from which White and Hill in 1943 (2) were able to isolate the active material in crystalline form added another member to the increasing group of chemically and biologically interesting antibiotic compounds. Because the mode of is...
متن کاملNitrification by Aspergillus flavus.
Marshall, K. C. (Cornell University, Ithaca, N. Y.) and M. Alexander. Nitrification by Aspergillus flavus. J. Bacteriol. 83:572-578. 1962.-Aspergillus flavus has been shown to produce bound hydroxylamine, nitrite, and nitrate when grown in peptone, amino acid, or buffered ammonium media. Free hydroxylamine was not detected in these cultures, but it was found in an unbuffered ammonium medium in ...
متن کاملProduction of aflatoxins B1 and G1 by Aspergillus flavus in a semisynthetic medium.
Isolates of Aspergillus flavus produced 0.2 to 63 mg of aflatoxins B(1) and G(1) per 100 ml in a nutrient solution consisting of 20% sucrose and 2% yeast extract. Various factors influencing the fermentation were studied. The maximal amount of toxin was produced by ATCC culture 15548 in 1-liter flasks containing 100 ml of medium incubated as stationary cultures for 6 days at 25 C.
