Formation of Aflatoxin in Cheddar Cheese by Aspergillus flavus and Aspergillus parasiticus

Journal of Dairy Science, 1967
Abstract Three-month-old Cheddar cheeses were inoculated on one freshly cut surface with spore suspensions of Aspergillus flavus or Aspergillus parasiticus (toxigenic strains) and incubated at room temperature. Cheeses were sampled after 10 and 52 days of incubation and samples were examined by thin-layer chromatographic procedures for their ...

Loss of msnA, a Putative Stress Regulatory Gene, in Aspergillus parasiticus and Aspergillus flavus Increased Production of Conidia, Aflatoxins and Kojic Acid

Toxins, 2011
Production of the harmful carcinogenic aflatoxins by Aspergillus parasiticus and Aspergillus flavus has been postulated to be a mechanism to relieve oxidative stress. The msnA gene of A. parasiticus and A.

Effect of Halomethanes on Aflatoxin Induction in Cultures of Aspergillus parasiticus [PDF]

Microbiology, 1985
SUMMARY: The addition of tribromo-, tetrabromo- and chloromethanes to cultures of Aspergillus parasiticus strongly stimulated aflatoxin biosynthesis. The presence of phenobarbital in the cultures enhanced this effect. Following the addition of 14CCl4 to a culture, after 15 d incubation, 8·6% of the total radioactivity was recovered from the mycelium ...

Discrimination between aflatoxigenic and non-aflatoxigenic Aspergillus section Flavi strains from Egyptian peanuts using molecular and analytical techniques

, 2011
A wide range of Aspergillus section Flavi strains were isolated from Egyptian peanut samples. Eighteen of these strains were compared with two type strains (Aspergillus flavus SRRC G1907 and Aspergillus parasiticus 2747) for aflatoxin production based

Blasticidin A as an Inhibitor of Aflatoxin Production by Aspergillus parasiticus.

The Journal of Antibiotics, 2000
Blasticidin A, an antibiotic, showed strong inhibitory activity toward aflatoxin production by Aspergillus parasiticus. Its structure was characterized by NMR and chemical degradation experiments as 1, which is a tetramic acid derivative with a highly oxygenated long alkyl chain similar to aflastatin A (2).

Evaluation of Storage Conditions and Pre‐Treatment Methods to Mitigate Aflatoxin Contamination in Commonly Used Chinese Herbal Medicines

Phytochemicals in Food and Medicine, Volume 1, Issue 2, June 2026.
High temperature and humidity significantly promote aflatoxin contamination in herbal medicines. This research demonstrates that drying, vacuum packaging, and sulfur fumigation are effective strategies to minimize contamination and extend shelf life, whereas UV exposure proves ineffective for decontamination.
