Aflatoxin B1 Mycotoxin Destruction using Allotropic Oxygen, O4, O5, O6 By Mary McPherson, Microbiologist Scientific Analytical Institute June
Aran is… Molecular Oxygen Plasma or what we call Polyatomic Oxygen Polymer - POP called Aran TM Oxygen commonly exists as an O 2 molecule. The Aranizer TM creates, through energy, higher allotropes of oxygen, O 4, O 5, O 6, O 8 … These oxygen molecules have oxidizing properties far greater than ozone and a much longer half-life. Thus we have a powerful oxidizer.
Reaction 5 molecules of aran to one molecule of mycotoxin will be enough aran to theoretically breakdown the Aflatoxin B1 Theoretical Formulation 5O 5 + C 17 H 12 O 6 CO 2 (vapor) + H 2 O (vapor) Basic theoretical formula
Tested Agent AJ-1 Aflatoxin B 1 Aspergillus flavus mycotoxin Chemical Formula C 17 H 12 O 6 Formula Weight The Aflatoxin B 1 compound was bought from Sigma Aldrich Company. It is a standard reagent grade mycotoxin, catalog # A6636 neat powder.
Aspergillus species capable of producing aflatoxins Species Mycotoxins produced AFB AFG CPA* Major sources Geographical distribution A. flavus + – – All kinds of foods Ubiquitous in warmer latitudes A. parasiticus + + – Peanuts Specific areas A. nomius + + – Bees USA, Thailand A. pseudotamarii + – + Soil Japan A. bombycis + + – Silkworm frass Japan, Indonesia A. ochraceoroseus + – – Soil Africa A. australis Soil, peanuts Southern hemisphere *AFB, B aflatoxins; AFG, G aflatoxins; CPA, cyclopiazonic acid IARC MONOGRAPHS VOLUME 82
Why Common Health Problem – listing was revised to known to be human carcinogens in the Sixth Annual Report on Carcinogens in National Toxicology Program, Department of Health and Human Services Liver Cancer Occurrence in foods cereals, oilseeds, spices and tree nuts, maize, groundnuts (peanuts), pistachios, brazils, chilies, black pepper, dried fruit and figs, milk, nonfat dry milk, cheese, yogurt, peanut butter, eggs, meat, and just about any other food substance that is grown in warm moist climates This is your liver on mycotoxin
Farm Related Benefits Environmental Farm Contaminant Storage Contaminant Field Practices Shipping commodities
Still on WHY Chemical Formula - C 17 H 12 O 6 important because this has benzene ring and bonds that are in many other compounds that the allotropic oxygen can breakdown such as solvents, formaldehyde, and other biological agents.
Aflatoxin B1 History Aflatoxins were first identified in England in 1960s the shorthand of its causative agent: A. fla.10,000 turkeys and ducks died within a few months - called Turkey X disease Cause - Aspergillus flavus contamination of peanut meal Previous to this: Khrushchev in 1939 was faced with horses dying on farms all over the western parts of the Ukraine. Khrushchev wrote, I cant believe that science is absolutely helpless here… We had won more than just a victory for our agriculture. It was a moral and political victory as well. But how many collective farm chairmen, cattle raisers, agronomists, animal husbandry specialists, and scientists had lost their heads as saboteurs before I stepped in and took charge of the situation. Korneev (1948) fed white mice with oats infested with Stachybotrys alternans strains According to Gajdusek (1953), cases of human stachybotryotoxicosis have been found mainly in regions where the equine disease has also been reported. Forgacs et al. (1958) studied the toxicity of 40 strains The Role of Stachybotrys in the Phenomenon Known as Sick Building Syndrome EEVA-LIISA HINTIKKA Finnish Institute of Occupational Health Uusimaa Regional Institute of Occupational Health Arinatie 3A, FIN-00370Helsinki, Finland
Glove Box The final setup is: an unknown portion of Aflatoxin B 1 placed in a clean (sterile) 250 mL Erlenmeyer flask. A 100 mL aliquot of distilled water was added to the Erlenmeyer flask. AJ-1 Aranizer Cup & Tubing
Equipment Data AJ-1 Aranizer output 2525 mg/hr Aran gas average molecular weight of O 6 previous similar models tested by Campbell and Associates Spectrophotometer 2401 Schimadzu UVProbe 190 nm – 900 nm peak analyses peaking below 190 nm - O 4 peaks at 151 nm PK Laboratory Analyzed the series of samples and blanks using HPLC
Sampling 2 - Blanks taken from the dilution water not treated 1 aliquot of dilution water was Aranized for comparison mL aliquots were taken from the original test matrix – labeled Start Point NOTE the Aflatoxin did not dissolve well– therefore the sampling was done while the sample was being stirred to ensure well mixed samples After 30 minutes 1 – 10 mL After another 30 minutes 1 – 10 mL sample was taken labeled 60 minutes After another 11 hours 1 – 10 mL sample was taken labeled 12 hours
