Synthesis of aflatoxins by the non-growing mycelia of Aspergillus parasiticus and the effect of inhibitors.
A chemically defined medium giving high yields of aflatoxins has been reported from this laboratory (Reddy, Viswanathan & Venkitasubramanian, 1971). Many workers have studied the incorporation of [ 1J4C]acetate into aflatoxins (Adye & Mateles, I 964; Donkersloot, Hsieh & Mateles, 1968; Detroy & Hesseltine, 1969; Hsieh & Mateles, 1970, 1971). Labelled acetate is efficiently incorporated into afl...
متن کاملInfluence of temperature cycling on the production of aflatoxins B1 and G1 by Aspergillus parasiticus.
The effect of temperature cycling on the relative productions of aflatoxins B1 and G1 by Aspergillus parasiticus NRRL 2999 was studied. The cycling of temperature between 33 and 15 degrees C favored aflatoxin B1 accumulation, whereas cycling between 35 and 15 degrees C favored aflatoxin G1 production. Cultures subjected to temperature cycling between 33 and 25 degrees C at various time interval...
متن کاملSimultaneous quantitation of Aspergillus flavus/A. parasiticus and aflatoxins in peanuts.
A method was developed for simultaneous quantitation of Aspergillus flavus/A. parasiticus and aflatoxins in peanuts. Peanut samples were ground with an equal weight of water in a vertical cutter mixer to produce a slurry. Separate subsamples were taken for dilution-plating to determine total colony forming units (CFU)/g of A. flavus/A. parasiticus and for liquid chromatographic analysis to dete...
متن کاملEffect of Propolis on Growth, Aflatoxins Production and Lipid Metabolism in Aspergillus Parasiticus Spear
The mechanism of antifungal activities of propolis (Bee glue) was investigated for the growth, aflatoxins production, and lipids (total lipids, neutral lipids, phospholipids, and fatty acids) metabolism of Aspergillus parasiticus. The results of the present study indicated that propolis caused significant decrease in conidial production and conidial germination as well as mycelial growth (both ...
متن کاملParasitical: A New Metabolite from Aspergillus parasiticus
Parasiticol, a metabolite structurally related to the aflatoxins, has been isolated and characterized. The compound is elaborated by several strains of the Aspergillus jiaDus series previously shown to be aflatoxin producers. The metabolite was separated and purified by chromatography Oll three columns (silicic acid, silica gel, and alumiua) followed by recrystallization from chlorofom,-bexane....
