Cyclopiazonic acid and aflaJoxins production by Aspergillus flavus
Thirty-four isolates of Aspergillus flavus obtained from the main Argentinian corn production area were tested for their ability to produce both cyclopiazonic acid (CPA) on corn and on liquid media and aflatoxins on corno Aflatoxins and CPA were quantified by comparison with standards. The last one was confirmed by mass spectrometry. AII but one of the isolates produced CPA on liquid medium in ...
متن کاملProduction of Aspergillic Acid by Surface Cultures of Aspergillus flavus.
It has been reported by White (1940), Rake, McKee, and Jones (1942), White and Hill (1943), Jones, Rake, and Hamre (1943), and Bush, Dickison, Ward, and Avery (1945) that the fungus Aspergillusflavus produces an antibiotic substance known as aspergillic acid. Aspergillusflavus is also known to produce other antibiotic substances such as flavacidin (McKee, Rake, and Houck, 1943; McKee and MacPhi...
متن کاملCyclopiazonic Acid Biosynthesis of Aspergillus flavus and Aspergillus oryzae
Cyclopiazonic acid (CPA) is an indole-tetramic acid neurotoxin produced by some of the same strains of A. flavus that produce aflatoxins and by some Aspergillus oryzae strains. Despite its discovery 40 years ago, few reviews of its toxicity and biosynthesis have been reported. This review examines what is currently known about the toxicity of CPA to animals and humans, both by itself or in comb...
متن کاملCase of keratitis caused by Aspergillus tamarii.
We report a case of Aspergillus tamarii keratitis. Ocular injury was known to be a predisposing factor. Topical natamycin and econazole treatment and subsequent systemic ketoconazole treatment proved effective. The isolate was identified by morphological characteristics and sequence analysis as A. tamarii, a member of Aspergillus section Flavi not hitherto reported from keratomycosis.
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 ...
