The effects and interactions of temperature (5, 19, 28, 37°C), initial pH (6.0 and 7.5), atmosphere (aerobic and anaerobic), sodium chloride content (0.5 and 4.5%), and sodium nitrite concentration (0, 50, 100, 200, 1000 μg/ml) on the growth of Lis

Earlier work characterizing the effects of glucose analogs on growth and aflatoxin production by Aspergillus parasiticus was expanded by assessing the effects of β-methylglucose (βMG), 3-0-methylglucose (3MG) and thioglucose (TG). As sole carbon so

A sequential technique involving the transfer of mycelia from a peptone-based, aflatoxinnonsupporting medium to a glucose-based, aflatoxin-supporting medium was used to study possible relationships between tricarboxylic acid cycle activity and aflato

The ability of a wide variety of carbon sources to induce and support aflatoxin synthesis by Aspergillus parasiticus was examined using mycelia pregrown in a peptone-mineral salts medium that does not support aflatoxin synthesis. Sugars and derivativ

Studies were performed to characterize further Aspergillus parasiticus BCR1, a caffeine-resistant mutant of A. parasiticus NRRL 2999, particularly in regard to its caffeine-dependent production of aflatoxins. The enhanced synthesis of aflatoxins by c

The effects of 2-deoxyglucose (2-DOG), alpha-methylglucoside (alpha-MG), and glucosamine (GA) on aflatoxin production by Aspergillus parasiticus were studied using conidia-initiated and replacement cultures. In conidia-initiated, 2-DOG, alpha-MG, and

Listeria methods research at the U.S. Department of Agriculture, Eastern Regional Research Center, has concentrated on 2 areas during the past year. The first was development of techniques for assessing isolation methods for their ability to detect s

At 5 microM, miconazole prevented the growth of Aspergillus parasiticus Speare in a number of media. Sensitivity to miconazole was increased approximately 10-fold in a medium containing glycerol. At sub-inhibitory concentrations, miconazole stimulate

SUMMARY: The effects of thioglycerol on growth and aflatoxin production by Aspergillus parasiticus were studied using conidia-initiated cultures and pregrown mycelia. Thioglycerol inhibited both growth and aflatoxin synthesis, with toxin formation be

Moxalactam, nalidixic acid and bacitracin were found to be an effective combination of selective agents that permitted growth of Listeria while suppressing most foodborne genera. These selective agents were used to formulate Modified Vogel Johnson Ag
