The fate of ochratoxin A (OA) was studied in goats given a single oral dose of 3H-OA (0.5 mg/kg). More than 90% of the radioactivity was found to be excreted in 7 days and the majority (53%) was found in feces. Thirty-eight percent, 6% and 2.26% of the activity was found in urine, milk and serum, respectively. The radioactivity in the liver and kidney 6(More)
The fate of ochratoxin A in brewing was investigated by adding (3H)ochratoxin A to the raw materials at 1- and 10-mug/g levels during mashing in a conventional microbrewing process. The results indicated that large portions (28 to 39%) of the added toxin were recovered in spent grains, with less recovery in the yeast (8 to 20%) and beer (14 to 18%). About(More)
Leaf and root tissues of clubroot-resistant cabbage line 8–41 and cultivar Badger Shipper, and clubroot-susceptible cultivars Penn State Ballhead and Golden Acre were analysed for free amino acid content. There was no relationship between total free amino acid content and susceptibility to the disease. Alanine and asparagine contents were higher in the leaf(More)
Factors affecting the production of [14C]patulin from [1-14C]acetate by replacement cultures of Penicillium patulum have been investigated. Incorporation of [1-14C]acetate into patulin reached a maximum with 6- to 8-day-old cultures incubated at 28 degrees C for 8 h in a replacement medium containing 0.1 M glucose, inorganic salts, and undiluted(More)
