The Impact of Malolactic Fermentation Conducted by Oenococcus oeni on Brettanomyces bruxellensis Growth and Volatile Phenol Production

Creator:: Lauderdale, Adam D.
Abstract:: Wine is particularly vulnerable to infection by Brettanomyces bruxellensis during or shortly after malolactic fermentation (MLF). While different methods and techniques enable winemakers to prevent wine spoilage due to this organism, no single intervention is universally sufficient. Moreover application of sulfur dioxide, the most commonly used of these methods, is...

The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

Creator:: Valsta, Liisa M.
Abstract:: In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

Two Studies Addressing Practical Needs of Wheat Farmers, Processors, and Breeders : Changes in Falling Number and Alpha-amylase During Grain Storage, and Improved Predictions of Wheat-flour Dough Properties

Creator:: Adams, Mike R.
Abstract:: Wheat (Triticum aestivum) is a globally traded staple food crop. The diverse and pleasing nature of wheat-derived products is a result of the complex interactions of the polymeric components from the wheat endosperm. Changes in the functionality of these polymeric components, as a result of changes in growing conditions or...

Partial purification of cathepsins from salmon muscle

Creator:: Ting, Chao-Yun
Abstract:: Cathepsins are intracellular proteinases that hydrolyze the peptide bonds of proteins. These enzyme have been implicated in the tenderization of aging beef, with the deterioration of radiation-stabilized meats on storage, and in the spoilage of fish prior to processing. Hence, the cathepsins of edible muscles are of concern to the...

Effect of various parameters on in vivo Aflatoxin B₁ binding to rainbow trout (Salmo gairdneri) liver DNA

Creator:: Whitham, Mark
Abstract:: Aflatoxin B₁ (AFB₁,) is a potent liver carcinogen to a number of animal species including rainbow trout (Salmo gairdneri). Microsomal activation is required for the in vitro conversion of AFB, to a reactive metabolite, thought to be the AFB₁,-2,3-oxide, which will bind nucleic acids, produce toxicity, and cause mutagenesis. Nucleic...

Dietary protein and aflatoxin B₁ metabolism in rainbow trout (Salmo gairdneri)

Creator:: Stott, William T.
Abstract:: Dietary protein intake has been observed to influence the induction of cancer in animals exposed to carcinogens, presumably by affecting the activities of enzyme systems which metabolize them. One such carcinogen is aflatoxin B₁ (AFB₁) a mold metabolite and frequent contaminant of foodstuffs. Variations in the levels of dietary proteins...

Mechanisms of action by some inhibitors of aflatoxin B₁ carcinogenesis in rainbow trout

Creator:: Goeger, Douglas Eugene
Abstract:: Indole-3-carbinol (I3C) and butylated hydroxyanisole (BHA), anti-carcinogens present in the human diet, were tested for their in vivo and in vitro effect on aflatoxin B₁. (AFB₁) metabolism, and DNA adduct formation in the rainbow trout. Dietary BHA at either 0.3 or 0.03% had no effect on the hepatic tumor incidence...

B-Naphthoflavone induction and its effect on hepatic phospholipid metabolism in rainbow trout (Salmo gairdneri)

Creator:: Harris, Marcia Elaine
Abstract:: The induction of drug-metabolizing enzymes is a complex biochemical process manifested not only by increases in various cytochrome P-450 isozymes and related activities, but also by alterations in endoplasmic reticulum membranes. Little work has been done to examine how cytochrome P-450 inducing agents influence other cellular processes, such as phospholipid...

Nutritional and Genetic Aspects of Sulfite Excretion During Fermentation by Wine Strains of Saccharomyces cerevisiae

Creator:: Alessandri, María P.
Abstract:: Reductive sulfate assimilation, the biological process by which sulfur-containing amino acids and key derivatives are synthesized from sulfate, is broadly shared among bacteria, fungi, and plants. It is the major, if not sole source of methionine and cysteine for Saccharomyces cerevisiae during wine fermentation. Two obligate intermediates formed in the...
