Studies on Yeast Metabolism
Direct measurement ofthe metabolic changes in the intracellular carbohydrate ofyeast has usually been restricted to the determination oftotal hydrolysable carbohydrate, that is to say, ofreducing power after acid hydrolysis of a cell suspension. The work of Pickett & Clifton (1943), or of Fales & Baumberger (1948), exemplifies this technique applied respectively to the aerobic and anaerobic met...
متن کاملInfluence of Different Yeast Strains on Metabolism of Tryptophan and Indole-3-Acetic Acid During Fermentation
The effect of supplementation of Riesling (Vitis vinifera L.) must with ammonium sulphate (AS) on tryptophan (Trp) and indole-3-acetic acid (IAA) metabolism during alcoholic fermentation with four commercial yeast strains (Uvaferm CEG, Lalvin Cross Evolution, Anchor VIN 13 and Anchor exotic SPH) were examined. AS addition reduced Trp uptake by yeasts from 1% to 15%. Wines produced by Anchor VIN...
متن کاملThe metabolism of yeast nucleic acid in the rat.
Recent studies on the fate of labeled dietary purines in the rat have shown t,hat dietary adenine is a precursor of t,he adenine and of the guanine of tissue nucleic acids (l), but that guanine (2), hypoxanthine (3), and xanthine (3) are not utilized for nucleic acid synthesis. Similar experiments have shown that the pyrimidines, uracil, thymine (2), and cytosine (4) are not incorporated into t...
متن کاملThe Structure of Yeast Nucleic Acid
The tetranucleotide theory of the structure of yeast nucleic acid was first enunciated by the writer1 and was subsequently conclusively demonstrated by the experimental evidence furnished by Levene and Jacobs,2 ‘and by Levene and La Forge.3 The facts on which the theory was based were: first, the isolation of four nucleosides; second, the isolation of simple pyrimidine nucleotides. These were o...
متن کاملEffect of low-temperature fermentation on yeast nitrogen metabolism
The aim of this study was to analyse the influence of low-temperature wine fermentation on nitrogen consumption and nitrogen regulation. Synthetic grape must was fermented at 25 and 13 C. Lowtemperature decreased both the fermentation and the growth rates. Yeast cells growing at low-temperature consumed less nitrogen than at 25 C. Specifically, cells at 13 C consumed less ammonium and glutamine...
