Baker’s yeast

1998
When the subject of modern biotechnology is brought up, many people think first of pharmaceutical and medical products like interferon, human growth hormones and insulin, produced by genetically modified microorganisms. These products speak to people’s imagination: species originally not equipped with the genetic material to produce scarce and ...

Computer‐aided baker's yeast fermentations

Biotechnology and Bioengineering, 1977
AbstractThe economics of yeast production depend heavily upon the cellular yield coefficient on the carbon source and the volumetric productivity of the process. The application of an on‐line computer to maximize these two terms during the fermentation requires a continuous method of measuring cell density and growth rate.

Baker’s Yeast Production

1991
Bread doughs are fermented for very short periods of time with a range of 30 minutes to 4 hours. They are inoculated with 300 × 106 cells per gram and there is little or no yeast growth during the fermentation. In contrast, wine, beer, and distiller’s mashes are fermented for periods ranging from several days to several weeks. Inoculation levels are in

Thiamine Triphosphate in Bakers' Yeast

Nature, 1953
IN earlier work on cocarboxylase (thiamine diphosphate) as a phosphate carrier, an unknown spot was often found, not reported in the previous publication1, when extracts from liver were chromatographed in order to isolate thiamine diphosphate from other phosphate compounds. This unknown spot gave, like thiamine diphosphate, a blue fluorescence in ultra-

Intracellular pH of baker’s yeast

Folia Microbiologica, 1963
The distribution of bromophenol blue between the cell and the medium was used to calculate the intracellular pH of yeast.

Mutarotase in galactose-induced baker's yeast

Folia Microbiologica, 1974
Cell-free extracts of baker's yeast possess mutarotase activity only after induction of cells in the presence of galactose. The mutarotase activity appears 1 h after transfer to a galactose-containing medium and rises in synchrony with the utilization of galactose.

Baker’s Yeast Production

2000
Yeast production is an important industry in several fields: besides baker’s yeast, these are animal feed yeast, yeast for hydrolyzates used in biotechnology and the food industry, and in biotechnology as host organism for foreign genes. Thus there is a wide application area of models as presented in this chapter, which is structured as follows.

Transport of ethanol in baker’s yeast

Folia Microbiologica, 1985
Ethanol is transported into various strains of baker's yeast by simple diffusion (no effect of inhibitors and a linear concentration dependence of the initial rate of uptake and final distribution in cells). It distributes itself in 96.6 +/- 16.2% of intracellular water.

Spermidine synthesizing enzymes in baker's yeast

Biochemical and Biophysical Research Communications, 1971
Summary Baker's yeast (Saccharomyces cerevisiae) is a rich source of two enzymes responsible for the synthesis of spermidine: (i) S-adenosyl methionine decarboxylase, and (ii) spermidine synthase, which catalyzes the synthesis of spermidine from decarboxylated S-adenosyl methionine and putrescine.

The proteome of baker's yeast mitochondria

Mitochondrion, 2017
In the past decade mass spectrometry-based proteomics has greatly contributed to shaping our knowledge about Saccharomyces cerevisiae mitochondria, from the initial identification of novel essential components in purified protein complexes, to the actual characterization of the mitochondrial proteome, the specific analysis of mitochondrial ...
