Ethanol Bio-Production from Ricotta Cheese Whey by Several Strains of the Yeast Kluyveromyces
Ricotta Cheese Several Strains
2016/6/2
Studies describing the ethanol bio-production from ricotta cheese whey still are few and this limits the development of an industrial bioprocess. The aim of this study was to compare the ethanol produ...
Physiological state of reused brewing yeast
flavour compounds glycogen serial repitching trehalose yeast
2014/2/24
In brewing, yeast may be reused many times. A number of yeast repitchings differs significantly among the breweries. Adjusting the number of times a strain may be serially repitched is of great import...
Yeast PHO Genes: An Excellent Model for Elucidation of Chromatin-Remodelling Mechanisms
transcriptional regulation chromatin remodelling yeast PHO genes
2010/12/21
Nucleosomes, the basic units of chromatin structure, repress transcription by restricting
access of transcription factors to promoter cis-regulatory elements. It has recently become
clearly evident ...
Production of Carotenoid-/Ergosterol-Supplemented Biomass by Red Yeast Rhodotorula glutinis Grown Under External Stress
Rhodotorula glutinis carotenoids β-carotene ergosterol exogenous stress
2010/8/11
The aim of this study is to compare the production of biomass enriched with carotenoids and ergosterol by yeast strain Rhodotorula glutinis CCY 20-2-26 grown under optimal growth conditions and in the...
The Effect of ATP Sulphurylase on the Prooxidant Properties of Selenate in Yeast Schizosaccharomyces pombe
ATP sulphurylase Schizosaccharomyces pombe selenate
2009/8/10
Selenium is an essential microelement in human and animal nutrition, whose intake can be in inorganic (e.g. selenite, selenate) or organic form (e.g. selenomethionine). The prooxidant effect of inorga...
Pyruvate Decarboxylase Activity Assay in situ of Different Industrial Yeast Strains
enzymatic activity in situ pyruvate decarboxylase yeasts
2009/6/24
Cytoplasmic pyruvate decarboxylase (PDC, EC 4.1.1.1) is one of the key enzymes of yeast fermentative metabolism. PDC is the first enzyme which, under anaerobic conditions, leads to decarboxylation of ...
Kefiran Production by Lactobacillus kefiranofaciens under the Culture Conditions Established by Mimicking the Existence and Activities of Yeast in Kefir Grains
kefiran polysaccharide Lactobacillus kefiranofaciens lactic acid bacteria
2009/6/18
Kefiran production by Lactobacillus kefiranofaciens alone under the culture conditions established by mimicking the presence and activities of yeast cells in kefir grains was investigated. When the pH...
Electrochemical Measurement of Yeast Cell Density and Vitality Using 2,3,5-Trimethyl-1,4-benzoquinone and Effect of Ethanol on the Metabolism of Quinone by Yeast Cells
yeast density vitality quinone
2009/6/17
An electrochemical measurement of yeast cell density and vitality was developed using 2,3,5-trimethyl-1,4-benzoquinone. 2,3,5-Trimethyl-1,4-benzoquinone was reduced most effectively to the correspondi...
The Yeast Flora Occuring in the Trachea of Broiler Chicken

2009/3/23
The occurrence of bacteria as natural occupants of the intestinal flora of poultry is well documented. The incidence and composition of the yeast microflora, however, have received little attention. A...
Biochemical Studies on the Production of Acetic Acid by the Yeast Dekkera anomala
acetic acid production acetyl-CoA synthetase Dekkera anomala
2009/3/23
Cells of Dekkera anomala IGC 5153 grown in concentrations of glucose higher than 2 % (w/v) were able to produce high amounts of acetic acid, while in lower sugar concentrations the presence of the aci...
Heterochromatin-like structure at yeast telomeres is involved in the regulation of several important biological processes. Telomeres facilitate end replication, stabilize chromosomes and display many ...
