The human pathogenic yeast Candida glabrata is the second most common Candida pathogen after Candida albicans, causing both bloodstream and mucosal infections. The centromere (CEN) DNA of C. glabrata (CgCEN), although structurally very similar to that of Saccharomyces cerevisiae, is not functional in S. cerevisiae. To further examine the structure of the C. glabrata inner kinetochore, we isolat...
Protein recovery under sonication treatment and autolysis, also protein hydrolysis progress during enzymatic hydrolysis (using trypsin and chymotrypsin) and autolysis (using endogenous enzymes) were investigated in Saccharomyces cerevisiae and Kluyveromyces marxianus. Crude protein content of dried yeast cells were 53.22% and 45.6% for S.cerevisiae and K.marxianus, respectively. After 96 hrs of...
Designing enriched probiotic supplements may have some advantages including protection of probiotic microorganism from oxidative destruction, improving enzyme activity of the gastrointestinal tract and probably increasing half-life of micronutrient. In this study Saccharomyces cerevisiae enriched with α-tocopherol produced as an accumulator and transporter of a lipid soluble vitamin for the fir...
Eukaryotic initiation factor 3 (eIF3) is a multisubunit complex that is required for binding of mRNA to 40 S ribosomal subunits, stabilization of ternary complex binding to 40 S subunits, and dissociation of 40 and 60 S subunits. These functions and the complex nature of eIF3 suggest multiple interactions with many components of the translational machinery. Recently, the subunits of mammalian a...
The synthesis of biotin, a vitamin required for many carboxylation reactions, is a variable trait in Saccharomyces cerevisiae. Many S. cerevisiae strains, including common laboratory strains, contain only a partial biotin synthesis pathway. We here report the identification of the first step necessary for the biotin synthesis pathway in S. cerevisiae. The biotin auxotroph strain S288c was able ...
There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...
background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
the aim of present study is investigating effect of treated lemon pulp by saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. in this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by saccharomyces cerevisiae yeast on protein recei...
Differences between the recombinant xylose-utilizing Saccharomyces cerevisiae strain TMB 3399 and the mutant strain TMB 3400, derived from TMB 3399 and displaying improved ability to utilize xylose, were investigated by using genome-wide expression analysis, physiological characterization, and biochemical assays. Samples for analysis were withdrawn from chemostat cultures. The characteristics o...
Co-evolution of transcriptional regulatory proteins and their sites of action has been often hypothesized but rarely demonstrated. Here we provide experimental evidence of such co-evolution in yeast silent chromatin, a finding that emerged from studies of hybrids formed between two closely related Saccharomyces species. A unidirectional silencing incompatibility between S. cerevisiae and S. bay...
