Transcriptomic analysis of sulfur dioxide stress-resistant Saccharomyces cerevisiae strain obtained by evolutionary engineering

Project description:In this study, we have developed a highly SO2-stress-resistant yeast (Saccharomyces cerevisiae) strain [F3] using evolutionary engineering, by successive batch selection at gradually increased SO2 levels. The evolved F3 strain was resistant to 1.0 mM SO2 stress, which was strongly inhibitory to the reference strain. Whole-transcriptomic analysis of F3 was performed with respect to its reference strain to determine differences in gene expression levels between the two strains. Saccharomyces cerevisiae

Transcriptomic analysis of a caffeine-resistant Saccharomyces cerevisiae strain obtained by evolutionary engineering

Project description:A caffeine-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation at gradually increasing caffeine levels. The mutant strain Caf905-2 was selected at a caffeine concentration where its reference strain could not grow at all. Whole-genome transcriptomic analysis of Caf905-2 was performed with respect to its reference strain.

Transcriptomic analysis of a propolis-resistant Saccharomyces cerevisiae strain obtained by evolutionary engineering

Project description:A propolis-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation under gradually increasing propolis levels. The mutant strain FD 11 was selected at a propolis concentration that the reference strain could not grow at all. Whole-genome transcriptomic analysis of FD11 was performed with respect to its reference strain to determine differences in gene expression levels between the two strains. Saccharomyces cerevisiae

Transcriptomic analysis of an iron-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:Iron-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering selection strategy. The mutant obtained “M8FE” is much more resistant to iron stress than the reference strain which was used to select this mutant. Mutant can resist up to 35mM Iron* stress whereas the reference strain cannot. Whole-genome microarray analysis might be promising to identify the iron resistance mechanisms and stress response upon high levels of iron in the yeast cells. Iron-resistant mutant is also cross resistant to Cobalt, Chromium and Nickel but sensitive to Zinc. * refers to [NH4]2[Fe][SO4]2 and FeCl2.

Transcriptomic analysis of silver-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:Silver-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering method. Briefly, genetic diversity in reference strain, CEN.PK.113-7D, was increased by ethyl methane sulfonate (EMS)-mutagenesis. The mutant population was passaged several times in gradually increasing silver stress. Several mutant individuals were selected from the final population. Among selected mutant individuals, one of them was much more resistant to silver stress than the reference strain, called as 2E. Whole-genome transcriptomic analysis was performed to identify the silver resistance mechanisms in the silver-resistant mutant strain.

Transcriptomic analysis of two ethanol-tolerant Saccharomyces cerevisiae clones obtained by evolutionary engineering

Project description:Evolutionary engineering strategy was used for selection of ethanol-tolerant Saccharomyces cerevisiae clones under gradually increasing ethanol stress levels. Clones B2 and B8 were selected based on their higher ethanol-tolerance and higher ethanol production levels. Whole genome microarray analysis was used for identifying the gene expression levels of these two evolved clones compared to the reference strain. Two evolved ethanol-tolerant strains B2 and B8, which were selected by evolutionary engineering under gradually increasing ethanol stress, were used for whole genome transcriptomic analysis in comparison with the reference strain. Cells were grown in yeast minimal media until they reach a final OD600 of 1. Following total RNA isolation, gene expression levels were analyzed using One-color microarray-based gene expression analysis (Agilent Technologies). Experiments were done in triplicates.

Transcriptomic analysis of a nickel-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:Nickel-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering. The reference strain which was used to select this nickel-resistant mutant could not grow even at 0.5 mM NiCl2 whereas this mutant was shown to be resistant upto 5.3 mM NiCl2 concentration. Whole-genome microarray analysis might be promising to identify the nickel resistance mechanisms in the yeast cells. The reference Saccharomyces cerevisiae strain and the nickel-resistant mutant were grown in minimal medium to an Optical Density (OD600) of 1.00 which correspond to the logarithmic growth phase of the yeast cells. Cultures were harvested and whole RNA isolation was carried out. The experiment was repeated three times.

Transcriptomic analysis of a NaCl-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:NaCl-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering. EMS mutagenized culture was used as the initial population for the selection procedure. Gradually increasing levels of NaCl stress was applied through 40 successive batch cultivations. The reference strain could not grow even at 0.85 M NaCl whereas this mutant was shown to be resistant up to 1.45 M NaCl concentration. Whole-genome microarray analysis was used to identify the NaCl resistance mechanisms by comparing NaCl-resistant mutant strain and the reference strain in the absence of NaCl stress.
