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
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
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.

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.

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.

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.
