Project description:Phenylethanol-resistant S. cerevisiae mutants were obtained by using evolutionary engineering strategy. Briefly, a chemically mutagenized culture was used as the initial population for the selection procedure. Gradually increasing levels of phenylethanol stress was applied through 56 successive batch cultivations. Individual mutants were selected from the final population. The mutant with the highest phenylethanol resistance could resist up to 3 g/L phenylethanol concentrations. Whole-genome transcriptomic analyses of the phenylethanol-resistant mutant strain and the reference strain were performed by using DNA microarray technology, in the absence of phenylethanol stress.

Whole-genome transcriptomic analyses of the phenylethanol-resistant mutant strain and the reference strain were performed by using DNA microarray technology, in the absence of phenylethanol stress. Agilent yeast DNA microarray systems were used for whole-genome transcriptomic analyses of the reference strain and the selected phenylethanol-resistant mutant. Three replicates of each culture were grown in 100 mL yeast minimal medium using 500 mL flasks, at 30°C and 150 rpm. Cells at logarithmic phase of growth (~1.0 OD600) were used for total RNA isolation.
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.
