Mechanisms regulating the transport of acetic acid in Saccharomyces cerevisiae
Article Abstract:
The mechanism of transport of acetic acid and other monocarboxylic acids in cells of Saccharomyces cerevisiae depends on the carbon source used for growth. Cells grown in acetic acid or ethanol as the carbon and energy source transport acetic, propionic and formic acids using a monocarboxylate/proton symport. Cells grown in lactic acid use two distinct symports for the transport of monocarboxylic acids. One is the low affinity acetate/proton symport and the other is the high affinity symport that transports lactate, pyruvate and propionate.

Effects of ethanol and other alkanols on transport of acetic acid in Saccharomyces cerevisiae
Article Abstract:
The hypothesis that the food and beverage yeast Zygosaccharomyces bailii can control the concentration of acetic acid that enters ethanol-, acetic acid- and glucose-grown cells to achieve compatibility with the metabolic flux is tested in the yeast Saccharomyces cerevisiae. Specifically, the study analyzed how acetic acid uptake in S. cerevisiae IGC 4072 grown on different carbon sources is affected by ethanol and other alkanols. The findings are discussed.

Saccharomyces cerevisiae commits to a programmed cell death process in response to acetic acid
Article Abstract:
Research demonstrates that an apoptotic phenotype in Saccharomyces cerevisiae is inducible via oxidative stress. Results show that cells exposed to 20-200 millimolar acetic acid for 200 minutes at pH 3.0 experience cell dealth.
