Abstract

Saccharomyces cerevisiae has been widely used in research to help understand eukaryotic cells, and their many functions.
Wine yeasts have not been used for many reasons, mainly only to study the properties they have that contribute to making wines.
This experiment grew both the lab strains and the wine strains in 15ºC and 30ºC.
- The environment was purposefully nitrogen-limited and anaerobic, regulated by a chemostat.
Growth temperature had a large affect on the growth or biomass of both of the strains.
The wine strain seemed to be better at forming biomass and the laboratory strain was better at fermenting under these conditions.
Analysis of the results was done by using DNA microarrays as well as metabalome analysis.
- This helped identify genes in each strain which were affected by the different temperatures.
- By doing this, genes could be identified which were different because of the different strains as well as the genes which were different because of the temperatures.
  - 1,007 temperature-dependent genes were found and 473 strain-dependent genes were found.
