Figure 2. Effect of lipid factors on the viability of S. cerevisiae EC1118 cells during alcoholic fermentation.

The synthetic medium contained 142 mg/L assimilable nitrogen (SM142) and 5% lipid factor (LF5%), with or without additional oleic acid or ergosterol (content as in LF100%). Viability was measured by flow cytometry after propidium iodide staining. The graphs are the result of smoothing of measurements series (at least 3 repetitions) using the software R. Smoothing obtained is framed by a confidence interval calculated at 95%.
