Transcription profiling of Saccharomyces response to lactic acid in anaerobic chemostat cultures

ABSTRACT: Raw expression values (CHP data) for transcriptional profiling of the response of Saccharomyces cerevisiae to challenges with lactic acid at pH 3 and pH 5. Experiment Overall Design: The laboratory reference strain CEN.PK 113-7D (MATa) was grown at 30 °C in 1.5-L chemostat fermentors (Applikon, Schiedam, The Netherlands) with a working volume of 1-L using an electronic level sensor to maintain a constant volume. All cultures, including the reference, were fed with minimal medium as described by Verduyn et al. (1992) with 25 g L-1 glucose as the limiting nutrient and 0.15 ml L-1 silicone antifoam (BDH, Poole, England) to prevent excessive foaming. The dilution rate was set to 0.10 h-1 and the pH was controlled at 5.0 with the automatic addition (ADI 1031 bio controller, Applikon) of 2 M
