Fermentation profiles in the presence of different concentrations of acetic acid. CO2 production was determined from the weight loss during fermentation and expressed as percentage of initial weight of the total culture medium. a Acetic acid sensitive diploid strain Ethanol Red. b Acetic acid sensitive Ethanol Red haploid segregant ER18. c Acetic acid-tolerant diploid strain JT22689. d Acetic acid-tolerant JT22689 haploid segregant 16D. Strains were inoculated in YPD medium with 2 % glucose at pH 4 and various concentrations of acetic acid: 0 % (), 0.4 % (v/v) (), 0.5 % (v/v) (), 0.6 % (v/v) (), 0.7 % (v/v) (), 0.8 % (v/v) (), 0.9 % (v/v) (), 1.0 % (v/v) (). Data points are the average of duplicate measurements; error bars represent the maximum deviation of the average
