Fermentation profiles of <i>S. cerevisiae</i> and <i>Z. bailii</i> cultured with and without acetic acid.

<p>The graphs show data until all the carbon sources had been utilized. <b>A</b>. <i>S. cerevisiae</i> cultured in minimal medium. <b>B... </b><i>S. cerevisiae</i> cultured in minimal medium with 9 g L⁻¹ acetic acid. <b>C... </b><i>Z. bailii</i> cultured in minimal medium. <b>D... </b><i>Z. bailii</i> cultured in minimal medium with 24 g L⁻¹ acetic acid. The graphs represent the mean of n≥3 biological replicates with error bars indicating standard deviation. For the sake of clarity, error bars are omitted from the insert in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0073936#pone-0073936-g001" target="_blank">figure 1B</a>.
