GLBRCY128 can anaerobically ferment xylose from ACSH.

<p>A diagram summarizing the engineering and evolution of the YB-210 strain into the evolved Y128 strain is provided in (<b>A</b>). Fermentation kinetic profiles of the Y127 (<b>B</b>) and Y128 (<b>C</b>) strains cultured in bioreactors containing ACSH and sparged with nitrogen from biological duplicates are shown. Average concentrations and standard deviations of indicated components were quantified from media samples at times from initial inoculation. Vertical colored bars indicate time points at which samples were taken for metabolomic analysis described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107499#pone-0107499-g007" target="_blank">Fig. 7A–D</a>.
