From: H2-driven xylitol production in Cupriavidus necator H16
H2-driven production of xylitol by C. necator △phaCAB at different d-xylose concentrations. The reaction mixtures were composed of 13, 34, 66, and 114 g/L of d-xylose in 100 mM sodium phosphate buffer (pH 7.0) and cells at OD600 of 13–15. The headspace contained 100% H2. The average from three bioconversions is shown. The standard deviations were below 1.1 g/L. The percentages represent the final conversion yields, calculated by dividing the xylitol concentration measured at the final time point by the xylose concentration at the start of the experiment
