H2-driven production of xylitol by C. necator △phaCAB on different oxygen concentrations. The reaction mixtures contained initially ⁓ 30 g/L of d-xylose in 100 mM sodium phosphate buffer (pH 7.0) with cells at OD600 of 16. The used gas mixtures consisted of 0% O2 and 100% H2, 1% O2, 2% N2, and 97% H2 or 4% O2, 13% N2, and 83% H2. The average from three bioconversions is shown with the standard deviation. 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
