Conversion of xylose into xylonate using whole cells of G. oxydans 621H and G. oxydans ∆GOX1068∆GOX0854 prepared from the mineral salts medium with 2 g L⁻¹ glycerol as the sole carbon source. (Black square) xylose consumption of G. oxydans 621H, (red circle) xylose consumption of G. oxydans ∆GOX1068∆GOX0854, (blue triangle) xylonate formation of G. oxydans 621H, (pink inverted triangle) xylonate formation of G. oxydans ∆GOX1068∆GOX0854. The error bars represent the standard deviations of three independent experiments
