biofuel production | the enzyme might be useful for production biofuels from D-xylose. Chlorella sorokiniana can uptake D-xylose only by an inducible D-xylose transportation system in a light-dependent manner after induction with D-glucose. Xylose reductase (XDH) then converts 50 to 60% of the consumed D-xylose to xylitol, which is subsequently converted to D-xylulose | Chlorella sorokiniana |
