Table 4 The activity of XR and XDH of C. sorokiniana with different cofactors a

From: Induction of D-xylose uptake and expression of NAD(P)H-linked xylose reductase and NADP + -linked xylitol dehydrogenase in the oleaginous microalga Chlorella sorokiniana

  NADPH NADH NADP+ NAD+
XRb (U mg-1 protein) 0.021 0.004 - -
XDHc (U mg-1 protein) - - 0.026 ND
  1. aThe induced algal cells were washed with sterile distilled water and re-suspended in 8 mg DCW per mL in 50 mL minimal medium supplemented with 5 mM KNO3 and 40 mM D-xylose under light for 24 hours.
  2. bThe activity of XR was measured at pH 6.0 and 40°C.
  3. cThe activity of XDH was measured at pH 8.0 and 40°C.
  4. ND, Not detected.
