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

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

	NADPH	NADH	NADP⁺	NAD⁺
XR^b (U mg^-1 protein)	0.021	0.004	-	-
XDH^c (U mg^-1 protein)	-	-	0.026	ND

^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.
^bThe activity of XR was measured at pH 6.0 and 40°C.
^cThe activity of XDH was measured at pH 8.0 and 40°C.
ND, Not detected.
