Figure 4From: Overexpression of the Aspergillus niger GatA transporter leads to preferential use of D-galacturonic acid over D-xyloseCarbon consumed (a) and produced (b), expressed in Cmoles, for control strain (NW185 PYR A+strain) and transformant JS013 after 72Â h of growth on SCH medium. Samples taken from direct cultures, D-xylose in the mixed substrate medium serves as an inducer of the xlnD promoter. Totals represent 0.1 Cmoles.Back to article page
