Fig. 9From: Dynamic response of Aspergillus niger to single pulses of glucose with high and low concentrationsa (NAD+/NADH)/(\({\text{NAD}}^{+}_{0}\)/NADH0) ratio profiles after the glucose pulses; b Asp/Mal ratio’s in both glucose pulse experiments. Vertical hashed lines represent the start of the glucose pulse. The steady-state level is represented as red horizontal lineBack to article page
