From: Dynamic response of Aspergillus niger to single pulses of glucose with high and low concentrations
Extracellular glucose concentration profiles in the first 10 min after the glucose pulses. a High glucose concentration (3.00 g glucose addition via a syringe containing concentrated glucose concentration); b low glucose concentration (0.34 g glucose); c phasing scheme of the glucose pulse experiments (SS: steady state; I: glucose-rich phase and II: glucose-depletion phase for the low glucose concentration pulse experiment)
