Time course of macroscopic yields during A. niger idiophase.

  1. Citric acid (Yp/s), CO2 (Yco2/s) and Biomass (Yx/s) substrate yields. Values from Röhr et al. (1987).
  2. Polyol (Ypolyol/s) and Oxygen (Yo2/s) substrate yields. The substrate-polyol yields were determined by carbon balance among the cellular input (glucose) and outputs (citric acid, biomass and CO2). The negative values are indicative of net polyol consumption. The oxygen-substate yields was calculated by reductance grade balance among the all compounds interchanged between the cell and the medium. In all these calculations an average polyol composition [CH2.54O]3.72 was assumed.
