Correction to “Understanding the Role of pH Regulation and Neutralizing Agents in Organic Acid Production and Growth of Aspergillus oryzae”

Hartmann, L., Martin, M.C., Neumann, A., Holtmann, D. and Ochsenreither, K. 2026. Understanding the Role of pH Regulation and Neutralizing Agents in Organic Acid Production and Growth of Aspergillus oryzae. Biotechnology and Bioengineering, 123: 116–133. https://doi.org/10.1002/bit.70091.

In Equations (4) and (5), the index notation was incorrect:

Where it reads:

$$\text{OTR}=\frac{{\mathrm{p}}_{\text{gas}}{\mathrm{F}}_{\text{gas},\text{in}}}{\mathrm{R}{\mathrm{T}}_{\text{gas}}}\left({\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-\frac{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}}{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}}{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}\right)$$ (4)

$$\text{CTR}=\frac{{\mathrm{p}}_{\text{gas}}{\mathrm{F}}_{\text{gas},\text{in}}}{\mathrm{R}{\mathrm{T}}_{\text{gas}}}\left({\mathrm{y}}_{{\text{CO}}_2,\text{ex}}\frac{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}}{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}\right)$$ (5)

It should read:

$$\text{OTR}=\frac{{\mathrm{p}}_{\text{gas}}{\mathrm{F}}_{\text{gas},\text{in}}}{\mathrm{R}{\mathrm{T}}_{\text{gas}}}\left({\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-\frac{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}}{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}-{\mathrm{y}}_{{\text{CO}}_2,\text{off}}}{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}\right)$$ (4)

$$\text{CTR}=\frac{{\mathrm{p}}_{\text{gas}}{\mathrm{F}}_{\text{gas},\text{in}}}{\mathrm{R}{\mathrm{T}}_{\text{gas}}}\left({\mathrm{y}}_{{\text{CO}}_2,\text{off}}\frac{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{in}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}}{1-{\mathrm{y}}_{{\mathrm{O}}_2,\text{off}}-{\mathrm{y}}_{{\text{CO}}_2,\text{off}}}-{\mathrm{y}}_{{\text{CO}}_2,\text{in}}\right)$$ (5)

In the Discussion, the term “reduced hypoxia” should read “induced hypoxia”. The unit “nL” should read “L_n” (liters under normal conditions) throughout the manuscript.

We apologize for this error.
