WebThe second equation for OTR max assumes that the concentration of O 2 in the liquid has been completely depleted (i.e. O 2 limited) and is dependent on the O solubility (𝐿𝑂 2) and the O 2 partial pressure in the gas phase (𝑝𝑂 2). The 𝐿𝑂 of H 2 O is approximately 1.18 mmol L-1 bar-1 at 30°C (decreasing with temperature) Webcharacterisation. By taking into account the oxygen transfer rate (OTR, Equation 1) and the OUR of the microorganisms (Equation 2 and 3), the oxygen gas balance for the liquid phase results as shown in Equations 4 and 5. (1) (2) The calculation of the OUR is normally based on the viable cell counts. Here, the whole cell population is
