Definition

solution saturation ratio that is the dissolved oxygen concentration in a liquid solution relative to the dissolved oxygen saturation concentration in that liquid solution

Explanatory Notes

The dissolved oxygen saturation concentration (and therefore the dissolved oxygen saturation ratio) is condition-dependent, varying with temperature, salinity (or ionic strength), total pressure, and the oxygen partial pressure in the gas phase in contact with the liquid. In bioprocessing practice, “100% DO” is commonly defined as equilibrium with air at approximately 21% O₂ (at the prevailing total pressure), rather than equilibrium with pure oxygen, unless otherwise specified.

Examples

• the dissolved oxygen saturation ratio of cell culture medium in a production bioreactor at 37 °C; the dissolved oxygen saturation ratio of a seed train culture during aeration control; the dissolved oxygen saturation ratio of medium equilibrated with air before inoculation;

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs for creating a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

DissolvedOxygenSaturationRatio(x) → SolutionSaturationRatio(x) ∧ ∃s∃l (Solution(s) ∧ qualityOf(x, s) ∧ LiquidAggregateState(l) ∧ hasQuality(s, l) ∧ ∀p(hasMagnitudeBasisInBearerPart(x,p) → (DioxygenMolecule(p) ∧ isMadeOfAtSomeTime(s,p))))

Semi-Formal Natural Language Axioms

if x is a ‘dissolved oxygen saturation ratio’ then x is a ‘solution saturation ratio’ that is the ‘quality of’ some ‘solution’ that ‘has quality’ some ‘liquid aggregate state’, and if x ‘has magnitude basis in bearer part’ some p, then p is a ‘dioxygen molecule’ of which that same ‘solution’ ‘is made of at some time’
