Summary The equilibrium oxygen concentration (C0) was determined in a complex fermentation media containing sucrose, lysine, molasses, corn steep liquor, antifoam agents and biomass. In simple systems, with all the components being dissolved, C0 represents the oxygen solubility and linearly decreases with increasing solute concentrations. In complex solutions with multi-phase structure an increase in C0 can be detected. It suggests that C0 consists of two components — one being oxygen solubility, the other being determined by the amount of oxygen adsorbed on the interphase and bound by macromolecules. The presence of biomass leads to a decrease in C0.
