Abstract The objective of this paper is to present a reliable yet convenient method of measuring simultaneously oxygen diffusion coefficients and solubilities in aqueous electrolyte solutions with a membrane-covered oxygen electrode. Measurements have been conducted in solutions of sodium chloride, potassium chloride, sodium sulfate, and magnesium sulfate over wide ranges of salt concentrations. The experimental results on oxygen diffusion coefficients and solubilities in test electrolyte solutions show an excellent accord with the literature data.

In a typical submerged aerobic fermentation with microbial pellets, the effective diffusivity of oxygen in the pellets is probably the most important, yet most difficult transport property to characterize experimentally. Its values directly indicate the efficiency or deficiency of oxygen to individual cells, and thus the biological activity of the microorganisms. In the past, it was not possible to assess reliably the effective diffusivity of oxygen in pellets due to several reasons. Firstly, most oxygen electrodes available were coarse, and hence not suitable for in situ measurements. Secondly, there was a lack of methods rigorous enough to characterize the structure of the microbial pellets. A state-of-the-art review of the literature relating to the feature subject is presented. Emphasis is laid upon development and evolution of the means for quantitative characterization of the effective diffusivity of oxygen in microbial pellets.
