Correlation of cell volume fractions with cell concentrations in fermentation media.
Cell volume fractions and cell concentrations were measured in submerged cultures of Saccharomyces cerevisiae, Escherichia coli, and Penicillium chrysogenum. Correlations for cell volume fractions with cell concentrations in fermentation media of the microorganisms were established accordingly. Other key properties of microorganisms, such as cell water content, wet cell density, and dry cell density, can also be obtained with the use of the current method. The results are in good agreement with data available in the literature.
