To determine the soluble starch consumption by Aerobacter aerogenes at an infinite dilution (when compared with cell concentration) the consumption rate of soluble starch in the broth was studied. This situation may be close to that in a feeding culture or a continuous culture.The amount of soluble starch in the broth could not be determined immediately because the concentration was very low. Moreover, the assayed value of soluble starch could not be obtained simultaneously along the time course of consumption.Consequently, in order to measure the change of soluble starch concentration in the broth immediately, it was determined to replace the consumption rate of soluble starch by the cells with the consumption rate of dissolved oxygen.This method showed good agreement with the theory used in the present paper, within the limits of the experiments performed. This method and the theory used in this paper may be useful for the analysis between carbon source and dissolved oxygen consumption by the cells in the presence of only a trace concentration of the carbon source. Also, the obtainable value "K" in the experiments may be useful for the aerated cultivation of microbial cells.
