[Correlation of the basic growth parameters of microorganisms in the presence of surface-active substances].

The object of this work was to study the effect of the nature of surfactants on the solubility of oxygen in the cultural broth. A correlation was established between the concentration of a surfactant and the concentration of dissolved oxygen, the specific rate of growth and the activity of dehydrogenases. Apparently, the biological action of surfactants on the parameters of growth of the yeast Candida tropicalis K-14 in the process of fermentation should be attributed to the formation of micelles.
