ABSTRACT
The object of this work was to study the correlation between the growth rate of Candida valida and its cyanide-resistant respiration, as well as to investigate the effect of cyanide-resistant oxidase on biomass yield in the course of continuous cultivation of the yeast. The inhibition of cellular respiration by cyanide was shown to be directly correlated with the biomass yield. The intensity of cyanide-resistant respiration depended on the growth rate of the culture, and was lowest at the highest growth rates. It has been concluded that, when cyanide-resistant oxidase appears in the yeast cells, it functions simultaneously with the main respiratory chain. Cyanide-resistant respiration can be inhibited under the optimal conditions of the culture growth.
