[The biochemical characteristics of the products of the vital activity of Yersinia pseudotuberculosis in relation to the cultivation temperature].

For the first time the metabolic processes, taking place during "cold" cultivation of Y. pseudotuberculosis and involving organic and amino acids, were shown to be more economical, thus permitting the bacteria to maintain its viability for a rather long time at low temperature without the need to consume these substances from outside. At higher temperature the bacteria switches its metabolic paths to the consumption of nutrient substances in greater amounts from outside, increasing its constructive metabolism.
