title: [The biochemical mechanisms of energy support in Yersinia pseudotuberculosis cells at a low cultivation temperature].
abstract: The object of the study was the first stage of biological oxidation: the transfer of hydrogen electrons to the components of the respiratory chain of Y. pseudotuberculosis cells by NAD and NADF, coenzymes of pyridine-dependent dehydrogenases, having labile redox properties. The study revealed that in the low-temperature cultivation of Y. pseudotuberculosis an increase in the content of NAD and NADF was 1.5- to 2.0-fold greater than that observed at 37 degrees C, which was indicative of the fact that at low environmental temperature pyridine-dependent dehydrogenases played a more important role than at high temperature (37 degrees C). This, in combination with other mechanisms, made it possible for bacterial cells to maintain the level of energy metabolism, necessary for their survival, in the environment with low and constantly changing temperature.
