The possible mechanisms of the adaptation of microbial populations to low positive temperatures

Biologically low temperature was studied for its effect on the survival of populations and their biochemical and molecular-genetical state. The research was carried out on Yersinia pseudotuberculosis and Shigella sonnei models. It is established that the process of low-temperature adaptation of the...

Description
Summary:	Biologically low temperature was studied for its effect on the survival of populations and their biochemical and molecular-genetical state. The research was carried out on Yersinia pseudotuberculosis and Shigella sonnei models. It is established that the process of low-temperature adaptation of the populations may occur either at the level of the whole population with participation of inducible cold isoenzymes or at the level of a part of population, the temperature being a selection factor of the adapted cells.
