[Extremophilic microorganisms: biochemical adaptation and biotechnological application (review)].

The analysis of modern data on biochemical adaptation of microorganisms for living in extreme conditions is presented in this review. Special attention has been paid to the analysis of adaptive responses of microorganisms to the conditions of increased radiation at the molecular and cellular levels. The data on the practical application of extremophils and extremoenzymes, synthesized by them, biologically active substances, biopolymers and so on, have been systematized.
