Abstrakt: Within temperature intervals 30-40 degrees C for bacterial suspension of E. coli and 24-34 degrees C for B. flavum the extracellular medium exists in a specific state. Water in the extracellular medium is stabilized by increased hydrophobicity of extracellular protein molecules surface due to proteins conformational change. The total amount of UV-absorbing metabolites is decreased as a result of activation of microorganisms transport systems. The temperature intervals of these processes are different for both types of the microorganisms and coincide with their temperature optima of vital activity.
