[Method for studying the adaptation of Escherichia coli to the acidification of the medium].

Apparatus permitting to regulate the growth rate of turbidostat culture of microorganisms has been worked out. The process of adaptation of culture microorganisms to the medium acidity has been investigated by the stabilization of growth rate method. The correlation coefficients between adaptation time and changes of acid concentration in medium have been determined. The effect of aeration and density of microorganisms on the parameters of adaptation process has been considered. The conclusion concerning prospects of the growth rate stabilization method application for studying the regularities of culture microorganisms adaptation to the action of the stress has been made.
