[The effect of the pH of the medium on induced autolysis in populations of enterobacteria].
Changes in pH in the process of the induced autolysis of salmonellae and Escherichia coli were studied. The induced autolysis of enterobacterial populations was studied in connection with the acidity values of the medium in which the process was carried out. The pH of extracellular fluid, the optical density of cell suspension, the content of total protein and amino nitrogen were analyzed. Enterobacterial populations were found to be capable of the self-regulation of the acidity of the medium in the process of induced autolysis. The study revealed that the most Intensive autolysis of bacteria took place when the process was carried out in extreme alkaline values of pH.
