[Changes in the cell size of Escherichia coli M-17 during induced destruction].
The autolysis of E. coli, induced by their deprivation of nutrition in combination with the action of oleic acid and a temperature of 45 degrees C, was studied. The study revealed that an increase in the number of cells during 4 hours after the induction of the process was accompanied by a decrease in their size and an increase in the surface/volume ratio. Changes in the size of bacteria in the course of induced destruction resulting from their deprivation of nutrition in combination the action of oleic acid and a temperature of 45 degrees C were found to occur in two phases: (1) a decrease in size with an increase in the surface/volume ratio; (2) an increase in size with a decrease in the surface/volume ratio.
