Abstract
The elasticity modulus of Escherichia coli cell walls was found to change in the course of growth of the culture. It decreased in the middle of the exponential phase, apparently as a result of intensification of biosynthetic and related to them transport processes at this period. If the cells were treated with EDTA, their elasticity modulus was lower, by an order of magnitude, than that of the control cell walls. If the cells were treated with lysozyme, the elasticity modulus of their walls decreased by three orders of magnitude. The elasticity modulus of cell walls was less in gram-positive rods than in E. coli. The elasticity modulus of spherical cells cannot be determined using this technique.
