[Parameters of the function of cell distribution by size as related to the study of the mechanism of cell growth].

Distribution function of bacteria-rods according to their sizes is calculated assuming linear growth of cells between the divisions and step-like function of division (the division rate equals zero up to the moment when the cell reaches certain length L, then it has constant value A). An approximate analytical expression for the distribution function is obtained; the parameter L and A are calculated from the condition of best coincidence between the theoretical and experimental curves determined by I. A. Basnakyan and G. P. Dubinina (Mechnikov Research Institute of Virology) for continuous culture of typhoid bacteria.
