title: [Analysis of the changes in the electrophysical and morphometric parameters in the growth and sporulation periods of Bacillus thuringiensis].
abstract: Changes in the electrophysical and morphometrical parameters of Bacillus thuringiensis cells were studied during their growth and differentiation using the electrophysical procedure with the frequency of an alternating electric field varying within a wide range. The appearing variations were interpreted on the basis of the data about changes in the concentration of vegetative cells and spores, the optical density and pH of the cultural broth, and the assimilation of glucose by the culture. The changes found in the electrophysical and morphometrical parameters were shown to accompany the main physiological processes in the cells. In principle, they can be used to control the process of cultivation.
