[The adhesive properties of S and R mutants of Salmonella minnesota during batch cultivation]

The study of the adhesive, surface-electrical and hydrophobic properties of S. minnesota S- and R-mutants in the process batch cultivation has revealed that the maximum values of the above parameters are characteristic of the stationary phase of culture growth and their minimum values, of the end of the lag phase. Electrophoretic mobility and adhesiveness increase from S- to Re-chemotype. The surface of Salmonella S-form is more hydrophilic, than in R-mutants which are indistinguishable in the degree of their hydrophobic properties. The heterogeneity of the populations under study with respect to the electrophoretic mobility and adhesiveness of cells has been detected.
