title: [The effect of physicochemical environmental factors on the growth of gram-positive bacterial dissociants].
abstract: The growth of R-, S- and M (g)-dissociants of Streptococcus lactis, Bacillus coagulans, Rhodococcus rubropertinctus under the action of some physico-chemical factors: temperature, pH, ultraviolet (UV) rays, high concentration of NaCl and storage have been compared. R-variants gain selective advantage under the influence of UV-irradiation, high temperature and storage; S-variants--at decreasing of active pH of medium; M (g)-variants--at decreasing of growth temperature, high values of pH, increased NaCl concentration. The dissociation has been concluded to enlarge the limits of the species survival.
