title: Structure of the surface of spores and morphological-physiological properties of individual strains of Bacillus megaterium.
abstract: The structure of the surface of spores of 10 strains of Bacillus megaterium was investigated by the method of carbon replicas. They were separated into three groups according to the peculiarities of the structural organization of the surface of the spores. The combination of other morphological and physiological-biochemical characteristics of these strains was characteristic of the species Bac. megaterium. Strains with differences in the structure of the spore surface also showed similarities in other peculiarities of carbohydrate and nitrogen metabolism studied in the work, as well as in the primary structure of DNA. The date obtained lead to the conclusion that structural differences in the surface of the spores cannot be considered a sufficient basis for isolating the bacteria studied into separate taxonomic groups.
