Исследование адсорбции бактериофага фаb-sp7 на клеточной поверхности Azospirillum brasilense Sp7

The bacteriophage ΦAb-Sр7 was isolated from the cells of the azospirillum brasilense sp7. The morphology, size of the gram-negative colonies, and range of lytic activity against other strains and species of the genus Azospirillum was tested. The isolated phage DNA was examined using electrophoretic and restriction analysis, and the size of the genome were established. The electron microscopy results show that the phage (capsid) has a strand-like form. The electron microscopy study of the bacteriophage ΦAb-Sр7 adsorption on the A. brasilense Sp7 bacterial surface was performed.
