title: [Study of phototrophic purple bacterium Rhodobacter sphaeroides cell morphology of wild-type and ipt-transformant by atomic force and electron microscopy].
abstract: A comparative study of phototrophic purple bacterium Rhodobacter sphaeroides cell morphology of wild-type and ipt-transformant was done by atomic force and electron microscopy. It was shown that transformation led to a decrease in the number or total disappearance of the flagella, as well as to changes in the structure of the outer membrane of the bacteria cell wall. On the wild-type cell surface phage-like structures were found, and in transformed cells at their places hollows were identified. This study significantly extends an understanding of the changes occurring in the ipt-transformants of phototrophic purple bacterium Rhodobacter sphaeroides. This investigation not only confirmed earlier obtained data about the differences in the wild-type and ipt-transformant phototrophic purple bacteria cell wall, but also showed fine changes in the structure of its outer membrane.
