[An electron microscopic study of the structure of Erwinia carotovora 268 bacteria].

The electron-microscopic studies have shown that the bacterium Erwinia carotovora 268 (a producer of L-asparaginase) does not differ essentially from other representatives of enterobacteria. When growing on the artificial nutrient medium M9, the division of bacteria is inhibited and the bacterial cell itself elongates. Certain functionally specified structural peculiarities such as the formation of the protein microcapsule, formation of cavities and compacted sites of the cytoplasm and mucus on the cell poles are typical of bacteria, that is associated with the synthesis of L-asparaginase and erwiniocinogeny.
