Abstract
SUMMARY: The envelope of Escherichia coli B exhibited areas at which cell wall and protoplasmic membrane were intimately associated. These areas became visible in ultrathin sections after the bacteria had been fixed and embedded in plasmolysed state. At numerous areas the protoplasmic membrane was observed to adhere to the wall, while the protoplast had shrunk. Duct-like extensions of the protoplasmic membrane were thus formed. Two hundred to 400 of these wall membrane associations are found per bacterium of E. coli B. In a number of cells the chromosomal material is seen in close proximity or connected to a wall membrane association.Keywords
