Summary

  1. 1.

    The cell envelope of frozen-etchedN. europaea cells showed a smooth outer boundary

    revealed by etching. Splitting of the outer cell envelope occurred frequently and resulted in the appearance of a smooth convex fracture face

    presumably corresponding to a concave fracture face

    showing a dense arrangement of subunits.

  2. 2.

    The convex fracture faces of the cytoplasmic membrane and intracytoplasmic membranes were very similar. The intracytoplasmic membranes covered the entire cell length and became constricted in dividing cells. Their precise arrangement depended on the conditions in which the cells had been frozen.
