Ultrastructure of Spermine-Treated Escherichia Coli, Including a Polar Organelle Concerned With Envelope Synthesis

Abstract

Sections of spermine-treated, wild-type E. coli W showed intracytoplasmic membranes and tubules, both of which were associated with the nucleoplasm. Ribosomes were frequently arranged linearly or in clusters and linked by fibrils. DNA fibrils were rarely detected.
