Abstract:
The cell envelope of a number of marine, Gram-negative autotrophic bacteria has been examined by a combination of microscopic and chemical techniques. Variability in cell envelope structure was fairly common among the nitrifying, photosynthetic and methane-oxidizing bacteria. The presence of macromolecular subunits on the outer wall layers appeared to be relatively common and similarity in ultrastructure transcended species and physiological differences perhaps relating to common ecological patterns. The application of the freeze-etching technique to the study of the bacterial cell envelope has been particularly rewarding. Unlike ultrathin sections, the image obtained from a freeze-etching replica is three dimensional, facilitating the establishment of spatial relationships in the cell. Author
