The Cell Wall of Marine Autorophic Bacteria.
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)
