An electron microscopic examination of selected species of the genus Thiobacillus was undertaken using the techniques of chemical fixation and freeze etching. The architecture of the cells was typical of gram negative bacteria. The multilayered cell envelope was revealed as a complex of smooth, rough, and particle studded membranes. The particles which covered the outer plasma membrane (convex surface) appeared to contain a differentiated region which might permit a channeling between the exterior and interior of the cell. Inclusion bodies, including paracrystalline arrays, carboxysomes, and granules were present.
