Abstract
The ultrastructure of seven Thiobacillus species was studied. The structure of their cell envelopes is similar, if not identical, to that found in other gram-negative bacteria. Obvious differences were noted in the middle layer of the cell envelope of the seven cultures. Polyhedral inclusion bodies were apparent in four of the organisms: T. thioparus, T. neapolitanus, T. intermedius , and T. thiooxidans . Lamellar bodies, similar to those present in certain photosynthetic bacteria were found in a few cells of T. thioparus . Structures resembling mesosomes were discovered in T. dinitrificans . A few cells of T. intermedius possessed paracrystalline bodies. Other inclusions, probably volutin and polysaccharide, were present in some of the cultures.
