IV-85 was examined by thin section and freeze-etch techniques. The morphology of this marine isolate was similar to that of terrestrial species of Thiobacillus. Decline phase preparations showed a marked degeneration of internal organization. Membrane vesicles, characteristically bound by a trilaminar membrane, were observed only in preparations of decline phase cells. The examination of freeze-etched preparations of both first and second log phase organisms showed membrane-bound polyhedral inclusion bodies in intact cells and a characteristically rippled envelope. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-85-1-130
