I cannot find anything about how Thiomargarita maintains its unusual cell structure with cytoplasm restricted to the periphery. I can't even find anybody else wondering about this. Am I overlooking something obvious?

Elio replies:

Good point. I have assumed that the vacuole is membrane bound and that turgor pushes the thin cytoplasm against the envelope. But that turned out to be wrong. I did find a lot of information here See here http://link.springer.com/referenceworkentry/10.1007%2F0-387-30746-X_47
Fig. 7 has some good sections and they show no membrane. Some sort of phase partition must keeps the cytoplasm distinct form the vacuole. Plus turgor?
