Cleavage planes in the envelope of Aquaspirillum bengal.
The cell surface of Aquaspirillum bengal was devoid of superficial wall structure. When cells were freeze-cleaved and etched, multiple fracture planes through the cell envelope were exposed, which was unusual for an aquaspirillum. These included both convex and concave surfaces and they are compared with those of other gram-negative bacteria.
