Abstract
The cell surfaces of Halobacteria are seen by shadow casting to be composed of a hexagonal lattice of morphological units with a centre-to-centre spacing of approximately 15 nm. Preparations of virtually salt-free envelopes from Halobacterium volcanii, isolated from the Dead Sea, can be obtained by freezing and thawing the cells, treatment with 1 μg/ml of DNAase and suspension in 10 mM CaCl2 and have enabled a three-dimensional analysis of the surface layer by negative staining.
