Kurzbeschreibung (Abstract)

Extrachromosomal, covalently closed circular deoxyribonucleic acid has been isolated from different species of halobacteria. Three strains of Halobacterium halobium and one of Halobacterium cutirubrum, all of which synthesize purple membrane (Pum+) and bacterioruberin (Rub+), contain plasmids of different size which share extensive sequence homologies. One strain of Halobacterium salinarium, another one of Halobacterium capanicum, and two new Halobacterium isolates from Tunisia, which are also Pum+ Rub+, do not harbor covalently closed circular deoxyribonucleic acid but contain sequences, presumably integrated into the chromosome, which are similar if not identical to those of pHH1, i.e., the plasmid originally isolated from H. halobium. Three other halophilic strains, Halobacterium trapanicum, Halobacterium volcanii, and a new isolate from Israel, do not carry pHH1-like sequences. These strains are, by morphological and physiological criteria, different from the others examined and harbor plasmids unrelated to pHH1.
