Bacteriophage of Halobacterium salinarium

Nature, 1974
Halobacterium salinarium is a member of the Halobacteria, a group of obligate, extremely halophilic organisms requiring at least 15% NaCl in their growth media. No bacteriophage has previously been found in association with members of this group.

Distribution of non-electrolytes in halobacterium cells I. Halobacterium marismortui

Biochimica et Biophysica Acta (BBA) - General Subjects, 1979
Halobacterium marismortui is an obligatorily halophilic species isolated from the Dead Sea. When inulin, fructose or glycerol are added to suspensions of bacteria, the amounts of these substances recovered from centrifuges pellets are more than could have been present in the extracellular space.

Comparison of purple membrane from Halobacterium cutirubrum and Halobacterium halobium

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1976
Direct comparison of purple membrane preparations from Halobacterium cutirubrum and Halobacterium halobium was carried out. Both preparations were found to be essentially identical with respect to their molecular weight, retinal content, lipid composition, fingerprinting of peptides from peptide digestion, electron micrographs and X-ray diffraction ...

Photoreactivation in Halobacterium cutirubrum

Canadian Journal of Microbiology, 1972
Extremely halophilic bacteria are able to survive in a natural environment exposed to high doses of ultraviolet irradiation. One such organism, Halobacterium cutirubrum, has been characterized to possess an extremely efficient photoreactivation from ultraviolet damage. A population irradiated to 1% survivors can photoreactivate to complete recovery of

Ultrastructure of two species of halobacterium

Journal of Ultrastructure Research, 1972
The morphology of a halobacterium from the Dead Sea has been compared with Halobacterium halobium. A freeze-fracture study has revealed two hexagonal patterns with repeating distances of 155 A and 65 A within layers of the cell-envelope. The larger pattern is a characteristic of the genus Halobacterium. The smaller has been identified with a surface of

Time-domain reflectometry studies onHalobacterium halobiumandHalobacterium marismortui

Physics in Medicine and Biology, 1996
The dielectric properties of Halobacterium halobium and Halobacterium marismortui measured over the frequency range 1 MHz to 1 GHz are compared with a single-shell model for interfacial polarization. In the case of Halobacterium halobium, the model shows excellent agreement with the experimental data for reasonable values of membrane and cytoplasmic ...

The expression of the superoxide dismutase gene in Halobacterium cutirubrum and Halobacterium volcanii

Canadian Journal of Microbiology, 1989
The gene encoding the Mn-containing superoxide dismutase (SOD) from Halobacterium cutirubrum has been cloned and sequenced. The deduced amino acid sequence is homologous to the sequences of Fe and Mn SODs from eubacteria. The high degree of amino acid identity between the archaebacterial and eubacterial proteins suggests that a SOD gene may have been ...

The membrane proteome of Halobacterium salinarum

PROTEOMICS, 2005
AbstractThe identification of 114 integral membrane proteins from Halobacterium salinarum was achieved using liquid chromatography/tandem mass spectrometric (LC/MS/MS) techniques, representing 20% of the predicted alpha‐helical transmembrane proteins of the genome.

Photoacoustic calorimetry of Halobacterium halobium photocycle

Biochemical and Biophysical Research Communications, 1980
Summary Enthalpy changes that occur during the photocycle of Halobacterium halobium purple membrane fragments have been measured on a millisecond time scale, using photoacoustic detection to obtain modulation photocalorimetric data. Details are given on the ways to obtain quantitative thermodynamic and kinetic information by this method.

Biogenesis of the purple membrane of Halobacterium halobium

Biophysics of Structure and Mechanism, 1977
A protein closely resembling the purple membrane protein pre-exists in the cell membrane of H. halobium prior to the appearance of functional bacteriorhodopsin. It is associated with a differentiated membranous structure which has been isolated on a sucrose gradient and appears to be a precursor of the purple membrane.
