Signal Transduction in Halobacteria
1989The search for photosynthetically efficient green light and the avoidance of inefficient blue light or lethal ultra-violet light allows halobacteria to survive by means of photosynthesis in a natural habitat of brines and salt ponds under strong sunlight.

Development of Shuttle Vectors for Halobacteria
1989Abstract : We have developed systems for genetic analysis of halophilic archaebacteria. These include (1) transformation systems which we have shown to work efficiently in at least three genera of halobacteria, (2) shuttle vectors which can be selected in either halobacteria or E.

On the gas vacuoles of the halobacteria
Archiv f�r Mikrobiologie, 1967The cells of Halobacterium sp., strain 5, contain a large number of highly refractile bodies of the type which Petter (1932) suggested were gas-filled vacuoles. The present studies support Petter's contention, but the evidence for the exact chemical nature of the vacuole content is still indirect.

Considerable progress has been made in recent years in the understanding of the function of molecular components in eucaryotic and eubacterial signal transduction chains. Among the well known examples are processes dependent on G-proteins in eucaryotes and processes dependent on receptors, called methyl-accepting proteins, in eubacteria.

Gas Vacuole Genes in Halobacteria
1991As previously shown by us there are two, highly homologous genes in Halobacterium halobium encoding gas vacuole proteins (GVP). These genes are located on the plasmid pHH1 (gene for GVP-A) and on the chromosome (gene for GVP-B). Recently we found that copies of both genes are also located on “minor circular DNA” (MCD), a heterogeneous collection of ...

Biotechnological potential of halobacteria.
Biochemical Society symposium, 1992The extremely halophilic archaebacteria (halobacteria) became an early focus of scientific interest owing to their role in salted food deterioration. In more recent times their peculiar physiology involving extreme adaptation to the salt environment and other unique features have allowed the development of other applied interests. Their similarities to

[47] The classification of halobacteria
1982Publisher Summary This chapter describes the classification of halobacteria. Recently, the halobacteria seemed to form a very homogeneous bacterial group, but this may have been largely becaue of uniformly utilized enrichment and isolation procedures.

Blue Light Effects in Halobacteria
1984Halophiles, methanogenes and thermoacidophiles to the present knowledge comprise the phylogenetic kingdom of archaebacteria, equally distant from eubacteria and eukaryotes [16]. Compared to the relatively small number of archaebacteria discovered so far, a wide range of physiological capabilities seems realized in this ancient branch of evolution ...

Isoprenoids and Bacteriorhodopsin in Halobacteria
1976Halophilic (salt-loving), thermophilic, acidophilic or psychrophilic organisms are all examples of biological adaption to ex- treme environmental conditions. Halophilic organisms are distinguished from marine organisms by the requirement of more than 3% NaCl in their growth medium, extremely halophilic bacteria require more than 15% NaCl for optimal ...
