SHORT COMMUNICATION Isolation of Extremely Halophilic Bacteria Able to Grow in Defined Inorganic Media with Single Carbon Sources
TLDR
Pigmented pleomorphic rods morphologically similar to Halobacterium volcanii were isolated from a salt pond near Alicante, Spain and distinguished from currently recognized species by the absence of complex nutrient requirements, a rapid growth rate, nutritional versatility and salt-dependent pigment production.Abstract:
Summary: Pigmented pleomorphic rods morphologically similar to Halobacterium volcanii were isolated from a salt pond near Alicante, Spain. The salt concentration range for growth (10 to 35 %, w/v, total salts) was more moderate than that typical of Halobacterium. Twenty-two strains were characterized as members of the genus Halobacterium, but were distinguished from currently recognized species by the absence of complex nutrient requirements, a rapid growth rate, nutritional versatility and salt-dependent pigment production. A typical strain (R-4) has been deposited in the Czechoslovak Collection of Microorganisms, no. CCM 3361.read more

TL;DR: A large number of the strains could be tentatively assigned to the genus Vibrio, suggesting that this may be an abundant taxon of moderately halophilic Gram-negative rods in solar salterns.

TL;DR: The results show the existence of at least three groups with the taxonomic level of genus Halobacterium, and propose the two new genera Haloarcula and Haloferax for the nomenclatural accomodation of the three groups.

Transcription at different salinities of Haloferax mediterranei sequences adjacent to partially modified PstI sites
TL;DR: Two genomic sequences from the halophilic archaeon Haloferax mediterranei, where the authors had found PstI restriction‐pattern modifications depending on the salinity of the growth medium, have been studied and a markedly salt‐dependent differential expression has been detected in the nearby regions.

An improved technique for staining red halophilic bacteria
TL;DR: Various workers attempting to stain the halophilic bacteria which are commonly responsible for the red discoloration of salted hides and salted fish have been unanimous in reporting major difficulties.

Halobacterium volcanii spec. nov., a Dead Sea halobacterium with a moderate salt requirement.
TL;DR: The organism grew well in media containing magnesium chloride in the concentrations found in the Dead Sea; Halobacterium volcanii is therefore remarkably well fitted for life in theDead Sea.
