Genetic transfer in Halobacterium volcanii [PDF]
Journal of Bacteriology, 1985 Auxotrophic mutants of Halobacterium volcanii generated by chemical mutagenesis were used to demonstrate a native genetic transfer system in this extremely halophilic member of the class Archaeobacteria.

Chemosensory responses of Halobacterium halobium [PDF]
Journal of Bacteriology, 1979 Responses of Halobacterium halobium cells to chemical stimuli have been shown by a capillary technique. Cells were attacted by D-glucose and several amino acids and repelled by phenol. Certain chemicals, such as acetate, benzoate, indole, and NiSO4, that are known to act as repellents of Escherichia coli cells served as attractants for Halobacterium ...

Picosecond events in the photochemical cycle of the light-driven chloride-pump halorhodopsin [PDF]
, 1985 The early events in halorhodopsin after light excitation are studied with picosecond time resolution. Absorption and fluorescence measurements show that the electronically excited state of the incorporated retinal has a lifetime of 5 ps. Within that time

Photophosphorylation in Halobacterium halobium [PDF]
Proceedings of the National Academy of Sciences, 1974 Halobacterium halobium cells grown under semi-anaerobic conditions convert part of their cell membrane into “purple membrane” which contains a rhodopsin-like protein, bacteriorhodopsin. Under anaerobic conditions in the dark the ATP content of such cells decreases sharply. Either light or oxygen restores the ATP

Inference of expanded Lrp-like feast/famine transcription factor targets in a non-model organism using protein structure-based prediction. [PDF]
PLoS ONE, 2014 Widespread microbial genome sequencing presents an opportunity to understand the gene regulatory networks of non-model organisms. This requires knowledge of the binding sites for transcription factors whose DNA-binding properties are unknown or difficult

Genetic variability in Halobacterium halobium [PDF]
Journal of Bacteriology, 1981 Halobacterium halobium exhibits an extraordinary degree of spontaneous variability. Mutants which are defective in the formation of gas vacuoles (vac) arise at a frequency of 10(-2). Other easily detectable phenotypes, like the synthesis of bacterioruberin (Rub) or the synthesis of retinal (Ret) and bacterio-opsin (Ops), the two components which form ...

Systems analysis of bioenergetics and growth of the extreme halophile Halobacterium salinarum [PDF]
, 2009 Halobacterium salinarum is a bioenergetically flexible, halophilic microorganism that can generate energy by respiration, photosynthesis, and the fermentation of arginine.

Identification of Archaea species from hot spring water in Hammam AL-Allel at Mosul Governorate
مجلة مركز بحوث التقنيات الاحيائية, 2014 Isolate, Identify of some species belonging to Archaea from water of hot and sulphid springs in Hammam Al-Allel City/ Nenavah Governorate. Seventy five samples were collected from hot springs during 2012. The Archaea species were isolated using ordinary

Model Construction and Analysis of Respiration in Halobacterium salinarum. [PDF]
PLoS ONE, 2016 The archaeon Halobacterium salinarum can produce energy using three different processes, namely photosynthesis, oxidative phosphorylation and fermentation of arginine, and is thus a model organism in bioenergetics.

BMC Genetics, 2007 Background Archaea are prokaryotic organisms with simplified versions of eukaryotic transcription systems. Genes coding for the general transcription factors TBP and TFB are present in multiple copies in several Archaea, including Halobacterium sp. NRC-1.
