Anaerobic growth of halobacteria
TLDR
In this paper, an energy-transducing pathway in halobacteria is described, where arginine mediates substrate level phosphorylation and allows the cells to grow anaerobically.Abstract:
An energy-transducing pathway in halobacteria is described. Arginine mediates substrate level phosphorylation and allows the cells to grow anaerobically. Bacteriorhodopsin plus light can function as an alternative energy source under these conditions, provided the cells contain the pigment when transferred to the anaerobic environment. Therefore the selection of mutants functionally defective in ATP synthase or bacteriorhodopsin becomes possible.read more

TL;DR: Examinination of microbial diversity in environments of increasing salt concentrations indicates that certain types of dissimilatory metabolism do not occur at the highest salinities.

Biosynthesis and metabolism of arginine in bacteria.
TL;DR: This paper presents a meta-modelling study of the regulation of metabolic flow in E. coli through the pathways of Arginine, Citrulline, and Ornithine and concludes that these pathways are dominated by bacteria with extensive repression control.

Anaerobic Metabolism: Linkages to Trace Gases and Aerobic Processes
TL;DR: A review of anaerobic metabolism emphasizes aerobic oxidation, because the two processes cannot be separated in a complete treatment of the topic as mentioned in this paper, which is process oriented and highlights the fascinating microorganisms that mediate biogeochemistry.

Proposed Minimal Standards for Description of New Taxa in the Order Halobacteriales
TL;DR: The minimal standards include information on the following characteristics: cell morphology; motility; pigmentation; the requirement for salt to prevent cell lysis; optimum NaCl and MgCl2 concentrations for growth and range of salt concentrations enabling growth; temperature and pH ranges for growth.

Photophosphorylation in Halobacterium halobium
TL;DR: Halobacterium halobium cells grown under semi-anaerobic conditions convert part of their cell membrane into "purple membrane" which contains a rhodopsin-like protein which uses the resulting chemiosmotic gradient for ATP synthesis.

Biosynthesis of the purple membrane of halobacteria
TL;DR: Halobacteria are extremely specialized organisms that live exclusively in saturated solutions of common salt, and the cell membrane of these bacteria exhibit insular regions which can be isolated by membrane fractionation.

Light inhibition of respiration in Halobacterium halobium.
TL;DR: Measurements are reported which allow quantitation of light energy conversion in H. halobium on the basis of this light inhibition of respiration and a function of bacteriorhodopsin in the purple membrane was postulated.
