Halophilic anaerobic fermentative bacteria

Journal of Biotechnology, 2011
In hypersaline environments bacteria are exposed to a high osmotic pressure caused by the surrounding high salt concentrations. Halophilic microorganisms have specific strategies for balancing the osmotic pressure and surviving in these extreme conditions.

Abundance of integrons in halophilic bacteria

Canadian Journal of Microbiology, 2022
Integrons are genetic platforms used for expressing open reading frames (ORFs) arranged in gene cassettes. Excision and integration of gene cassettes are controlled by their associated integron integrase (IntI). Using IntegronFinder software, we analyzed all complete halophilic genomes available in the HaloDom database, along with selected partial ...

Are extreme halophiles actually “bacteria”?

Journal of Molecular Evolution, 1978
Comparative cataloging of the 16SrRNA of Halobacterium halobium indicates that the organism did not arise, as a halophilic adaptation, from some typical bacterium. Rather, H. halobium is a member of the Archaebacteria, an ancient group of organisms that are no more related to typical bacteria than they are to eucaryotes.

Halophilic Acetogenic Bacteria

1994
As outlined in preceding chapters of this book, acetogenic bacteria have a specialized physiological potential for the conservation of energy via the reduction of CO2 to acetate. They also harbor diverse catabolic processes and are found in unusual habitats.

Diversity of extremely halophilic bacteria

Extremophiles, 1998
In this review, the history of the classification of the family Halobacteriaceae, the extremely halophilic aerobic Archaea, is reviewed with some emphasis on the recently described new genera Halobaculum, Halorubrum, Natrialba, Natronomonas, and "Haloterrigena." Speculation is made about the evolutionary relationship between members of the ...

CAROTENOID PIGMENTS OF HALOPHILIC BACTERIA

Canadian Journal of Microbiology, 1960
The carotenoids of two yellow and four red halophilic bacteria were studied by chromatography on alumina. One yellow organism contained predominantly one pigment, or a group of closely related pigments similar to neurosporene, while the other contained the neurosporene-like pigments and appreciable amounts of an unknown pigment with absorption maxima ...

Halophilic and Haloalkaliphilic Sulfur-Oxidizing Bacteria

2013
Chemotrophic sulfur-oxidizing bacteria (SOB) represent an important functional group of microorganisms responsible for the dark oxidation of reduced sulfur compounds generated by sulfidogens. Until recently, only a single genus of halophilic SOB (Halothiobacillus) has been described, and nothing was known about the ability of this group to grow at high

Taxonomy of Halophilic Bacteria

2020
This chapter discusses the taxonomy of halophilic bacteria and the things that need to be done. The reader is strongly advised to accept a polythetic view, which means that no single character or character group should be used as the ultimate decision maker.

A SYNTHETIC MEDIUM FOR EXTREMELY HALOPHILIC BACTERIA

Canadian Journal of Microbiology, 1965
A synthetic medium, made up of 15 amino acids, adenylic and uridylic acid, glycerol, asparagine or ammonium chloride, and various salts, has been developed for halophilic bacteria. Halobacterium cutirubrum and Sarcina litoralis grew as well in this medium as in a complex medium containing casein hydrolysate and yeast extract.

30 Storage of Halophilic Bacteria

2006
Publisher Summary This chapter discusses those microbes that either require, or have optimal, sodium chloride concentrations at or above 6% (w/v). Some aspects of the storage of halophiles are similar to the storage of nonhalophilic bacteria. Some of the major differences are the result of the salinity of the medium in which the halophiles grow and ...
