Phenol biodegradation by halophilic archaea

International Biodeterioration & Biodegradation, 2016
Abstract Phenol is a toxic aromatic compound produced as a by-product of industrial activities. Biological treatment of highly saline wastewaters containing phenol can be performed through halophilic microorganisms. In this study, the ability of halophilic archaeal isolates to degrade phenol was investigated.

Leben im Salz — Halophile Archaea

Biologie in unserer Zeit, 1995
AbstractDer größte Teil des Wassers auf diesem Planeten ist Meerwasser, welches eine relativ konstante Zusammensetzung anorganischer Salze enthält. In hypersalinen Gewässern dagegen sind höhere Salzkonzentrationen als im normalen Meerwasser vorhanden.

The information transfer system of halophilic archaea

Plasmid, 2011
Information transfer is fundamental to all life forms. In the third domain of life, the archaea, many of the genes functioning in these processes are similar to their eukaryotic counterparts, including DNA replication and repair, basal transcription, and translation genes, while many transcriptional regulators and the overall genome structure are more ...

Halophilic archaea in the human intestinal mucosa

Environmental Microbiology, 2010
Summary The human gastrointestinal tract microbiota, despite its key roles in health and disease, remains a diverse, variable and poorly understood entity. Current surveys reveal a multitude of undefined bacterial taxa and a low diversity of methanogenic archaea. In an analysis of the microbiota in colonic mucosal

Diversity of lactate metabolism in halophilic archaea

Canadian Journal of Microbiology, 1995
D-Lactate is readily used as a substrate for the growth of species of halophilic archaea belonging to the genera Haloferax and Haloarcula. L-Lactate was used by Haloferax species (Haloferax volcanii, Haloferax mediterranei) only when a substantial concentration of the D-isomer was also present in the medium.

Construction of composite transposons for halophilic Archaea

Canadian Journal of Microbiology, 1994
Transposons with selectable marker genes (e.g., antibiotic resistance) have been extremely useful tools in bacterial genetics but have not been found naturally in Archaea. We constructed synthetic transposons consisting of halobacterial ISH elements (ISH2, ISH26, or ISH28) flanking a mevinolin resistance determinant.

Nitrate Assimilation in Halophilic Archaea

2004
Nitrate is an important inorganic nitrogen source for plants and microorganisms. The physiology, enzymology and genetics of nitrate assimilation have been well studied in plants and bacteria (Campbell 1996; Lin and Stewart 1998); nonetheless, little is known at the biochemical, genetic or structural level of this process in halophilic Archaea.

Uranium association with halophilic and non-halophilic bacteria and archaea

Radiochimica Acta, 2004
Summary We determined the association of uranium with bacteria isolated from the Waste Isolation Pilot Plant (WIPP), Carlsbad, New Mexico, and compared this with known strains of halophilic and non-halophilic bacteria and archaea.

Bioprospecting Archaea: Focus on Extreme Halophiles

2016
In 1990, Woese et al. divided the Tree of Life into three separate domains: Eukarya, Bacteria, and Archaea. Archaea were originally perceived as little more than “odd bacteria” restricted to extreme environmental niches, but later discoveries challenged this assumption. Members of this domain populate a variety of unexpected environments (e.g.

Flagella of halophilic archaea: Differences in supramolecular organization

Biochemistry (Moscow), 2014
Archaeal flagella are similar functionally to bacterial flagella, but structurally they are completely different. Helical archaeal flagellar filaments are formed of protein subunits called flagellins (archaellins). Notwithstanding progress in studies of archaeal flagella achieved in recent years, many problems in this area are still unsolved.
