Osmoadaptation in Representatives of Haloalkaliphilic Bacteria from Soda Lakes

Microbiology, 2005
The adaptation of microorganisms to life in brines allows two strategies: the accumulation of organic osmoregulators in the cell (as in many moderate halophiles, halomonads in particular) or the accumulation of inorganic ions at extremely high intracellular concentrations (as, for example, in haloanaerobes). To reveal the regularities of osmoregulation

Hydrogeochemistry of Big Soda Lake, Nevada: An alkaline meromictic desert lake

Geochimica et Cosmochimica Acta, 1984
Big Soda Lake, located near Fallon, Nevada, occupies an explosion crater rimmed by basaltic debris; volcanic activity apparently ceased within the last 10,000 years. This lake has been selected for a detailed multidisciplinary study that will ultimately cover the organic and inorganic hydrogeochemistry of water and sediments because the time at which ...

Bacteria, Archaea and Viruses of Soda Lakes

2016
The soda lake environment presents microorganisms with many combinations of physical and chemical extremes, amongst them extremes of alkaline pH, salinity (NaCl), temperature and incident radiation and water and oxygen availability. Despite this harsh regime, soda lakes are fertile habitats for an enormous diversity of alkaliphilic prokaryotic ...

[Carboanhydrase activity in halophilic anaerobes from soda lakes].

Mikrobiologiia, 2006
The activity and cellular localization of carboanhydrase (CA) in two alkaliphilic anaerobes growing in soda lakes at pH 9-10 was studied. CA activity in the cell extracts of the acetogenic bacterium Natroniella acetigena was comparable to that of the neutrophilic acetogens.

Microbial Diversity of Soda Lake Habitats

2003
A molecular approach has been utilised for an analysis of the procaryotic diversity in sediment samples from Lake Magadi, an African soda lake in the Rift Valley, Kenya. The molecular analysis included: a) extraction of total DNA; b) PCR-amplification using 16S rDNA primers specific for Bacteria or Archaea; c) ligation-independent cloning of PCR ...

Invertebrates of East African Soda Lakes

2016
Soda lakes are among the world’s most productive natural ecosystems, but the fauna consists of only a few specialized groups which can attain high biomass, seasonally or throughout the year. The invertebrate fauna is generally poor in species diversity. Protozoa are restricted to a few ciliates dominated by Condylostoma and Frontonia spp.

The Ecology of African Soda Lakes: Driven by Variable and Extreme Conditions

2016
East African soda lakes are extreme environments that force organisms to cope with high salinities, pH levels and turbidity, but are nonetheless amongst the most productive ecosystems worldwide. We provide an overview of the species inventory in these lakes, which, amongst other fascinating species, host the well-known cyanoprokaryote Arthrospira ...

Dipping into the Soda Lakes of East Africa

2016
Saline alkaline lakes are the focus of this book, but how do they form and how do they differ from freshwater lakes? We provide a brief introduction to soda lakes, their origin and their inhabitants, many of which are extremophiles. These closed lakes are highly sensitive ecosystems, and many experience the impacts of climate change.
