Functional microbiology of soda lakes

Current Opinion in Microbiology, 2015
Soda lakes represent unique permanently haloalkaline system. Despite the harsh conditions, they are inhabited by abundant, mostly prokaryotic, microbial communities. This review summarizes results of studies of main functional groups of the soda lake prokaryotes responsible for carbon, nitrogen and sulfur cycling, including oxygenic and anoxygenic ...

Microbial diversity of soda lakes

Extremophiles, 1998
Soda lakes are highly alkaline extreme environments that form in closed drainage basins exposed to high evaporation rates. Because of the scarcity of Mg2+ and Ca2+ in the water chemistry, the lakes become enriched in CO3(2-) and Cl-, with pHs in the range 8 to > 12. Although there is a clear difference in prokaryotic communities between the hypersaline

Starch-hydrolyzing bacteria from Ethiopian soda lakes

Extremophiles, 2001
Alkaliphilic bacteria were isolated from soil and water samples obtained from Ethiopian soda lakes in the Rift Valley area--Lake Shala, Lake Abijata, and Lake Arenguadi. Starch-hydrolyzing isolates were selected on the basis of their activity on starch agar plate assay.

Geochemistry of African Soda Lakes

2016
Soda lakes are those in which sodium and carbonate species dominate the dissolved ions. They form in hydrologically closed lake basins, where inflow is balanced primarily by evaporation. They are important habitats, closely tied to water resource issues in arid lands, and they support important economic activities.

Predation on planktonic ciliates in Kenyan soda lakes

Aquatic Ecosystem Health & Management, 2020
Ciliated protozoa are important components of the plankton of aquatic systems with ability to recycle nutrients and to link microbial food webs to metazoans. This is because they are numerous and have higher growth rates compared to other unicellular eukaryotes of similar size.

Phylogenetic diversity of bacteria in soda lake stratified sediments

Microbiology, 2014
Various previously developed techniques for DNA extraction from the samples with complex physicochemical structure (soils, silts, and sediments) and modifications of these techniques developed in the present work were tested. Their usability for DNA extraction from the sediments of the Kulunda Steppe hypersaline soda lakes was assessed, and the most ...
