The Microbial Sulfur Cycle at Extremely Haloalkaline Conditions of Soda Lakes
Soda lakes represent a unique ecosystem with extremely high pH (up to 11) and salinity (up to saturation) due to the presence of high concentrations of sodium carbonate in brines. Despite theseExpand

Nitrification expanded: discovery, physiology and genomics of a nitrite-oxidizing bacterium from the phylum Chloroflexi
Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, a major process of the biogeochemical nitrogen cycle, but the recognized diversity of this guild is surprisingly low andExpand

An obligate methylotrophic, methane-oxidizing Methylomicrobium species from a highly alkaline environment
Abstract A new, obligately methylotrophic, methane-oxidizing bacterium, strain AMO 1, was isolated from a mixed sample of sediments from five highly alkaline soda lakes (Kenya). Based on its cellExpand

Oxidation of Inorganic Sulfur Compounds by Obligately Organotrophic Bacteria
New data obtained by the author and other researchers on two different groups of obligately heterotrophic bacteria capable of inorganic sulfur oxidation are reviewed. Among culturable marine andExpand

Denitrification at extremely high pH values by the alkaliphilic, obligately chemolithoautotrophic, sulfur-oxidizing bacterium Thioalkalivibrio denitrificans strain ALJD
Abstract.Thioalkalivibrio denitrificans is the first example of an alkaliphilic, obligately autotrophic, sulfur-oxidizing bacterium able to grow anaerobically by denitrification. It was isolated fromExpand

Bacterial diversity and activity along a salinity gradient in soda lakes of the Kulunda Steppe (Altai, Russia)
Here we describe the diversity and activity of sulfate reducing bacteria along a salinity gradient in four different soda lakes from the Kulunda Steppe (South East Siberia, Russia). For this purpose,Expand

Biomass, production and activity of bacteria in the Black Sea, with special reference to chemosynthesis and the sulfur cycle
Abundance, morphological composition, vertical distribution, production and activity of total bacterioplankton and its specific groups in the Black Sea were investigated in August–September 1989. TheExpand

Microbiological analysis of the population of extremely haloalkaliphilic sulfur-oxidizing bacteria dominating in lab-scale sulfide-removing bioreactors
Thiopaq biotechnology for partial sulfide oxidation to elemental sulfur is an efficient way to remove H2S from biogases. However, its application for high-pressure natural gas desulfurization needsExpand
