High rates of sulfidogenesis were observed in sediments from hypersaline soda lakes. Anaerobic enrichment cultures at 2 M Na(+) and pH 10 inoculated with sediment samples from these lakes produced sulfide most actively with sulfite and thiosulfate as electron acceptors, and resulted in the isolation of three pure cultures of extremely natronophilic sulfidogenic bacteria. Strain ASO3-1 was isolated using sulfite as a sole substrate, strain AHT 8 with thiosulfate and formate, and strain AHT 6…

TLDR
Two novel haloalkaliphilic bacteria with dissimilatory sulfidogenic metabolism were recovered from syntrophic associations obtained from anaerobic sediments of hypersaline soda lakes in Kulunda Steppe and proposed to represent two novel species: Desulfonatronospira sulfatiphila sp.
Haloalkaliphilic spore-forming sulfidogens from soda lake sediments and description of Desulfitispora alkaliphila gen. nov., sp. nov.
TLDR
The ability of AHT17 to use sulfite explained the stability of the original coculture of the two clostridia—one member forming sulfite from thiosulfate and another consuming it.
Desulfonatronobacter acidivorans gen. nov., sp. nov. and Desulfobulbus alkaliphilus sp. nov., haloalkaliphilic heterotrophic sulfate-reducing bacteria from soda lakes.
TLDR
Two types of heterotrophic sulfate-reducing bacteria (SRB) were isolated from anoxic sediments of hypersaline soda lakes in Kulunda Steppe (Altai, Russia) and are proposed to represent two novel taxa, Desulfonatronobacter acidivorans gen. nov. and Desulfobulbus alkaliphilus sp.nov.
Sulfur-dependent respiration under extremely haloalkaline conditions in soda lake 'acetogens' and the description of Natroniella sulfidigena sp. nov.
TLDR
Apparently, in the absence of specialized respiratory sulfidogens, primarily fermentative bacteria that are well adapted to extreme salinity may take over an uncharacteristic ecological function.
Desulfurispira natronophila gen. nov. sp. nov.: an obligately anaerobic dissimilatory sulfur-reducing bacterium from soda lakes
TLDR
The soda lake isolates are proposed as a new genus and species, Desulfurispira natronophila, which uses either elemental sulfur/polysulfide or arsenate as electron acceptor and a few simple organic compounds as electron donor and carbon source.
Desulfonatronum zhilinae sp. nov., a novel haloalkaliphilic sulfate-reducing bacterium from soda Lake Alginskoe, Trans-Baikal Region, Russia
TLDR
The isolate is proposed as a representative of a novel species Desulfonatronum zhilinae with the type strain Al915-01T (=VKM B-2744T = DSM 26338T), which was able to grow lithoheterotrophically with sulfate and molecular hydrogen if acetate was added as a carbon source.
Propionate and butyrate dependent bacterial sulfate reduction at extremely haloalkaline conditions and description of Desulfobotulus alkaliphilus sp. nov.
TLDR
Experiments with sediments from soda lakes of Kulunda Steppe showed sulfide production with sulfate as electron acceptor and propionate and butyrate (but not acetate) as an electron donor at a pH 10–10.5 and a salinity 70–180 g l−1.
Culturable diversity of lithotrophic haloalkaliphilic sulfate-reducing bacteria in soda lakes and the description of Desulfonatronumthioautotrophicum sp. nov., Desulfonatronum thiosulfatophilum sp. nov., Desulfonatronovibrio thiodismutans sp. nov., and Desulfonatronovibrio magnus sp. nov.
TLDR
On the basis of phylogenetic, genotypic and phenotypic characterization of the novel soda lake SRB isolates, two novel species each in the genera Desulfonatronum and Desulf onatronovibrio are proposed.
Desulfosporosinus acididurans sp. nov.: an acidophilic sulfate-reducing bacterium isolated from acidic sediments
TLDR
Three strains of sulfate-reducing bacteria (M1T, D, and E) were isolated from acidic sediments and characterized phylogenetically and physiologically and represent a novel species within the genus Desulfosporosinus, for which the name Desulfo porosinus acididurans sp.
Desulfohalophilus alkaliarsenatis gen. nov., sp. nov., an extremely halophilic sulfate- and arsenate-respiring bacterium from Searles Lake, California
TLDR
It is concluded that strain SLSR-1 can only achieve growth via arsenate-reduction under the current chemical conditions prevalent at Searles Lake.

TLDR
The novel isolate is a lithoheterotroph and a facultative lithoautotroph that is able to grow on hydrogen without an organic source of carbon and is resistant to kanamycin and gentamicin, but sensitive to chloramphenicol and tetracycline.

A new strictly anaerobic, gram-negative bacterium was isolated from the sediment of a freshwater lake after enrichment with thiosulfate as the energy source and was shown to be related to, but distinct from members of the genus Desulfobulbus on the basis of physiological characteristics and by comparative sequence analysis of its 16S rDNA.
