‘Candidatus Desulfonatronobulbus propionicus’: a first haloalkaliphilic member of the order Syntrophobacterales from soda lakes

Propionate can be directly oxidized anaerobically with sulfate as e-acceptor at haloalkaline conditions either incompletely to acetate (an example is Desulfobulbus alkaliphilus), or completely (for example by the members of genus Desulfonatronobacter). An enrichment with propionate at methanogenic conditions (without sulfate) inoculated with...

Desulfonatronobacter acetoxydans sp. nov.,: A first acetate-oxidizing, extremely salt-tolerant alkaliphilic SRB from a hypersaline soda lake

Recent intensive microbiological investigation of sulfidogenesis in soda lakes did not result in isolation of any pure cultures of sulfate-reducing bacteria (SRB) able to directly oxidize acetate. The sulfate-dependent acetate oxidation at haloalkaline conditions has, so far, been only shown in two syntrophic associations of novel...
