Thioalkalimicrobium aerophilum gen. nov., sp. nov. and Thioalkalimicrobium sibericum sp. nov., and Thioalkalivibrio versutus gen. nov., sp. nov., Thioalkalivibrio nitratis sp.nov., novel and
Thioalkalivibrio was not related to any known chemolithoautotrophic taxa, but was distantly associated with anaerobic purple sulfur bacteria of the genus Ectothiorhodospira, forming a new alkaliphilic lineage in this cluster.
Potential soil reinforcement by biological denitrification
Abstract Currently new ground reinforcement techniques are being developed based on microbially induced carbonate precipitation (MICP). Many studies on MICP use microbially catalyzed hydrolysis of
Diversity, Activity, and Abundance of Sulfate-Reducing Bacteria in Saline and Hypersaline Soda Lakes
The results indicate the presence of diverse and active SRB communities in these extreme ecosystems.
The Microbial Sulfur Cycle at Extremely Haloalkaline Conditions of Soda Lakes
Microbiological analysis indicated a domination of three groups of haloalkaliphilic autotrophic sulfate-reducing bacteria belonging to the order Desulfovibrionales, including the most physiologically diverse genus Thioalkalivibrio, which covers the whole spectrum of salt/pH conditions present in soda lakes.
Nitrification expanded: discovery, physiology and genomics of a nitrite-oxidizing bacterium from the phylum Chloroflexi
The surprising discovery of a chemolithoautotrophic nitrite oxidizer that belongs to the widespread phylum Chloroflexi not previously known to contain any nitrifying organism significantly extends the known diversity of nitrify organisms and likely will have implications for future research on nitrification in natural and engineered ecosystems.

  • 1 July 2005
Analysis of 19 recent publications from 1999 to 2005 demonstrated that almost none of them contain solid proof of the potential of a novel organism to grow at pH above 10 (the media not buffered properly, final pH values not measured or indicated).
Discovery of extremely halophilic, methyl-reducing euryarchaea provides insights into the evolutionary origin of methanogenesis
The discovery of extremely halophilic, methyl-reducing methanogen related to haloarchaea provides insights into the origin of methanogenesis and shows that the strategies employed by methanogens to thrive in salt-saturating conditions are not limited to the classical methylotrophic pathway.
Isolation and characterization of a novel facultatively alkaliphilic Nitrobacter species, N. alkalicus sp. nov.
The new isolates from the alkaline habitats are described as a new species of the genus Nitrobacter, N. alkalicus, on the basis of their substantial morphological, physiological, and genetic differences from the recognized neutrophilic representatives of this genus.
Dethiobacter alkaliphilus gen. nov. sp. nov., and Desulfurivibrio alkaliphilus gen. nov. sp. nov.: two novel representatives of reductive sulfur cycle from soda lakes
On the basis of the phenotypic and phylogenetic data, strains AHT 1 and AHT 2 are proposed as new genera and species Dethiobacter alkaliphilus and Desulfurivibrio alk aliphilus, respectively.
