Comparative in silico analysis of PCR primers suited for diagnostics and cloning of ammonia monooxygenase genes from ammonia-oxidizing bacteria [PDF]

, 2008
Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB).

Metabolic adaptation and trophic strategies of soil bacteria - C1- metabolism and sulfur chemolithotrophy in Starkeya novella

Frontiers in Microbiology, 2013
The highly diverse and metabolically versatile microbial communities found in soil environments are major contributors to the global carbon, nitrogen and sulfur cycles. We have used a combination of genome –based pathway analysis with proteomics and gene

Hydrochemical gradients driving extremophile distribution in saline and brine groundwater of southern Poland

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
The solute composition differentiates high‐salinity groundwaters of southern Poland into three genetic, aquifer‐related groups. Sulphate and hydrogen carbonate concentrations relative to chloride, along with total salinity, are the key factors controlling microbial communities. Methanogens dominate in sulphate‐poor brines of the Carpathian Foredeep and

Microbial communities reveal niche partitioning across the slope and bottom zones of the challenger deep

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
The physical–chemical characteristics related to depth across the slope and bottom, along with the distinct hydrology between seawaters and sediments, influence the microbial communities in the challenger deep of the Marianas trench. This leads to niche differentiation in community composition and metabolic functions, which is a result of niche ...

Genome implosion elicits host-confinement in Alcaligenaceae: evidence from the comparative genomics of Tetrathiobacter kashmirensis, a pathogen in the making.

PLoS ONE, 2013
This study elucidates the genomic basis of the evolution of pathogens alongside free-living organisms within the family Alcaligenaceae of Betaproteobacteria. Towards that end, the complete genome sequence of the sulfur-chemolithoautotroph Tetrathiobacter

Comparative proteomics of a versatile, marine, iron‐oxidizing chemolithoautotroph

Environmental Microbiology, Volume 26, Issue 6, June 2024.
In this study, we identified proteins that were upregulated under iron‐oxidizing conditions. Notably, we highlight a periplasmic di‐heme cytochrome c that is associated with a putative redox complex spanning the inner membrane, periplasm, outer membrane, and extracellular space.

Expression of the arsenite oxidation regulatory operon in Rhizobium sp. str. NT-26 is under the control of two promoters that respond to different environmental cues [PDF]

, 2017
Rhizobium sp. str. NT-26 is a gram-negative facultative chemolithoautotrophic arsenite oxidiser that has been used as a model organism to study various aspects of arsenite oxidation including the regulation of arsenite oxidation.

Allochthonous Groundwater Microorganisms Affect Coastal Seawater Microbial Abundance, Activity and Diversity

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 2, February 2024.
Abstract Submarine groundwater discharge (SGD) is a globally important process supplying nutrients and trace elements to the coastal environment, thus playing a pivotal role in sustaining marine primary productivity. Along with nutrients, groundwater also contains allochthonous microbes that are discharged from the terrestrial subsurface into the sea ...
