The microbial sulfur cycle at extremely haloalkaline conditions of soda lakes

open access: yesFrontiers in Microbiology, 2011
Microbial sulfur cycle is among the most active in soda lakes. Oxidative part of the cycle is driven by chemolithoautotrophic haloalkaliphilic sulfur-oxidizing bacteria.

Distribution and Succession of Microbial Communities Along the Dispersal Pathway of Hydrothermal Plumes on the Southwest Indian Ridge

open access: yesFrontiers in Marine Science, 2020
The distribution and succession of microbial communities along the dispersion path of hydrothermal plumes has not been well investigated. In this study, we collected several types of samples from the Longqi hydrothermal field located on the Southwest ...

Biofouling of crypts of historical and architectural interest at la Plata Cemetery (Argentina) [PDF]

open access: yes, 2012
Cemeteries are part of the cultural heritage of urban communities, containing funerary crypts and monuments of historical and architectural interest. Efforts aimed at the conservation of these structures must target not only the abiotic stresses that ...

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

open access: yesEnvironmental 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

open access: yesEnvironmental 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 ...

The fox Operon from Rhodobacter Strain SW2 Promotes Phototrophic Fe(II) Oxidation in Rhodobacter capsulatus SB1003 [PDF]

open access: yes, 2007
Anoxygenic photosynthesis based on Fe(II) is thought to be one of the most ancient forms of metabolism and is hypothesized to represent a transition step in the evolution of oxygenic photosynthesis.

Genes and pathways for CO2 fixation in the obligate, chemolithoautotrophic acidophile, Acidithiobacillus ferrooxidans, Carbon fixation in A. ferrooxidans [PDF]

open access: yes, 2010
Background: Acidithiobacillus ferrooxidans is chemolithoautotrophic gamma-proteobacterium that thrives at extremely low pH (pH 1-2). Although a substantial amount of information is available regarding CO2 uptake and fixation in a variety of facultative ...

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

open access: yesEnvironmental 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.

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

open access: yesJournal 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 ...

Deep subsurface microbial life in impact‐altered Late Paleozoic granitoid rocks from the Chicxulub impact crater

open access: yesGeobiology, Volume 22, Issue 1, January/February 2024.
Abstract In 2016, IODP‐ICDP Expedition 364 recovered an 829‐meter‐long core within the peak ring of the Chicxulub impact crater (Yucatán, Mexico), allowing us to investigate the post‐impact recovery of the heat‐sterilized deep continental microbial biosphere at the impact site.
