1.
Lauzon J, Caron D, Lazar C
Microorganisms
. 2024 Sep;
12(9).
PMID: 39338466
The terrestrial subsurface harbors unique microbial communities that play important biogeochemical roles and allow for studying a yet unknown fraction of the Earth's biodiversity. The Saint-Leonard cave in Montreal City...

Lazar C, Schwab V, Ueberschaar N, Pohnert G, Trumbore S, Kusel K
Front Microbiol
. 2023 Oct;
14:1252498.
PMID: 37901809
Microbial communities are key players in groundwater ecosystems. In this dark environment, heterotrophic microbes rely on biomass produced by the activity of lithoautotrophs or on the degradation of organic matter...

Gagnon J, Beauregard-Tousignant S, Marcil J, Lazar C
Genes (Basel)
. 2023 Aug;
14(8).
PMID: 37628582
The deep terrestrial subsurface, hundreds of meters to kilometers below the surface, is characterized by oligotrophic conditions, dark and often anoxic settings, with fluctuating pH, salinity, and water availability. Despite...
4.
Groult B, St-Jean V, Lazar C
Microorganisms
. 2023 Jul;
11(7).
PMID: 37512847
Aquifer systems are composed of water flowing from surface recharge areas, to the subsurface and back to the surface in discharge regions. Groundwater habitats harbor a large microbial biomass and...

Villeneuve K, Turcotte-Blais V, Lazar C
Microorganisms
. 2023 Jun;
11(6).
PMID: 37375028
Events of groundwater recharge are associated with changes in the composition of aquifer microbial communities but also abiotic conditions. Modification in the structure of the community can be the result...
6.
Villeneuve K, Violette M, Lazar C
Genes (Basel)
. 2023 Jan;
14(1).
PMID: 36672742
Groundwater recharge and discharge rates and zones are important hydrogeological characteristics of aquifer systems, yet their impact on the formation of both subterranean and surface microbiomes remains largely unknown. In...

Lazar C, Schmidt F, Elvert M, Heuer V, Hinrichs K, Teske A
Front Microbiol
. 2023 Jan;
13:1043414.
PMID: 36620052
Mud volcanoes transport deep fluidized sediment and their microbial communities and thus provide a window into the deep biosphere. However, mud volcanoes are commonly sampled at the surface and not...
8.
Groult B, Bredin P, Lazar C
Environ Microbiol
. 2022 Sep;
24(12):5898-5910.
PMID: 36135934
Aquifers are inhabited by microorganisms from the three major domains of life: Archaea, Eukaryotes and Bacteria. Although interest in the processes that govern the assembly of these microbial communities is...

DesRosiers A, Gassama N, Grosbois C, Lazar C
Genes (Basel)
. 2022 Aug;
13(8).
PMID: 36011326
In freshwater ecosystems, dynamic hydraulic events (floods or dam maintenance) lead to sediment resuspension and mixing with waters of different composition. Microbial communities living in the sediments play a major...

Lazar C, Lehmann R, Stoll W, Rosenberger J, Totsche K, Kusel K
Sci Total Environ
. 2019 May;
679:35-44.
PMID: 31078773
Terrestrial subsurface microbial communities are not restricted to the fluid-filled void system commonly targeted during groundwater sampling but are able to inhabit and dwell in rocks. However, compared to the...
