Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments. [PDF]

Environ Microbiol Rep
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.
