Abstract Background The Black Sea is the largest brackish water body in the world, although
it is connected to the Mediterranean Sea and presents an upper water layer similar to some …

Viruses as the prevailing biological entities are poorly understood in underground realms.
Here, we establish the first metagenomic Groundwater Virome Catalogue (GWVC) …

Acid mine drainage (AMD) is a worldwide environmental problem, yet bioremediation is
hampered by a limited knowledge of the reductive microbial processes in the AMD …

The biology of Korarchaeia remains elusive due to the lack of genome representatives.
Here, we reconstruct 10 closely related metagenome-assembled genomes from hot spring …

Bacterial cooperation is very important for anammox bacteria which perform low-carbon and
energy-efficient nitrogen removal, yet its variation to adapt to high NH 4+-N concentration in …

The archaeal superphylum DPANN (an acronym formed from the initials of the first five phyla
discovered: Diapherotrites, Parvarchaeota, Aenigmarchaeota, Nanohaloarchaeota and …

The migration of geogenic gases in continental areas with geothermal activity and active
faults is an important process releasing greenhouse gases (GHG) to the lower troposphere …

Terrestrial geothermal springs are physicochemically diverse and host abundant
populations of Archaea. However, the diversity, functionality, and geological influences of …

Groundwater recharge and discharge rates and zones are important hydrogeological
characteristics of aquifer systems, yet their impact on the formation of both subterranean and …

Members of the phylum “Candidatus Nanohaloarchaeota,” a representative lineage within
the DPANN superphylum, are characterized by their nanosized cells and symbiotic lifestyle …
