Sampling and genomic efforts over the past decade have revealed an enormous quantity
and diversity of life in Earth's extreme environments. This new knowledge of life on Earth …

Around 50% of humankind relies on groundwater as a source of drinking water. Here we
investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 …

Owing to their roles in the arsenic (As) biogeochemical cycle, microorganisms and plants
offer significant potential for develo** innovative biotechnological applications able to …

The current classification of the phylum Firmicutes (new name, Bacillota) features eight
distinct classes, six of which include known spore-forming bacteria. In Bacillus subtilis …

The performance of a permeable reactive barrier (PRB) for the in situ remediation of
hexavalent chromium [Cr (VI)] contaminated groundwater, and the resulted responses in the …

We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks
between subspecies and class, proposed between the mid-1990s, when the provisional …

To get insights into microbial diversity and biogeochemical processes in the terrestrial deep
subsurface aquifer, we sequenced the metagenome of artesian water collected at a 2.8 km …

Subsurface environments are among Earth's largest habitats for microbial life. Yet, until
recently, we lacked adequate data to accurately differentiate between globally distributed …

Serpentinization of ultramafic rocks provides molecular hydrogen (H2) that can support
lithotrophic metabolism of microorganisms, but also poses extremely challenging conditions …

There is still a lack of understanding of H2S formation in agricultural waste, which leads to
poor odour prevention and control. Microbial sulfate reduction is a major process …
