DOI: 10.1128/msystems.00328-22
Abstract: This first comparative metagenomic study of serpentinite-hosted environments provides an objective framework to understand the functioning of these peculiar ecosystems. We showed a taxonomic similarity between the PBHF and other terrestrial serpentinite-hosted ecosystems. ABSTRACT Serpentinizing… read more here.

DOI: 10.3389/fmicb.2018.00102
Abstract: The Bay of Prony, South of New Caledonia, represents a unique serpentinite-hosted hydrothermal field due to its coastal situation. It harbors both submarine and intertidal active sites, discharging hydrogen- and methane-rich alkaline fluids of low… read more here.
