- Rock Hosted Microbial Communities
The Rock-Hosted Communities (RHC) grant sought to provide baseline data related to the distribution and function of microbial communities in rocky subsurface habitats underlying the continents and oceans. The grant served to link both field and experimental studies of rock-hosted microbial communities, with a particular focus upon the metabolism of carbon compounds. Application of molecular biological approaches, utilizing next-generation sequencing technology, provided a foundation to understand the potential, the diversity, and the evolution of metabolic pathways. These surveys were linked to the physiological characterization of novel cultivars, particularly at high pressure, and to activity measurements using stable isotope tracer approaches. These activities were coordinated across participating laboratories through face-to-face meetings, virtual meetings, and research exchanges.
