The deep subsurface biosphere abounds with uncultured, only recently discovered and ? at best - incompletely understood microbial populations. In spatial extent and volume, Earth?s subsurface biosphere is only rivaled by the deep sea water column. So far, no deep subsurface sediment has been found that is entirely devoid of microbial life; microbial cells and DNA remain detectable at sediment depths of more than 1 km; microbial life permeates deeply buried hydrocarbon reservoirs, and is also found several kilometers down in continental crust aquifers. Severe energy limitation, either as electron acceptor or donor shortage, and scarcity of microbially degradable organic carbon sources are among the evolutionary pressures that have shaped the genomic and physiological repertoire of the deep subsurface biosphere. Its biogeochemical role as long-term organic carbon repository, inorganic electron and energy source, and subduction recycling engine continues to be explored by current research at the interface of microbiology, geochemistry and biosphere/geosphere evolution. This Research Topic addresses some of the central research questions about deep subsurface microbiology and biogeochemistry: phylogenetic and physiological microbial diversity in the deep subsurface; microbial activity and survival strategies in severely energy-limited subsurface habitats; microbial activity as reflected in process rates and gene expression patterns; biogeographic isolation and connectivity in deep subsurface microbial communities; the ecological standing of subsurface biospheres in comparison to the surface biosphere ? an independently flourishing biosphere, or mere survivors that tolerate burial (along with organic carbon compounds), or a combination of both? Advancing these questions on Earth?s deep subsurface biosphere redefines the habitat range, environmental tolerance, activity and diversity of microbial life. 606 $aMicrobiology & Immunology$2HILCC 606 $aBiology$2HILCC 606 $aHealth & Biological Sciences$2HILCC 610 $amarine sediment 610 $aMethane 610 $adeep biosphere 610 $aacetogenesis 610 $asubseafloor sediment 610 $aHydrogen 610 $adeep subsurface 610 $aocean crust 610 $asulfate reduction 610 $aPeru margin 615 7$aMicrobiology & Immunology 615 7$aBiology 615 7$aHealth & Biological Sciences 700 $aAxel Schippers$4auth$01314141 702 $aBiddle$b Jennifer F 702 $aTeske$b Andreas 702 $aEdgcomb$b Virginia P 801 0$bPQKB 801 2$bUkMaJRU 912 $a9910137532203321 996 $aDeep subsurface microbiology$93387156 997 $aUNINA
