The role of deeply buried microbes is far more important than has been previously presumed. Comprehensive studies of deep subsurface microbiology have revealed not only cell abundances that match previous estimates in surface environments, but most importantly, have demonstrated the viability of these microbes and their essential roles in operating and maintaining global biogeochemical cycles. The deep subsurface biosphere refers to the vast ecosystems of microorganisms that exist within marine subseafloor sediments and the oceanic crust, as well as continental subterranean environments. They are estimated to contain a significant portion of the total biomass on Earth and are comprised of diverse microbial taxa including bacteria, archaea, protists, and fungi that survive in environments that are often extremely energy-limited. Due to the unique characteristics of these ecosystems, deep subsurface microorganisms are often distinct from those found in surface environments and laboratory strains. They are becoming a crucial topic of research for their unusual adaptations to energy limitation and their important interactions with the geosphere. Despite its size and significance, however, the deep biosphere remains largely understudied. One of the main gaps in our knowledge is the extent of microbial biogeochemical activity across the physicochemical gradients that characterize deep biosphere extreme ecosystems. This is due, in large part, to the high uncertainty in metabolic rate estimates and unknown systematic biases due to data scarcity. Bioenergetic studies have provided a conceptual framework for understanding the complexity of microbial metabolism within various spatial and temporal scales. However, our knowledge of energy metabolism in the deep biosphere is hindered by inadequate methodology for energy flux quantification and incomplete data of the actual energy parameters associated with subsurface microbes, many of which are novel and uncharacterized species. Despite these gaps, research on the deep biosphere continues to provide new insights into the function of these unique microbial communities and their potential to reach and impact the chemical economy of the overlying ecosystems. The aim of this Research Topic is to open a new perspective on the biotic/abiotic interface in extreme microbiology. We invite contributions from scientists working in diverse disciplines who have a common interest in various aspects of the study of microorganisms that live in energy-limited deep subsurface environments. This can include research on the diversity, activity, genetic repertoire, and expression of subsurface microbial communities and their resulting biogeochemical activity. We encourage the submission of manuscripts focusing on recent advances in deep biosphere studies by using both empirical and theoretical approaches. Articles in this Research Topic are dedicated to commemorating the late Jan Amend, whose pioneering work significantly advanced our understanding of microbial life in deep subsurface environments. Amend's contributions not only challenged existing notions about the limits of life but also provided key insights into the survival strategies of microbes in energy-limited settings, continuing to inspire and guide current research in extreme microbiology.

Deep subsurface microbiology is a highly active and rapidly advancing research field at the interface of microbiology and the geosciences; it focuses on the detection, identification, quantification, cultivation and activity measurements of bacteria, archaea and eukaryotes that permeate the subsurface biosphere of deep marine sediments and the basaltic ocean and continental crust. 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.

In collaboration with Microenergy 2022: The 4th International Workshop on Microbial Life under Extreme Energy Limitation, we are proud to launch Volume II of Studies on Life at the Energetic Edge – from Laboratory Experiments to Field-Based Investigations. This workshop focuses on the energy controls on microbial life and the exploration of the biological demand for energy. Genetic adaptations and phenotypic traits that enable microorganisms to tolerate long periods of energy limitation have attracted broad scientific interest in recent years. Laboratory-based cultivation experiments have shown that the potential to survive weeks to months in the absence of energy inputs occurs across a phylogenetically wide range of microbes. Studies on natural environments have shown that energy limitation is pervasive across most habitats on Earth, from highly metabolically active surface habitats to subsurface environments that have been cut off from new energy inputs for thousands of years. Yet, much remains to be learned about the evolutionary adaptations and life history traits that enable microorganisms to live under low-energy conditions. Similarly, the spectrum of energy sources and metabolisms that enable and support life on Earth and potentially elsewhere in the Universe is far from constrained.

Seafloor fluid and gas emission has been revealed to be a geographically widespread phenomenon in recent years as researchers have discovered new off-axis hydrothermal vent fields and previously unmapped shallow (deltaic, continental shelf) and deep water cold seeps. Seafloor seep emissions play a critical role in global biogeochemical cycles, but also contribute to the development of economically important mineral deposits that are increasingly targeted for exploitation. Hydrothermal vents and cold seeps host unique microbiological and macrofaunal communities that provide clues to life on primordial Earth, and seafloor fluid and gas emissions play a complex role in microbial dispersal, ocean chemistry, plankton dynamics, and possibly global climate. This Research Topic will address the knowledge gaps about the linked chemistry, macro/microbiology, physics, and geology of seafloor emissions and explore both the economic potential and conservation efforts associated with hydrothermal vents and cold seeps.
