Iron and sulfide oxidation within the basaltic ocean crust: implications for chemolithoautotrophic microbial biomass production
Wolfgang Bach,Katrina J. Edwards +1 more
TLDR
In this article, the authors assess the oxidation state of altered ocean crust and estimate the magnitude of microbial biomass production that might be supported by oxidative and nonoxidative alteration, and estimate that 50% of Fe oxidation may be attributed to hydrolysis, producing 4.5 ± 3.0 × 1011 mol H2/yr.About:

TL;DR: Diverse microbial communities and numerous energy-yielding activities occur in deeply buried sediments of the eastern Pacific Ocean and these sedimentary communities may supply dissolved electron donors and nutrients to the underlying crustal biosphere.
Journal ArticleDOI
Microbial Ecology of the Dark Ocean above, at, and below the Seafloor
TL;DR: This review focuses on the current understanding of microbiology in the dark ocean, outlining salient features of various habitats and discussing known and still unexplored types of microbial metabolism and their consequences in global biogeochemical cycling.
Journal ArticleDOI
Feast and famine - microbial life in the deep-sea bed.
TL;DR: Microbial biodiversity and function in these intriguing environments, where energy is most depleted, might even be based on the cleavage of water by natural radioisotopes, are reviewed.
Journal ArticleDOI
Beyond the Calvin cycle: autotrophic carbon fixation in the ocean.
Michael Hügler,Stefan M. Sievert +1 more
TL;DR: Recent discoveries in the field of autotrophic carbon fixation are reviewed, including the biochemistry and evolution of the different pathways, as well as their ecological relevance in various oceanic ecosystems.
Journal ArticleDOI
Prokaryotic cells of the deep sub-seafloor biosphere identified as living bacteria
Axel Schippers,Lev N. Neretin,Jens Kallmeyer,Timothy G. Ferdelman,Barry Andrew Cragg,Ronald John Parkes,Bo Barker Jørgensen +6 more
TL;DR: It is shown that a large fraction of the sub-seafloor prokaryotes is alive, even in very old (16 million yr) and deep (> 400 m) sediments.

Revised calibration of the geomagnetic polarity timescale for the Late Cretaceous and Cenozoic
Steven C. Cande,Dennis V. Kent +1 more
TL;DR: An adjusted geomagnetic reversal chronology for the Late Cretaceous and Cenozoic is presented that is consistent with astrochronology in the Pleistocene and Pliocene and with a new timescale for the Mesozoic.
Journal ArticleDOI
Energetics of syntrophic cooperation in methanogenic degradation.
TL;DR: S syntrophically fermenting bacteria synthesize ATP by substrate-level phosphorylation and reinvest part of the ATP-bound energy into reversed electron transport processes, to release the electrons at a redox level accessible by the partner bacteria and to balance their energy budget.
