Radionuclide Geomicrobiology of the Deep Biosphere

open access: yes, 2011
This review summarizes research into interactions between microorganisms and radionuclides under conditions typical of a repository for high-level radioactive waste in deep hard rock environments at a depth of approximately 500 m.

Disguised as a Sulfate Reducer: Growth of the Deltaproteobacterium Desulfurivibrio alkaliphilus by Sulfide Oxidation with Nitrate

open access: yesmBio, 2017
This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium.

The Microbial Community and Functional Potential in the Midland Basin Reveal a Community Dominated by Both Thiosulfate and Sulfate-Reducing Microorganisms

open access: yesMicrobiology Spectrum, 2022
The Permian Basin is the highest producing oil and gas reservoir in the United States. Hydrocarbon resources in this region are often accessed by unconventional extraction methods, including horizontal drilling and hydraulic fracturing.

Photoactivated Signaling Networks using DNA‐Based Synthetic Organelles as Biomimetic Protocells

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Light‐triggered intercommunication between two types of organelle‐loaded liposomes lead to DNAzyme‐mediated on transcription‐guided structural reconfiguration of the organelles. ABSTRACT Membraneless organelles formed by phase‐separated nucleic acid or protein condensates play vital roles in regulating cellular functions.

Microbial turnover times in the deep seabed studied by amino acid racemization modelling

open access: yesScientific Reports, 2017
The study of active microbial populations in deep, energy-limited marine sediments has extended our knowledge of the limits of life on Earth. Typically, microbial activity in the deep biosphere is calculated by transport-reaction modelling of pore water ...

Metapangenomic investigation provides insight into niche differentiation of methanogenic populations from the subsurface serpentinizing environment, Samail Ophiolite, Oman

open access: yesFrontiers in Microbiology, 2023
Serpentinization reactions produce highly reduced waters that have hyperalkaline pH and that can have high concentrations of H2 and CH4. Putatively autotrophic methanogenic archaea have been identified in the subsurface waters of the Samail Ophiolite ...

N2O formation by nitrite-induced (chemo)denitrification in coastal marine sediment

open access: yesScientific Reports, 2019
Nitrous oxide (N2O) is a potent greenhouse gas that also contributes to stratospheric ozone depletion. Besides microbial denitrification, abiotic nitrite reduction by Fe(II) (chemodenitrification) has the potential to be an important source of N2O. Here,

Applications of Fourier-transform Infrared Spectroscopy in Geomicrobiology

open access: yes, 2019
Fourier-transform infrared (FTIR) spectroscopy is a technique that measures the molecular-level vibrations in a material, such as a bacterial biofilm, to get a better understanding of the chemistry of the system.
