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

From Plant to Paddy—How Rice Root Iron Plaque Can Affect the Paddy Field Iron Cycling
Soil Systems, 2020 Iron plaque on rice roots represents a sink and source of iron in paddy fields. However, the extent of iron plaque in impacting paddy field iron cycling is not yet fully deciphered.

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

Iron mineral dissolution releases iron and associated organic carbon during permafrost thaw
Nature Communications, 2020 Iron minerals trap carbon in permafrost, preventing microbial degradation and release to the atmosphere as CO2, but the stability of this carbon as permafrost thaws is unclear.
