Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Many iron (Fe) redox processes that were previously assumed to be purely abiotic, such as
photochemical Fe reactions, are now known to also be microbially mediated. Owing to this …

Sedimentary rocks deposited across the Proterozoic–Phanerozoic transition record extreme
climate fluctuations, a potential rise in atmospheric oxygen or re-organization of the seafloor …

The addition of iron is a convenient way for removing phosphorus from wastewater, but this
is often considered to limit phosphorus recovery. Struvite precipitation is currently used to …

Almost the entire seafloor is covered with sediments that can be more than 10 000 m thick
and represent a vast microbial ecosystem that is a major component of Earth's element and …

Reduction–oxidation (redox) reactions occur during burial because sediments contain
reactive mixtures of oxidised and reduced components. Diagenetic chemical reactions …

Molecular oxygen (O2) is, and has been, a primary driver of biological evolution and shapes
the contemporary landscape of Earth's biogeochemical cycles. Although “whiffs” of oxygen …

Phosphate recovery from sewage sludge is essential in a circular economy. Currently, the
main focus in centralized municipal wastewater treatment plants (MWTPs) lies on struvite …
