Soils and sediments are major reservoirs of organic matter (OM), whose dynamic turnover
has a major impact on carbon cycling and global climate. OM in soils and sediments is …

Mineral–microbe interactions play important roles in environmental change, biogeochemical
cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical …

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 …

Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

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 …

Microbial reduction under anaerobic condition is a promising method for remediating
vanadate [V (V)] contamination in aquifers, while V (V) may be re-generated with redox …

Nitrogen removal through microorganisms is the most important pathway in constructed
wetlands (CWs). In this review, we summarize the microbial coupling mechanisms of …

Manganese oxide (MnOx) mediated ammonium (NH 4+) oxidation in wetlands is receiving
increased interest; however, the biochemical mechanisms of this process are vague due to …

Cadmium (Cd) contamination of soils is a global problem, particularly in paddy soils. Fe
oxides, as a key fraction of paddy soils, can significantly affect the environmental behavior of …

Two records of Earth history capture the evolution of life and its co-evolving ecosystems with
interpretable fidelity: the geobiological and geochemical traces preserved in rocks and the …
