Wastewater treatment plants face significant challenges in transitioning from energy-
intensive systems to carbon-neutral, energy-saving systems, and a large amount of chemical …

Abstract Microbial vanadate [V (V)] reduction is the key process of vanadium geochemical
cycling, while the identified functional microbes are rather limited. Considering the structural …

Phosphorus (P) and iron (Fe) are two essential mineral nutrients in plant growth. It is widely
observed that interactions of P and Fe could influence their availability in soils and affect …

Microorganisms in wetland groundwater play an essential role in driving global
biogeochemical cycles. However, largely due to the dynamics of spatiotemporal surface …

Organic acid is prevalent in underground environments and, against the backdrop of
biogeochemical cycles on Earth, holds significant importance in the degradation of …

The redox activity of Fe-bearing minerals is coupled with the transformation of organic matter
(OM) in redox dynamic environments, but the underlying mechanism remains unclear. In this …

Electron transfer (ET) is the fundamental redox process of life and element cycling. The ET
distance is normally as short as nanometers or micrometers in the subsurface. However, the …

Soil organic carbon (SOC) is pivotal for both agricultural activities and climate change
mitigation, and biochar stands as a promising tool for bolstering SOC and curtailing soil …

Riparian zones are important depositional environments at the catchment scale and provide
environmental services such as carbon sequestration. This zone is a highly dynamic …

Carbonates represent major sedimentary rocks in on the continental and oceanic crust of
Earth and are often closely related to microbial activities. However, the origin of magnesium …
