Mixed-valent iron [Fe (II)-Fe (III)] minerals such as magnetite and green rust have received a
significant amount of attention over recent decades, especially in the environmental …

Microbial fuel cells (MFCs) provide new opportunities for the sustainable production of
energy from biodegradable, reduced compounds. MFCs function on different carbohydrates …

Bacteria able to transfer electrons to metals are key agents in biogeochemical metal cycling,
subsurface bioremediation, and corrosion processes. More recently, these bacteria have …

The iron sulfides constitute a diverse group of solids and dissolved complexes many of
which play key roles in marine systems. The group is particularly complex in the lower …

ABSTRACT Dissimilatory Fe (III) and Mn (IV) reduction has an important influence on the
geochemistry of modern environments, and Fe (III)-reducing microorganisms, most notably …

Redox-driven biogeochemical element cycles play a central role in converting organic
matter in aquatic ecosystems. They also perform key functions such as removing nitrate …

Electroactive biofilms (EABFs) generated by electrochemically active microorganisms have
many potential applications in bioenergy and chemicals production. Biofilm electroactivity …

Microbial fuel cells hold great promise as a sustainable biotechnological solution to future
energy needs. Current efforts to improve the efficiency of such fuel cells are limited by the …

Clay minerals constitute an important component of the soil system and knowledge of their
role in soil fertility is imperative for sustainable soil management and productivity. The aim of …

Biochar naturally occurs in soils and sediments as a result of wildfire, but its role in Fe redox
cycling is poorly known. In this study, bioreduction experiments were conducted with lactate …
