Biogeochemistry is controlled by a small set of microbial-encoded proteins containing redox-
sensitive transition metals as their core catalytic centre. Understanding how the …

Biogeochemistry is at the dawn of an era in which molecular advances enable the discovery
of novel microorganisms having unforeseen metabolic capabilities, revealing new insight …

Life is based on energy gained by electron-transfer processes; these processes rely on
oxidoreductase enzymes, which often contain transition metals in their structures. The …

Microbial processes dominate geochemical cycles at and near the Earth's surface today.
Their role was even greater in the past, with microbes being the dominant life form for the …

The biogeochemical controls on metal behaviour in aqueous environments involve complex
linkages of biological, principally bacterially driven, and geochemical processes, which …

Throughout geologic time, a strong feedback has existed between the geosphere and the
biosphere; therefore biological evolution and innovation can be linked to the evolution of …

▪ Abstract Bacteria are remarkable in their metabolic diversity due to their ability to harvest
energy from myriad oxidation and reduction reactions. In some cases, their metabolisms …

We are becoming increasingly aware of the role played by archaea in the biogeochemical
cycling of the elements. Metabolism of metals is linked to fundamental metabolic functions …

Microbes play key geoactive roles in the biosphere particularly in the areas of element
biotransformations and biogeochemical cycling, metal and mineral transformations …

Metals, both toxic and valuable, are found in deposits of variable richness. Human activities
have dispersed metals beyond their natural deposits throughout soil, sediments, and …
