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 …

Minerals and organic matter (OM) may form intricate associations via myriad interactions. In
soils, the associations of OM with mineral surfaces are mainly investigated because of their …

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 …

Biochar influences soil fertility, N2O emissions, and atmospheric CO2 budgets, and because
of its quinone and aromatic structures, it is redox-active. Here we demonstrate that biochar …

Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

Humic substances form through the degradation of microbial and plant precursors, and
make up a significant fraction of natural organic matter in terrestrial and aquatic …

Owing to the development of urbanization, the amount of sewage sludge generated through
biological activated sludge process has increased dramatically. Anaerobic fermentation of …

The state of the art of the reported data on interactions between microorganisms and HSs is
presented herein. The properties of HSs are discussed in terms of microbial utilization …

The presence of arsenic in the groundwater of the densely-populated Bengal Basin evolved
as a mass-poisoning agent and is a reason for the misery of millions of people living here …

During the last two decades, extensive research has explored the catalytic effects of different
organic molecules with redox mediating properties on the anaerobic (bio) transformation of …
