Conductive materials (CM) have been extensively reported to enhance methane production
in anaerobic digestion processes. The occurrence of direct interspecies electron transfer …

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 …

Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Methane fermentation is an attractive practice in waste processing, which enables one to
both control pollution and recover energy. This kind of anaerobic digestion is exposed to …

Interactions between microorganisms and clay minerals are ubiquitous in nature and are
involved in the formation and transformation of clay minerals and the global cycles of many …

Vanadium (V) is an emerging contaminant in groundwater that can adversely affect human
health. Although bioremediation has been shown effective, little is known on autotrophic V …

Extracellular electron exchange in Methanosarcina species and closely related Archaea
plays an important role in the global carbon cycle and enhances the speed and stability of …

Anaerobic digestion (AD) is a well-established technology used for the treatment of wastes
and wastewaters with high organic content. During AD organic matter is converted stepwise …

Anaerobic methane oxidation in archaea is often presented to operate via a pathway of
“reverse methanogenesis”. However, if the cumulative reactions of a methanogen are run in …

Clay minerals are ubiquitous in soils, sediments, and sedimentary rocks, and they play
important roles in environmental processes. Microbes are also abundant in these geological …
