Zero-valent iron (ZVI) is known to be an additive in facilitating waste treatment and improving
biogas production in anaerobic digestion (AD) systems. This review concentrates on the …

Alkaliphiles are interesting groups of extremophilic organisms that thrive at pH of 9.0 and
above. Many of their products, in particular enzymes, have found widespread applications in …

Anaerobic digestion (AD) is a promising method to treat organic matter. However, AD
performance was limited by the inefficient electron transfer and metabolism imbalance …

The application of nanomaterials to contaminated river sediments could induce important
changes in the speciation of heavy metals with potential impacts on ecosystem. Here …

Iron reduction is an important biogeochemical process in paddy soils, yet little is known
about the microbial coupling between nitrogen and iron reduction. Here, we investigated the …

The role of iron-reducing bacteria (IRB) in biocorrosion is under discussion. According to
some reports, IRB are able to induce protection of carbon steel while others suggest an …

Acidimicrobiaceae sp. A6 (referred to as A6) was recently identified as playing a key role in
the Feammox process (ammonium oxidation coupled to iron reduction). Two constructed …

To address the issue that Fe 3+ precipitate would inhibit microbial metabolic activity, and to
further promote the total nitrogen removal efficiency (TNRE), polymeric ferric sulfate (PFS) …

The biochemical and molecular mechanisms used by alkaliphilic bacterial communities to
reduce metals in the environment are currently unknown. We demonstrate that an …

Sulfur reduction in freshwater ecosystems has previously been considered as negligible
because of often very low sulfate concentrations and generally low sulfate reducing capacity …
