Formate-Dependent Heterodisulfide Reduction in a Methanomicrobiales Archaeon.
TL;DR: In an effort to better understand electron flow in methanogens from the order Methanomicrobiales, a genetic and biochemical study of heterodisulfide reductase (Hdr) in Methanoculleus thermophilus was conducted in this paper.

TL;DR: In this paper, a two-chamber bioelectrochemical cell equipped with a hybrid skirt-shaped cathode was constructed and the electrocatalytic performance of EAB and the electron shuttling mechanisms involved in extracellular electron transfer (EET) were systematically studied.

TL;DR: It is shown that in water, raw iron will transfer electrons from H2 to ferredoxin, uncovering a missing link in early metabolic evolution.

High-rate conversion of lactic acid-rich streams to caproic acid in a fermentative granular system.
TL;DR: This paper investigated varying glucose-to-lactate ratios and observed that decreasing glucose-content eliminated odd-chain by-products, while glucose omission required acetic acid addition to support lactic acid conversion.

Double-Cubane [8Fe9S] Clusters: A Novel Nitrogenase-Related Cofactor in Biology.
TL;DR: A new cofactor in the latter enzyme family is found, a double‐cubane cluster with two [4Fe4S] subclusters bridged by a sulfido ligand that catalyzes the ATP‐dependent reduction of small molecules, including acetylene.

Methanogenic archaea: ecologically relevant differences in energy conservation.
TL;DR: In methanogens with cytochromes, the first and last steps in methanogenesis from CO2 are coupled chemiosmotically, whereas in methenogens without cyto Chromes, these steps are energetically coupled by a cytoplasmic enzyme complex that mediates flavin-based electron bifurcation.

X-ray crystal structure of the Fe-only hydrogenase (CpI) from Clostridium pasteurianum to 1.8 angstrom resolution.
TL;DR: A three-dimensional structure for the monomeric iron-containing hydrogenase (CpI) from Clostridium pasteurianum was determined, providing insights into the mechanism of biological hydrogen activation and has broader implications for [Fe-S] cluster structure and function in biological systems.
