Metabolic versatility in methanogens
Current Opinion in Biotechnology, 2014 Methanogenesis is an anaerobic metabolism responsible for the generation of >90% of the methane formed on Earth today, with important implications for fuels production and global warming. Although methanogenic Archaea have been cultured for over 70 years, key insights regarding electron flow and energy conservation in methanogenesis have only recently ...

Sedimentology, EarlyView.ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion [PDF]
, 2012 This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria
Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges
ChemBioEng Reviews, Volume 13, Issue 2, April 2026.This review examines underground hydrogen storage with emphasis on the interaction between surface facilities and subsurface reservoirs. Variable renewable hydrogen requires compression, buffering, and purification before injection, while subsurface processes influence wellhead pressure, temperature, and composition.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization
ChemBioEng Reviews, Volume 13, Issue 2, April 2026.The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Bacterial community analysis in upflow multilayer anaerobic reactor (UMAR) treating high-solids organic wastes [PDF]
, 2017 A novel anaerobic digestion configuration, the upflow multi-layer anaerobic reactor (UMAR), was developed to treat high-solids organic wastes. The UMAR was hypothesized to form multi-layer along depth due to the upflow plug flow; use of a recirculation ...

Methanogens, Methane and Gastrointestinal Motility
Journal of Neurogastroenterology and Motility, 2014 Anaerobic fermentation of the undigested polysaccharide fraction of carbohydrates produces hydrogen in the intestine which is the substrate for methane production by intestinal methanogens. Hydrogen and methane are excreted in the flatus and in breath giving the opportunity to indirectly measure their production using breath testing.
