Augmenting Biogas Process Modeling by Resolving Intracellular Metabolic Activity [PDF]

, 2019
The process of anaerobic digestion in which waste biomass is transformed to methane by complex microbial communities has been modeled for more than 16 years by parametric gray box approaches that simplify process biology and do not resolve intracellular ...

Low methane emissions from nutrient‐rich former river channels in a hydrologically managed dryland delta

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Anthropogenic stresses in dryland regions can alter hydrology, salinization, and biogeochemical processes. How these pressures influence methane (CH4) cycling and emissions from aquatic ecosystems remains poorly understood. Over the course of 1 year, we measured diffusive and ebullitive CH4 emissions from resacas—shallow, hydrologically ...

Competition of electrogens with methanogens for hydrogen in bioanodes.

Water Research, 2019
Bioelectrochemical systems (BES) can provide an energy efficient way to recover nutrients from wastewaters. However, the electron donors available in wastewater are often not sufficient to recover the total amount of nutrients.

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 ...

Methanonatronarchaeum thermophilum gen. nov., sp. nov. and 'Candidatus Methanohalarchaeum thermophilum', extremely halo(natrono)philic methyl-reducing methanogens from hypersaline lakes comprising a new euryarchaeal class Methanonatronarchaeia classis nov.

International Journal of Systematic and Evolutionary Microbiology, 2018
Methanogenic enrichments from hypersaline lakes at moderate thermophilic conditions have resulted in the cultivation of an unknown deep lineage of euryarchaeota related to the class Halobacteria.

Effects of Diet Composition and Yeast Cell Wall Supplementation on Ruminal Fermentation, Gas Kinetics, Methane Production and Digestibility Assessed In Vitro Using Gas Production and DaisyII Incubator Systems

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study evaluated the effects of yeast cell wall (YCW) supplementation in diets with varying roughage‐to‐concentrate (R:C) ratios using in vitro techniques. The results demonstrated that YCW supplementation significantly reduced total gas and methane production, particularly in high‐roughage diets, without compromising dry matter digestibility or ...

Are Insects a Feasible Option or Just a Hyped Promise in Ruminant Nutrition? A Systematic Review of What Has Been Done and What Lies Ahead

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Insects are emerging as sustainable alternatives for ruminants. This systematic review evaluates in vitro and in vivo evidence on insect‐based feeds in ruminant nutrition, discussing their outcomes and elucidating underlying mechanisms. Despite promising effects on rumen fermentation, growth, and product quality, inconsistencies related to insect ...

Methanogens Through Time and Space: Impact on Earth’s Planetary Evolution and Biogeochemistry

Geosciences
Methanogens, or methanogenic archaea (MA), are among the most ancient and widely distributed microorganisms, characterized by a unique metabolism that generates methane (CH4) as the terminal product of anaerobic respiration.

White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the
