Forage Level and Methane Inhibitor Effects on In Vitro Fermentation Products Using Forage Rape or Ryegrass as Substrates

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Dietary approaches that decrease ruminal pH may be combined with anti‐methanogenic feed additives that prevent methane formation and consequently increase the dissolved hydrogen concentration. To evaluate the effect of pH and the effect of dissolved hydrogen concentration, two forages (forage rape and ryegrass) were incubated in vitro at two forage ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 915-924, April 2026.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Uncovering the Diversity and Activity of Methylotrophic Methanogens in Freshwater Wetland Soils

mSystems, 2019
Wetland soils are one of the largest natural contributors to the emission of methane, a potent greenhouse gas. Currently, microbial contributions to methane emissions from these systems emphasize the roles of acetoclastic and hydrogenotrophic methanogens,

Inoculum selection influences the biochemical methane potential of agro-industrial substrates [PDF]

, 2015
Obtaining a reliable estimation of the methane potential of organic waste streams in anaerobic digestion, for which a biochemical methane potential (BMP) test is often used, is of high importance.

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

NanoFe3O4 as Solid Electron Shuttles to Accelerate Acetotrophic Methanogenesis by Methanosarcina barkeri

Frontiers in Microbiology, 2019
Magnetite nanoparticles (nanoFe3O4) have been reported to facilitate direct interspecies electron transfer (DIET) between syntrophic bacteria and methanogens thereby improving syntrophic methanogenesis.

Multi‐Omic Insights Into Mediterranean Diet‐Associated Microbiota

Molecular Nutrition &Food Research, Volume 70, Issue 7, 15 April 2026.
Mediterranean diet (MD) influences the composition of the gut mycobiome. Key foods of MD are related to bacterial and fungal composition. Combining metagenomics and metatranscriptomics tracks the gene expression profiles of gut microbiota. Metatranscriptomics identifies the transcriptionally active members of the microbiota that overexpressed genes ...
