The use of direct-fed microbials for mitigation of ruminant methane emissions: a review
Animal, 2014 Concerns about the environmental effect and the economic burden of methane (CH4) emissions from ruminants are driving the search for ways to mitigate rumen methanogenesis.

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Response of methane emissions, redox potential, and pH to eucalyptus biochar and rice straw addition in a paddy soil [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 This study aims to comprehend the links between soil Eh and pH changes in eucalyptus biochar (BC) and rice straw (RS) amended soils and CH4 emissions. Increased CH4 emission rates and high total CH4 emissions (TCH4 ) were found in RS soils.

Transformation of 1,1,1-trichloroethane in an anaerobic packed-bed reactor at various concentrations of 1,1,1-trichloroethane, acetate and sulfate [PDF]
, 1997 Biotransformation of 1,1,1-trichloroethane (CH3CCl3) was observed in an anaerobic packed-bed reactor under conditions of both sulfate reduction and methanogenesis. Acetate (1 mM) served as an electron donor.

Structural Basis of Hydrogenotrophic Methanogenesis
Annual Review of Microbiology, 2020 Most methanogenic archaea use the rudimentary hydrogenotrophic pathway—from CO2and H2to methane—as the terminal step of microbial biomass degradation in anoxic habitats. The barely exergonic process that just conserves sufficient energy for a modest lifestyle involves chemically challenging reactions catalyzed by complex enzyme machineries with unique ...

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,

Rice response as affected by various fertilizer‐P sources under contrasting irrigation methods
Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.Abstract Alternative fertilizer‐phosphorus (P) sources created by recycling excess nutrients from waste sources, such as struvite (MgNH4PO4·6H2O), require further research to determine their niche in agriculture and potential environmental implications.
