Rumen methanogens, and inhibition of methanogenesis
Australian Journal of Agricultural Research, 1999Methane-producing archaea (known as methanogens) are a distinct group of organisms which are a normal component of the rumen microbial ecosystem. Hydrogen and carbon dioxide are the principal substrates used by rumen methanogens to produce methane (CH4).

Attempts to inhibit ruminal methanogenesis by blocking pyruvate oxidative decarboxylation
Canadian Journal of Microbiology, 2003The inhibition of pyruvate oxidative decarboxylation as a means of decreasing ruminal methanogenesis in vitro was studied. In the first experiment, the addition of adenosine and adenine (with and without ribose) to ruminal batch cultures did not decrease methanogenesis. In the second experiment, the addition of oxythiamin decreased methanogenesis by 23%

Dietary supplementation with mulberry leaf flavonoids inhibits methanogenesis in sheep
Animal Science Journal, 2016AbstractThe effects of flavonoids on methanogenesis and microbial flora in Dorper × thin‐tailed Han crossbred ewes were evaluated in two experiments. To investigate the effects of flavonoids on nutrient digestibility and nitrogen balance, 18 ewes (60.0 ± 1.73 kg body weight (BW)) were allotted to two dietary treatments in experiment one, a control diet

The kinetics of process dependent ammonia inhibition of methanogenesis from acetic acid
Water Research, 2012Advanced anaerobic digestion processes aimed at improving the methanization of sewage sludge may be potentially impaired by the production of inhibitory compounds (e.g. free ammonia). The result of methanogenic inhibition is relatively high effluent concentrations of acetic acid and other soluble organics, as well as reduced methane yields.

Inhibition of methanogenesis by sulphate reducing bacteria competing for transferred hydrogen
Archives of Microbiology, 1978A methanogenic bacterial consortium was obtained after inoculation of benzoate medium under N2/CO2 atmosphere with intertidal sediment. A hydrogen donating organotroph and Methanococcus mazei were isolated from this enrichment. H2-utilising sulphate reducing bacteria were isolated under H2/CO2 in the absence of organic electron donors.

The effect of aromatic structure on the inhibition of acetoclastic methanogenesis in granular sludge
Applied Microbiology and Biotechnology, 1991Benzene derivatives are important constituents of certain effluents discharged by pulp and paper, petrochemical and chemical industries. The anaerobic treatment of these waste-waters can be limited due to methanogenic inhibition exerted by aromatic compounds.

Inhibition of methanogenesis from acetate by Cr+3 and ammonia
Biotechnology Letters, 19944000 mg/l of N−NH4 + and 12 mg/l or Cr+3 caused a 50% reduction in aceticlastic methanogenic activity of an anaerobic sludge.Methanosarcina-like andMethanothrix-like cells were differently affected by the toxicants. The inhibition caused by Cr+3 was reverted by its removal, by addition of iron and by increasing the biomass.

Ammonia inhibition of methanogenesis from cattle wastes
Agricultural Wastes, 1986Ammonia inhibition of methanogenesis from cattle wastes was studied using laboratory scale, mesophilic and thermophilic fermentors fed beef-catle manure (40 kg Volatile Solids per cubic metre) and various levels of 5N NH4Cl. Results showed that ammonia inhibition began at about 2·5 kg Nm−3 for both thermophilic and mesophilic fermentations that were ...

Experimental Burial Inhibits Methanogenesis and Anaerobic Decomposition in Water-Saturated Peats
Environmental Science & Technology, 2011A mechanistic understanding of carbon (C) sequestration and methane (CH(4)) production is of great interest due to the importance of these processes for the global C budget. Here we demonstrate experimentally, by means of column experiments, that burial of water saturated, anoxic bog peat leads to inactivation of anaerobic respiration and ...
