Effects of nitrate, nitrite, NO and N 2 O on methanogenesis and other ...

Addition of 5 mM nitrite resulted in complete inhibition of methanogenesis for at least 24 days (Fig. 4). Nitrite was reduced via NO and N2O for 3–4 days after ...

Effects of nitrate, nitrite, NO and N2O on methanogenesis and other ...

Methanogenic activity did not resume until all electron acceptors were reduced and, as a consequence, H2 had reached the methanogenic threshold again. Thus ...

Effect of Nitrate Reduction on the Methanogenic Fermentation

It has been reported that nitrate and/or reduced N-oxides, such as nitrite (NO2-), nitric oxide (NO), and nitrous oxide (N2O), which are products of ...

Inhibitory effects of nitrate reduction on methanogenesis in the ...

The preferential utilization of different electron donors and their effects on the nitrate reduction and methanogenesis in a mixed, mesophilic (35 degrees ...

Interactions between methanogenic and nitrate reducing bacteria ...

The effect of nitrate addition on the anaerobic digestion of an industrial sulfate rich wastewater was investigated using batch cultures.

Nitrate decreases ruminal methane production with slight changes ...

Nitrate can effectively suppress methane production because its reduction is a more favourable pathway for the hydrogen sink than the reduction ...

Effects of nitrate dosing on methanogenic activity in a sulfide ...

It was found that methanogenesis could coexist with denitrification and sulfate reduction in sewers dosed with nitrate. However, methane ...

Effect of dietary nitrate level on enteric methane production ...

Stoichiometrically, the addition of 1 mol of nitrate will lower methane production with 1 mol, corresponding to a decline in methane production of 25.8 g or ...

Effect of Nitrate on Methanogenesis at Low Redox Potential

Methanogenesis was found to commence after the total reduction of nitrates (or nitrogen oxides). Thus, the inhibition of methanogenesis by nitrate is reversible ...

Nitrate and Inhibition of Ruminal Methanogenesis - Frontiers

It would be instructive to determine if nitrate or its reduction products influence methanogenesis from methylamines. If the main mode of action is disruption ...

Effect of Nitrate on Methanogenesis at Low Redox Potential

However, it was observed that cysteine enhanced methanogenesis for cultures not containing nitrate. These cultures produced more methane than those without ...

Nitrate decreases methane production also by ... - AMB Express

A combined addition of ammonia salt and nitrate did not show further inhibitory effect on methane production but accelerated nitrate removal.

Nitrate supplementation in cattle reduces ruminal methane emissions

Nitrate reduction is highly competitive with methanogenesis, because it takes hydrogen utilization away from the CO2 reduction to methane, which is then ...

Unraveling the mechanism of assimilatory nitrate reduction and ...

... reduction and methane ... nitrogen and oxygen kinetic isotope effects of nitrate reduction by periplasmic dissimilatory nitrate reductase.

Effect of Sodium Nitrate and Nitrate Reducing Bacteria on In vitro ...

Nitrate can serve as a terminal electron acceptor in place of carbon dioxide and inhibit methane emission in the rumen and nitrate reducing bacteria might help ...

Effect of ethanol on nitrate and nitrite reduction and methanogenesis ...

The addition of ethanol to cultures of mixed ruminal microbes stimulated nitrate reduction, and, to a greater extent, nitrite reduction, which ...

Effects of nitrate, nitrite, NO and N2O on methanogenesis and other ...

Denitrification has been shown to diminish methanogenesis via denitrifiers directly outcompeting methanogenic archaea [35,38,39]. Sulfate reducing bacteria do ...

Inhibitory effects of nitrate reduction on methanogenesis in the ...

Batch methanogenic cultures were fed with dextrin/peptone (D/P), propionate, acetate, and H2/CO2 at an initial COD of 500 mg/L and an initial nitrate ...
