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 ...

Accumulation of denitrification intermediates was observed in both the propionate- and H(2)/CO(2)-fed cultures, which resulted in inhibition of fermentation and ...

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 dietary nitrate level on enteric methane production ...

Methane production showed less fluctuation throughout the day with the high nitrate treatment compared with the control treatment. The disappearance of ...

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 ...

Studies have suggested that nitrate- and nitrite-reducing microbes compete with methanogen for hydrogen in the rumen, making nitrate an ...

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 ...

Effects of nitrate on methane production, fermentation, and microbial ...

Methane production was reduced by 70% at 12 μmol ml(-1) and nearly completely at ≥24 μmol ml(-1) nitrate. Production of volatile fatty acids (VFAs) was affected ...

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 on Methane Production and Fermentation by ...

Most probable number counts showed that denitrifying species were the numerically predominant NO− 3 reducing bacteria in the faeces of five methanogenic ...

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.

Combined effects of nitrate and medium-chain fatty acids on ... - Nature

Combined effects of nitrate and medium-chain fatty acids on methane production, rumen fermentation, and rumen bacterial populations in vitro.

Effect of Nitrate on Methane Production and Fermentation by ...

H2 as an electron donor for NO3 reduction. Washed faecal bacterial cell suspensions were prepared from faeces obtained from two individuals in anaerobic 0-1 M- ...

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 ...

Ruminal Fermentation of Anti-Methanogenic Nitrate - Frontiers

Presently, we found that nitrate-, NPA-, or NPOH-containing forages effectively decreased methane production, by 35–87%, during in vitro fermentation by mixed ...
