TLDR
In this paper, the effect of temperature in the range of 40-64°C on thermophilic anaerobic digestion of cattle manure with two different ammonia concentrations (2.5 and 6.0 g-N/l) was investigated in continuouslyfed lab-scale reactors: the higher ammonia concentration reduced the maximum tolerable temperature.About:

Journal ArticleDOI
Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.
Journal ArticleDOI
Anaerobic digestion of microalgae as a necessary step to make microalgal biodiesel sustainable.
TL;DR: The ability of these CO2 consuming microalgae to purify biogas and concentrate methane is discussed, and anaerobic digestion of the whole biomass appears to be the optimal strategy on an energy balance basis for the energetic recovery of cell biomass.

Anaerobic digestion of swine manure: Inhibition by ammonia
TL;DR: A stable anaerobic degradation of swine manure with ammonia concentration of 6 g-N/litre was obtained in continuously stirred tank reactors with a hydraulic retention time of 15 days, at four different temperatures as discussed by the authors.

Ammonia inhibition in anaerobic digestion: A review
Orhan Yenigun,Burak Demirel +1 more
TL;DR: Ammonia inhibition in anaerobic digestion systems and the recovery efforts after inhibition are discussed and the impacts of ammonia inhibition on the microbial population available in an aerobic digesters, namely bacteria and Archaea are evaluated in detail.
Journal ArticleDOI
A critical review on inhibition of anaerobic digestion process by excess ammonia.
TL;DR: It is emphasized that more profound knowledge on parameters influencing ammonia-inhibition is needed to apply appropriate control strategies to ensure a stable and undisturbed digestion of anaerobic digestion of N-rich organic-feedstock.

Effects of lipids on thermophilic anaerobic digestion and reduction of lipid inhibition upon addition of bentonite.
TL;DR: The effect of bentonite-bound oil on thermophilic anaerobic digestion of cattle manure was investigated and very rapid degradation of oil was observed and more than 80% of the oil was degraded within a few hours after daily feeding.

Influence of high NaCl and NH4Cl salt levels on methanogenic associations
TL;DR: The methanogenic associations, grown on a medium containing mainly acetate and ethanol, were found to be more resistant to NaCl and NH 4 Cl than previously reported.
