Similar Methanogenic Shift but Divergent Syntrophic Partners in Anaerobic Digesters Exposed to Direct versus Successive Ammonium Additions

open access: yesMicrobiology Spectrum, 2021
During anaerobic digestion (AD) of protein-rich wastewater, ammonium (NH4+) is released by amino acid degradation. High NH4+ concentrations disturb the AD microbiome balance, leading to process impairments.

Temperature, inocula and substrate: contrasting electroactive consortia, diversity and performance in microbial fuel cells [PDF]

open access: yes, 2018
The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and ...

Ethyl 2-(2-methyl-4-nitro-1H-imidazol-1-yl)acetate

open access: yesIUCrData, 2016
In the title compound, C8H11N3O4, the imidazole ring and the nitro group are nearly coplanar, with the largest deviation from the mean plane being 0.119 (2) Å. The mean plane through the acetate group is approximately perpendicular to the imidazole ring,

A New Strategy to Stabilize Oxytocin in Aqueous Solutions: I. The Effects of Divalent Metal Ions and Citrate Buffer [PDF]

open access: yes, 2011
In the current study, the effect of metal ions in combination with buffers (citrate, acetate, pH 4.5) on the stability of aqueous solutions of oxytocin was investigated.

Metabolic kinetics of pulmonary surfactant in newborn infants using endogenous stable isotope techniques

open access: yesJournal of Lipid Research, 2005
We compared kinetic indices of pulmonary surfactant metabolism in premature infants (n = 41) with respect to i) tracer ([1-13C1]acetate, [U-13C6]glucose, and [1,2,3,4-13C4] palmitate), ii) phospholipid (PL) pool (total PLs or disaturated PLs), or iii ...

In vitro degradation and gas production of glycerin generated in the biodiesel production chain

open access: yesActa Scientiarum: Animal Sciences, 2015
This study was realized to evaluate the production of gas and volatile fatty acids when glycerin was used to replace four forage species through the use of a semi-automated technique in vitro.

Infusion of an acidified ethanolic—dextrose solution enhances urinary ammonium excretion and increases acid resilience in non—mechanically ventilated acidotic rabbits

open access: yesFrontiers in Physiology, 2022
Hitherto, the rabbit has long been known to have a very poor tolerance to non—volatile acid. In this study, we tested the hypothesis that acid resilience in the acidotic rabbit can be increased by enhancing the plasma availability of a naturally ...
