Effect of a Profound Feedstock Change on the Structure and Performance of Biogas Microbiomes
Microorganisms, 2020 In this study the response of biogas-producing microbiomes to a profound feedstock change was investigated. The microbiomes were adapted to the digestion of either 100% sugar beet, maize silage, or of the silages with elevated amounts of total ammonium ...

Ammonium imidazolium dichromate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the crystal structure of the title compound, (C3H5N2)(NH4)[Cr2O7], the anions and cations are linked through N—H...O hydrogen bonds, resulting in a three-dimensional structure which contains three kinds of layers parallel to (001). One layer contains imidazole cations, the other two layers the ammonium cations and dichromate anions.

Ecology and physiology of anaerobic ammonium oxidizing bacteria.
Environmental Microbiology, 2016 Anaerobic ammonium oxidation (anammox) is a microbial process in which NH4 (+) is oxidized to N2 gas with NO2 (-) as an electron acceptor. The anammox process is mediated by bacterial members affiliated with the phylum Planctomycetes, which are ...

Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli
FEBS Open Bio, EarlyView.BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.

Nitric oxide‐forming nitrite reductases in the anaerobic ammonium oxidizer Kuenenia stuttgartiensis
FEBS Open Bio, EarlyView.Anammox bacteria remove fixed nitrogen from their environment via anaerobic ammonium oxidation (anammox) with nitrite as electron acceptor and dinitrogen gas as product. The first anammox step is the conversion of nitrite to nitric oxide by nitrite reductase.

FEBS Open Bio, EarlyView.Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...
