The restricted metabolism of the obligate organohalide respiring bacterium Dehalobacter restrictus: lessons from tiered functional genomics

Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt

Dehalobacter restrictus strain PER-K23 is an obligate organohalide respiring bacterium, which displays extremely narrow metabolic capabilities. It grows only via coupling energy conservation to anaerobic respiration of tetra- and trichloroethene with hydro ...

Formation of N-nitrosamines from chlorination and chloramination of molecular weight fractions of natural organic matter

Urs von Gunten, Ina Kristiana

N-Nitrosamines are a class of disinfection by-products (DBPs) that have been reported to be more toxic than the most commonly detected and regulated DBPs. Only a few studies investigating the formation of N-nitrosamines from disinfection of natural waters ...

Comparison of the photocatalytic efficiencies of bare and doped rutile and anatase TiO2 photocatalysts under visible light for phenol degradation and E. coli inactivation

László Forró, Andrzej Sienkiewicz, Klara Hernadi

This study aimed at comparing the photocatalytic efficiencies of various TiO2 based photocatalysts for phenol degradation and bacteria inactivation under illumination with visible light. Commercial undoped anatase and rutile (both from Aldrich), Aeroxide P ...

A single-cell view of ammonium assimilation in coral-dinoflagellate symbiosis

Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp

Assimilation of inorganic nitrogen from nutrient-poor tropical seas is an essential challenge for the endosymbiosis between reef-building corals and dinoflagellates. Despite the clear evidence that reef-building corals can use ammonium as inorganic nitroge ...

Modulating dye E(S+/S*) with efficient heterocyclic nitrogen containing acceptors for DSCs

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aswani Yella

Acceptor motifs based on nitrogen containing heterocycles have been synthesized for use in dye-sensitized solar cells (DSCs). Through the selective addition of nitrogen atoms and increased conjugation of the nitrogen containing heterocycles the excited-sta ...

Supramolecular polymers based on dative boron–nitrogen bonds

Kay Severin, Nicolas Luisier, Erin Sheepwash

Heteroditopic monomers containing an arylboronate ester and a dialkyl-4-aminopyridine group aggregate via dative boron–nitrogen bonds to give main chain supramolecular polymers. The degree of polymerization can be tuned by changing the electronic and steri ...

High nitrogen deposition alters the decomposition of bog plant litter and reduces carbon accumulation

Alexandre Buttler, Luca Bragazza, Jonathan Habermacher

Bogs are globally important sinks of atmospheric carbon (C) due to the accumulation of partially decomposed litter that forms peat. Because bogs receive their nutrients from the atmosphere, the world-wide increase of nitrogen (N) deposition is expected to ...

Glasshouse vs field experiments: do they yield ecologically similar results for assessing N impacts on peat mosses?

Alexandre Buttler, Edward Mitchell, Luca Bragazza

Peat bogs have accumulated more atmospheric carbon (C) than any other terrestrial ecosystem today. Most of this C is associated with peat moss (Sphagnum) litter. Atmospheric nitrogen (N) deposition can decrease Sphagnum production, compromising the C seque ...

Effects of carbonate on the electrolytic removal of ammonia and urea from urine with thermally prepared IrO2 electrodes

Christos Comninellis, Véronique Amstutz, Agnieszka Kapalka, Kai Udert

Recent studies have shown that electrolysis can be an efficient process for nitrogen removal from urine. These studies have been conducted with urea solutions or fresh urine, but urine collected in NoMix toilets and urinals has a substantially different co ...
