Heterogeneous reaction of carbonyl sulfide (OCS) on magnesium oxide (MgO) under ambient conditions was investigated by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), quadrupole mass spectrometer (QMS), and density functional theory (DFT) calculations. It reveals that OCS can be catalytically hydrolyzed by surface hydroxyl on MgO to produce carbon dioxide (CO2) and...

The dynamics of sulfate reduction, methane production, and denitrification were investigated in a permanently waterlogged alder swamp. Molybdate, an inhibitor of sulfate reduction, stimulated methane production in soil slurries, thus suggesting competition for common substrates between sulfate-reducing and methane-producing bacteria. Acetate, hydrogen, and methanol were found to stimulate both ...

Introduction: Most commercial surfactants used for cleaning (as detergents (are part of xezenbiotic compounds. These compounds and products due to its toxic effects on aquatic organisms may interfere with hormonal system and consequently change the echo system. Since the biodegradation of those compounds are weak, ordinary methods are unable to break down conventional purification. Therefore, t...

The distribution of thermophilic marine sulfate reducers in produced oil reservoir waters from the Gullfaks oil field in the Norwegian sector of the North Sea was investigated by using enrichment cultures and genus-specific fluorescent antibodies produced against the genera Archaeoglobus, Desulfotomaculum, and Thermodesulforhabdus. The thermophilic marine sulfate reducers in this environment co...

Thiosulfate formation and biodegradation processes link aerobic and anaerobic metabolism of cysteine. In these reactions, sulfite formed from thiosulfate is oxidized to sulfate while hydrogen sulfide is transformed into thiosulfate. These processes occurring mostly in mitochondria are described as a canonical hydrogen sulfide oxidation pathway. In this review, we discuss the current state of kn...

The title compound, 2C5H7N5(2+)·2HSO4(-)·SO4(2-), was synthesized from adenine and sulfuric acid. The asymmetric unit contains two diprotonated adeninium cations, two bis-ulfate anions and one sulfate anion. The crystal structure is stabilized by classical N-H⋯O and O-H⋯O hydrogen bonds, and weak C-H⋯O and C-H⋯N hydrogen bonds, generating a three-dimensional network.

In the title compound, C(3)H(8)N(6) (2+)·SO(4) (2-), the melaminium cations and sulfate anions are inter-connected by N-H⋯N and N-H⋯O hydrogen bonds, forming a layer in the (101) plane. The layers are connected through multiple hydrogen bonds and π-π stacking inter-actions (centroid-centroid distance of about 3.4 Å).
