Desulfocapsa sulfexigens SB164P1 (DSM 10523) belongs to the deltaproteobacterial family Desulfobulbaceae and is one of two validly described members of its genus. This strain was selected for genome sequencing, because it is the first marine bacterium reported to thrive on the disproportionation of elemental sulfur, a process with a unresolved enzymatic pathway in which elemental sulfur serves ...

Gaseous mediators are important signaling molecules with properties that differ from other, larger signaling molecules. Small gaseous mediators readily cross cell membranes and can access sites on target molecules that would be inaccessible to bulkier molecules. They have a variety of signaling mechanisms, some well understood, some not. The family of gasotransmitters is growing, well known mem...

This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium. Key genes of known sulfide oxidation pathways are absent from the genome of D. alkaliphilus Instead, the genome contains all of the genes necessary for sulfate reduction, including a gen...

The emission of mercury from coal combustion has caused consequential hazards to the ecosystem. key challenge abating is explore highly efficient adsorbents. Herein, sulfur-functionalized carbon (S-C) was synthesized by using a molten-salt pyrolysis strategy and employed for removal elemental coal-combustion flue gas. An ideal pore structure, which favorable internal diffusion Hg0 molecule in c...

The vasodilator response of nitric oxide (NO), hydrogen sulfide (H2S) and sulfur dioxide (SO2) were studied todetermine the significance of the actions and interactions of these gasotransmitters for controlling aortic tone in rats. The isometric tension of five separate sets of experiments was recorded. Sodium nitroprusside (SNP; NO donor), sodium disulphide (Na2S; H2S donor), SO2 derivatives a...

Among the air pollutants, sulfur dioxide has been given special emphasis for posing dangers to the environment. SO2 emissions in the air have harmful effects on human health and the environment. Respiratory diseases and exacerbation of heart diseases are among dangerous symptoms for human health, especially when high concentrations of SO2 are emitted. Therefore, in the present study, a wide var...

Extreme toxicity, corrosiveness, and volatility pose serious challenges for the safe storage and transportation of elemental chlorine and bromine, which play critical roles in the chemical industry. Solid materials capable of forming stable nonvolatile compounds upon reaction with elemental halogens may partially mitigate these challenges by allowing safe halogen release on demand. Here we demo...

Graphene is an allotrope of carbon apart from graphite, diamond, fullerene and carbon nanotubes. Because graphene has unique mechanical, structural, thermal and electrochemical properties and can present the stability characteristics of these features, it becomes two-dimensional (2-d) materials which can alter three-dimensional (3-d) carbon nanotubes composite materials and has important resear...
