From a plant sugar to toxic hydrogen sulfide

In a doctoral research project conducted at the Department of Biology, researchers have described the degradation of the dietary sugar sulfoquinovose by anaerobic bacteria to toxic hydrogen sulfide for the first time—increased ...

What's behind smelly wine

Aging often improves the flavor of wine, but sometimes the beverage emerges from storage with an unpleasant smell. One of the prime culprits is hydrogen sulfide (H2S), which can give the affected wine an aroma of sewage or ...

Eco-friendly nanoparticles for artificial photosynthesis

Researchers at the University of Zurich have developed a type of nanoparticle by adding zinc sulfide to the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight—a ...

Sensor detects whiff of bad breath

Ever wish you could do a quick "breath check" before an important meeting or a big date? Now researchers, reporting in ACS' journal Analytical Chemistry, have developed a sensor that detects tiny amounts of hydrogen sulfide ...

Microbes with a reserve pack of sulfur

SUP05 bacteria are often found in places where there is really no basis for life for them. Researchers in Bremen have now discovered that they are even quite active there – possibly with consequences for the global nitrogen ...

What do Uranus's cloud tops have in common with rotten eggs?

Hydrogen sulfide, the gas that gives rotten eggs their distinctive odor, permeates the upper atmosphere of the planet Uranus - as has been long debated, but never definitively proven. Based on sensitive spectroscopic observations ...
