sulfide

The mice's consumption of oxygen and production of carbon dioxide dropped ten minutes after they began inhaling hydrogen sulphide and remained extremely low as long as the gas was administered.

Well, the current hypothesis is that these microorganisms produce a chemical, dimetho sulfide that interacts with the oxygen in the air, creating conditions that lead to the formation of the low thick clouds we observed.

Chondrules and inclusions in Allende are held together by the chondrite matrix, a mixture of fine-grained, mostly silicate minerals that also includes grains of iron metal and iron sulfide.

Bacteria feed on this oil and release hydrogen sulfide gas.

This gas is hydrogen sulfide, rises up and mixes with oxygen and the underground water that sits in the cracks and fissures in the limestone.

And when hydrogen sulfide reacts with the oxygen in the water, the result of that is sulfuric acid. OK?

As we said, these hydrothermal vents are releasing into the ocean depth, this intensely hot water, and here’s the thing, this hot water contains chemical called hydrogen sulfide and also a gas, carbon dioxide.

Now these bacteria actually combine the hydrogen sulfide with the carbon dioxide.

Well, they have this special organs that collect the hydrogen sulfide and carbon dioxide, and then transfer it to another organ where billions of bacteria live, these bacteria that live inside the tube worms.

The tube worms provide them with hydrogen sulfide and carbon dioxide and the bacteria, well, the bacteria kind of feed the tube worms through chemosynthesis.

Because they lack oxygen, marsh sediments are high in sulfides that are toxic to most plants.

Spartina has the ability to take up sulfides and convert them to sulfate, a form of sulfur that the plant can use; this ability makes it easier for the grass to colonize marsh environments.
