Question

A scientist observed a bactirial specimen obtained from mud in a swamp. The bacteria are producing hydrogen sulfide which creates a foul smell. What procell is likely to be generating

Answer 1

Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.

Step-by-step explanation:

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the work of bacteria to reduce sulfur compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc. In a swamp there is low oxygen availability and organic matter decays in this condition.

The sulfate reducing bacteria oxidizes the organic matter and releases Hydrogen sulfide.
