Flowers of sulfur tests

The "flowers of sulfur" test typically refers to a method used in microbiology and analytical chemistry to detect the presence of sulfur compounds or to identify specific microorganisms that produce sulfur compounds, particularly hydrogen sulfide (H₂S). One of the common applications of this test is in identifying certain bacteria, like those from the genus *Salmonella* or *Proteus*, which can produce hydrogen sulfide in a culture medium.
