Intestinal Sulfate Reduction to H2S by Sulfur-Reducing Bacteria
In this video, we will explore the source of the major cause of the smell of flatulence. Intestinal sulfate-reducing bacteria reduce sulfate to hydrogen sulfide (H2S). We will see the biochemical pathway here and how it is coupled to...
