What Are Sulfate-Reducing Bacteria?
Sulfate-reducing bacteria (SRB) are a group of microorganisms that reduce sulfate (SO₄²⁻) to hydrogen sulfide (H₂S) in anaerobic or low-oxygen environments. These bacteria are widely distributed in nature, particularly in water, soil, sediments, and extreme environments. SRBs play a crucial role in the sulfur cycle in Earth’s ecosystems and have significant applications and effects in …
