Sulfate reduction

Sulfate reduction is a natural process where certain bacteria break down sulfur-containing compounds, like sulfate, in environments such as sediments or water. These bacteria use sulfate as an energy source, converting it into hydrogen sulfide, a gas with a distinct rotten-egg smell. This process plays a vital role in the Earth's sulfur cycle and influences the chemistry of soils, sediments, and water bodies. It often occurs in oxygen-free conditions and is essential for the recycling of sulfur in ecosystems.
