A deep‐sea sulfate‐reducing bacterium generates zero‐valent sulfur via metabolizing thiosulfate
Zero‐valent sulfur (ZVS) is a crucial intermediate in the sulfur geobiochemical circulation and is widespread in deep‐sea cold seeps. Sulfur‐oxidizing bacteria are thought to be the major contributors to the formation of ZVS.
