Biogeochemistry: Symbiotic bacteria split redox reactions over long distances
Department: Science & Technology
Keywords: redox reactions, bacteria, symbiosis

Like power lines, bacteria send myriad electrons across long distances to satisfy their community's energy demands, a new study shows. The research, led by Lars Peter Nielsen at Aarhus University, in Denmark, reveals that bacteria living deep within anoxic layers of marine sediments oxidize hydrogen sulfide to produce a pool of electrons that travel to bacteria at the sedimen's surface. There, the surface bacteria use the electrons to reduce oxygen . . .
