英文摘要
Preventing mechanism of hydrogen sulphide (H_2S) emission from sediment to water by nitrate-accumulating sulphur oxidizing bacteria (Beggiatoa) was investigated in Tokyo Bay, and it was discovered that bioelectrochemical reactions with oxygen (O_2) are playing important role in addition to chemical reactions with iron oxides (FeOOH) and biological reactions with nitrate (NO_3^-) by Beggiatoa. Electric communication between distant chemical and biological processes in nature adds an entirely new dimension to our understanding of biogeochemistry and microbial ecology.
