Abstract: Nitrate is migrated into the sediment by Thioploca bacteria using a unique mechanism of concentrating nitrate in liquid vacuoles that make up more than 80% of the bacteria's cells. The mechanism involves hydrogen sulphide oxidation linked to the sediment's sulphur cycles. This bacteria exists in thick mats in the oxygen-minimum zone of the upwelling region off the Pacific coast of South America.
