Abstract

Living without oxygen Several foraminiferal protozoa species grow in anoxic zones in marine sediment, but the type of anaerobic respiration that sustains them was not known. These organisms have now been found to accumulate nitrate intracellularly at concentrations more than 500 times the environmental values. The nitrate substitutes for oxygen in these anoxic habitats. The large amounts of nitrate that accumulate may even allow them to 'hold their breath' for more than a month.
