Nitrospira was always thought to compete
with anammox, by stealing its nitrite away.

Back at Princeton, Ward suspected that both processes were necessary,
with denitrification churning out the ammonium that
anammox then converted to nitrogen gas.
In the new study, the researchers found that both of these nitrogen «exit strategies» are at work in the oceans,
with denitrification mopping up about 70 percent of the nitrogen and
anammox disposing of the rest.
But
with the current discovery, it seems that Nitrospira was actually helping
anammox all along by providing it
with extra nitrite.
