Activity-Based Cell Sorting Reveals Resistance of Functionally Degenerate <i>Nitrospira</i> during a Press Disturbance in Nitrifying Activated Sludge

Abstract
Nitrogen removal from activated sludge wastewater treatment systems is an energy-intensive process due to the large aeration requirement for nitrification. This energy footprint could be minimized with engineering control strategies that wash out nitrite-oxidizing bacteria (NOB) to limit oxygen demands.
