The accumulation of fixed biomass increases the observed growth yield of a nitrifying biofilm

Abstract

The observed growth yield (Y obs) of a nitrifying biofilm metabolizing ammonia in a continuous flow reactor was constant below a fixed biomass concentration of 40–50 μg COD-biomass cm−2. Beyond this range, an increased Y obs with the additional accumulation of fixed biomass could be due to a considerable accumulation of inactive materials within the nitrifying biofilm.
