ABSTRACT: Bioaugmentation consists of adding selected strains of microorganisms with known capabilities to a biological process to improve performance. In this study, laboratory-scale completely stirred tank reactors were bioaugmented with nitrifying bacteria while operated under high-stress conditions for the nitrifiers: a 2-day solids retention time (SRT) at 22 degC or a 5-day SRT at 4 degC. Intensive sampling was carried out to document the effects of the bioaugmentation. To quantitatively...
