Niche creation improves bioaugmentation of an organic micropollutant degrader in oligotrophic waters.

ABSTRACT: Bioaugmentation of sand filters is an alternative process for eliminating organic micropollutants in drinking water treatment. Bioaugmentation resembles an invasion process and niche availability is a prime determinant for successful invasion. This is particularly relevant for bioaugmentation of oligotrophic environments where organic micropollutants (OMPs) hardly provide a selective C-source and exploitative competition for the scarce intrinsic organic carbon exists between inoculated OMP-degraders and resident microbiota. Building on microbial invasion theories, we tested the hypothesis that the success of bioaugmentation and associated OMP degradation can be enhanced through niche creation by supplying a selective carbon source for the introduced degrader.
