Boundary conditions for exploiting the cooperation of <i>Aminobacter niigataensis</i> MSH1 with <i>Piscinibacter</i> sp. K169 to support 2,6-dichlorobenzamide biodegradation in sand filters for drinking water treatment: role of cell density and organic carbon.

ABSTRACT: Aminobacter niigataensis MSH1 mineralizes the groundwater micropollutant 2,6-dichlorobenzamide (BAM) and is a candidate for bioaugmentation of sand filters in drinking water treatment plants (DWTP) to avert BAM-contamination. Piscinibacter sp. K169 is a sand filter isolate that improves MSH1-mediated BAM mineralization through a cooperative interaction, and co-inoculation of MSH1 with K169 is proposed as a strategy to support bioaugmentation with MSH1. In this study, boundaries regarding the initial population size and the supply of organic carbon resources determining the interaction between MSH1 and K169 in sand filter microcosms were explored. The cooperative interaction was only disturbed when initial cell densities of one of the two partners were 10⁴ cells/mL
