Mixed liquid cultures of ectomycorrhizal fungi were incubated in the presence of common soil contaminants (aldrin and PCBs) and three commercial surfactants (Surfonic (R) L24-9, Surfonic (R) T-20, and Rexophos JV-05-015). Two surfactants (Surfonic (R) L24-9 and Surfonic (R) T-20) significantly increased hyphal growth under carbon-limiting conditions, thus implying surfactant biodegradability. All three surfactants increased the hyphal uptake of contaminant-derived radiolabel during a 10-day incubation. In addition, surfactants enhanced radiolabel uptake during an extended 30-day incubation, while hyphal growth slowed considerably after ten days. Results of this experiment provided evidence that surfactant addition may be a useful augmentation to mycorrhizae-mediated phytoremediation.
