Abstract
We developed a joint bioaugmentation and biostimulation approach for the clean up of soil contaminated with high (168.7 and 337.4 microg g(-1)) concentrations of the herbicide atrazine (2-chloro-4-(ethylamino)-6-isopropylamino-s-triazine). Pseudomonas sp. strain ADP (P. ADP) was used for bioaugmentation (approximately 10(7) cells g(-1) soil), and citrate (concentration range 5.8-40 mg g(-1) soil) and succinate (6.2-30.8 mg g(-1)) were used for biostimulation. The study soil had indigenous potential for atrazine mineralization (54.4 +/- 2% of 168.7 microg g(-1) mineralized after 67 day), but rapid mineralization only took place after a prolonged acclimation phase (approximately 28 days). Inoculation with P. ADP alone resulted in a limited improvement in mineralization (e.g., 30.6 +/- 1% mineralization of 168.7 microg g(-1) of atrazine in inoculated soil cf. 40 was required for maximal atrazine mineralization. We suggest our observations may be used as a framework for rational bioremediation of field soils contaminated with atrazine.
