Examining the fate of released Pseudomonas putida F1 in rhizosphere environments
- Kansas State Univ., Manhattan, KS (United States)
Bioremediation, especially plant-based bioremediation, is receiving increasing attention because compared to traditional soil and groundwater remediation techniques, it is rapid, safe, and cost-effective. A soil microcosm study was conducted to see the fate of released bacterial strain Pseudomonas putida F1 in soil. Although the P. p F1 population died off to low levels within the experimental period, the presence of alfalfa and poplar trees helped the survival of P. p F1 in soil. The P. p F1 populations were significantly higher (p = 0.05) in soil samples from the poplar tree soil microcosms than from unplanted control soil microcosms. There was no significant difference observed between soil microcosms planted with alfalfa and unplanted control. The better survival of P. p F1 in planted soil is due to the rhizosphere effect, and therefore, is dependent on the root density in soil. This study shows the beneficial effect of vegetation on the survival of a laboratory cultured strain under conditions close to field condition.
