CHAVEZ-RAMIREZ, B. et al. Growth and ionomic response of Sedum praealtum A. DC by the synergistic action of indole butiric acid and rhizobacteria in the arsenic and cadmium assisted phytoextraction.

Assisted phytoextraction involves the plant species and supplementary agents (chemical or biological amendments) participation to increase the contaminant bioavailability and accumulation and with the employ of ionomic biomarkers management; not only analyze the analysis of plants susceptibility to particular stress; it also achieves the evaluation of the absorption and mobilization of elements inside them. The present work evaluates the synergistic action between Pseudomonas sp. C2 and indole butyric acid in the assisted phytoextraction of As and Cd, by the growth and ionomic responses of Sedum praealtum A. DC. Ionomic profiles obtained as response of exogenous addition of As and Cd; suggest that roots of this plant species constitutes an important barrier to their accumulation and the synergistic relationship between As with Mo, Cu, Fe and Zn; showing a clear evidence that both supplementary agents promoted the grown of roots and the assisted phytoextraction.
