Rhizobacterial inoculation modulates As uptake. Rice cultivar Seraceltik were germinated on water and transferred to 8-L system containing rice nutrient solution. After 21 days the plants were treated with natural isolates EA105 or EA106 with or without (5 μM) As(III) and incubated for 7 days. ICP-MS quantification of As content in roots (A) and shoots (B) of rice plants. Each treatment had three plants and repeated twice with similar results. Error bars indicate standard error. Different letters indicate statistically significant differences between treatments (Tukey's HSD).
