Abstract

Phytophilic bacteria with phytophilic properties and fixation of soil heavy (analogous) metals can promote plant growth and reduce plant heavy (analogous) metal content. To screen phytoproducing bacteria from the inter-root soil of vegetables grown in heavy (group) metal-contaminated farmland for their ability to reduce As and Cd content in vegetables. Pot experiments were conducted to verify the ability of the functional strains to reduce As and Cd uptake in spinach and green stem cabbage. Functional strains Burkholderia cenocepacia W1–9, Pseudomonas entomophila W1–25, Pseudomonas entomophila W1–51 and Bacillus sp. 51, Pseudomonas entomophila W1–25, Pseudomonas entomophila W1- 51 and Bacillus sp. W2–26. The four test strains had the ability to promote the growth of two leafy vegetables, reduce their uptake and utilisation of Cd and As and stabilise the soil environment, reducing the content of Cd and As in the active state in the soil environment.
