Abstract
Application of Pseudomonas rhizosphere bacteria promoting the growth of various agricultural plants was shown to eliminate to a significant extent the phytotoxicity of oil-contaminated soil for oat plants in greenhouse pot experiment and to have the same efficiency as a sorbent consisting of hydrolyzed lignin. A combined use of bacteria and sorbent did not enhance their positive effects. Inoculation with bacteria resulted in a significant decrease in the uptake of Pb by barley plants, their increased resistance to its toxic action and a decrease of Cd uptake in a series of greenhouse pot experiments on a soil contaminated with water-soluble compounds of these heavy metals.
