ABSTRACT

The paper deals with plant growth-promoting rhizobacteria and their capacities to boost the efficiency of phytoremediation processes applied on soil polluted by the industry. For this purpose, we chose a locality in the form of decontamination site in Ostrava, where ruderal plants were sampled. Such plants are generally regarded as hyperaccumulating with high production of biomass plants. Their root systems were confirmed for the occurrence of PGPR-bacteria, predominantly of the Pseudomonas genus. The results of the resistance tests showed an increased resistance towards lead which belongs among the dominant inorganic pollutants in the locality in question. The application of PGPR-rhizobacteria to support the growth of ruderal hyperaccumulating and high biomass plants is a prospective method to reduce environmental pollution caused by the industry and mining. Applying a correctly prepared PGPR-consorcium may boost the absorption of metals by plants from the environment and thus increase the natural phytoaccumulation capacities of the plants. Such plants may be subsequently used for the effective phytoremediation of sites contaminated by anthropogenic activities.
