The present work was designed to evaluate the bioaugmentation potential of directly isolated bacterial species on heavy metals deposited due to leachate pollution of soil. Tailor-made microbial formula used as bioaugmentation agents consisted of nine bacterial species of different classes: γ-proteobacteria (4), α-proteobacteria (1), bacilli (2) and actinobacteria (2). Calculated removal efficiency of the potential bioaugmentation agents was 86, 73 and 71 % for Cu, Zn and Pb, respectively, when only three of the bacterial species (Bacillus thuringiensis,Lysinibacillus sphaericusandRhodococcus wratislaviensis) were used. The data are suitable for assessing the synergistic effect of microbes on the reduction of extractable heavy metals in contaminated soil, and optimizing their energy flux.
