PGPB exhibiting multiple plant health and development
enhancing traits coupled with the excellent potential to lower
down the heavy metal stress in soils, may eventually find
wide-ranging applications in the development of bioremediation
strategies for heavy metal decontamination. In heavily
contaminated soils where the metal content exceeds the limit
of plant tolerance, it may be possible to treat plants with
PGPB thereby stabilizing, re-vegetating, and remediating
metal-polluted soils. In addition, the application of the heavy
metal resistant and plant-beneficial bacteria can be considered
as bioremediating tools with great economical and ecological
relevance.
