Abstract :Heavy metals are present in the soil, geologic and anthropogenic activities that increase the concentration of these elements to amounts that are harmful to both plants and animals. The use of metal- resistant plant growth promoting Rhizobacteria (PGPR) constitutes an important tool for the tolerance of the plants to heavy metals which helps in promoting root and shoots growth. In this study, bacterial communities from two industrial sites were characterized in order to isolate, and identify cadmium resistant bacteria. Four cadmium-resistant bacteria were isolated from two soil samples from heavy metal-contaminated sites, and were evaluated for their plant growth promoting characters. Bacterial strains showing positive results of PGPR

characteristics may be utilized to augment plant growth and suppress plant diseases. The study provides an insight in the development of phytoremediation in cadmium contaminated soil.

Keywords: Cadmium, Bacteria, Isolation, MIC, PGPR.
