Rapidly increasing worldwide industrialization has led to many environmental problems by the liberation of pollutants such as heavy metals. Day by day increasing metal contamination in soil and water can be best coped by the interaction of potential plant growth promoting rhizobacteria for plant growth. The effect of plant growth promoting rhizobacteria (PGPR) treatment on growth of chilli plant subjected to heavy metal stress was evaluated. Growth of chilli plant was examined with inoculation of two isolated PGPR (Lysinibacillus varians and Pseudomonas putida) under cadmium (30 ppm), lead (150 ppm) and the combination of heavy metal (Cd+Pb) stress condition. Among these two bacteria L. varians produced slightly better plant growth enhancement. Different growth parameters of chilli plants were reduced under heavy metal stress. Whereas, Cd and Pb tolerant PGPR inoculation, in root associated soil, enhanced plant growth development under test heavy metal contaminated soil. So, these PGPRs may easily be used as bio-fertilizers which will nullify the adverse effect of heavy metal on plant growth.

The review summarizes literature data and the results of the authors own research on the agronomically useful group of soil microorganisms stimulating plant growth (plant-growth-promoting rhizobacteria - PGPR bacteria). PGPRs have great potential for plant growth promoting as they control pest and disease and have been considered important in sustainable agriculture. PGPR includes a promising group of bacteria that live on the surface and inside the roots of agricultural plants. They possess a number of positive properties such as fixation of molecular nitrogen of the atmosphere, decomposition of harmful chemical compounds, synthesis of substances of a hormonal nature, are able to transform difficult phosphorus soil compounds, and also prevent or reduce the growth of phytopathogens due to the ability to synthesize substances with bactericidal and fungicidal effects, as well as competition for ions iron, without which the growth of phytopathogens is difficult. In addition, PGPR bacteria provide plant resistance to adverse environmental factors: heavy metal pollution of the soil, soil salinization, and drought. Under stress caused by heavy metal contamination of the soil, PGPR bacteria enhance plant survival. Data are presented showing the prospects of using these microorganisms in the development of technologies of ecological farming in order to increase plant productivity, biocontrol over the development of plant diseases, reduce the chemical load on the soil, increase its fertility.
