Isolation and Characterization of PGPR from Paper Mill Effluent Infested Area

Paper and pulp industry are considered as 17th most polluting industry due to its highly coloured and toxic wastewater discharge in the environment. A number of heavy metals get mixed within the agricultural soil through the paper mill discharge. These heavy metals are potent phytotoxic and they have huge negative impact on plant health. To minimize these impacts and to improve crop health deliberate application of chemical fertilizers is very common in present days but these chemical fertilizers are destroying the soil and plant health tremendously. In this situation rhizosphere researches suggest the concept of the application of PGPR. The group of root colonizing bacteria which enhance plant growth and development are called Plant Growth Promoting Rhizobacteria PGPR . This group of bacteria improve plant's growth by direct as well as indirect mechanisms. These mechanisms involve IAA production, siderophore production, soil structure formation, decomposition of organic matter, solubilization of minerals, degrading organic pollutants, biocontrol of seed borne pathogens etc. In present study we have focused on isolation and characterization of PGPRs from paper mill effluent infested soil.
