Rhizobacteria isolated from the rhizosphere of PCP tolerant maize plant were investigated for establishment of lac Z marked strains of PCP degrading bacteria in the rhizosphere of maize (Zea mays) under green house condition. The identities of the isolates were determined by 16S rRNA gene sequencing as Enterobacter asburiae (MAZ1) and Pseudomonas (MAZ2). Both the lac Z marked strains were able to survive in rhizosphere of maize under greenhouse conditions and maintained a population of about 104 g”1 of rhizosphere soil up to 60 days study period. Positive effect of inoculation with PCP degrading bacteria on plant length and biomass were observed. Out of two, PCP degrading Pseudomonas sp. MAZ 2 was found to possess higher root colonization ability and plant growth promoting potentials.
