Abstract: Two biofertilizer agents, <i>Azospirillum amazonense </i>A10 and <i>Bacillus megaterium </i>P7, alone and in combination increased the grain yield of rice in autoclaved soil by 103-256% over control. Colonies of <i>A, amazonense </i>and <i>B.</i> <i>megaterium </i>were distinguished from the contaminant phosphate solubilizing bacteria (PSB) and Azospirilla colonies in the respective media based on colony morphology, colour and thickness of clearing zone, Population densities of <i>A,</i> <i>amazonense </i>and <i>B. megaterium </i>were found to be 2.6 x 108 and 2.9 x 108 CFUg .] soil, respectively at 48 day post transplanting. Protein and antibiotic resistance profiles of the inoculated and reisolated <i>A. amazonense, B.</i> <i>megaterium </i>and the contaminant colonies with the pure cultures indicated that the isolates were able to establish in the rice rhizosphere with the resultant enhancement of plant growth and yield.
