Auxin production, Ammonia production, Nitrogen fixation, Phosphate solubilization, Plant growth promoting activity


Several microorganisms have been isolated from various plant sources which serve to improve the plant growth. Such plant associated endophytes protect their host against environmental stress, increase the tolerance against pathogens and induce growth by nitrogen fixation, through phosphate solubilization and also by producing growth hormone like substances. The present study was to elucidate the role of selected nine Endophytic Bacterial Isolates in plant growth promotion. These selected endophytic bacterial isolates were screened for their plant growth promoting activities like phosphate solubilization, nitrogen fixation, ammonia production, and protease, cellulase activity. Out of nine endophytic bacterial isolates, five of them showed positive results for all biochemical activities. The step by step isolation of endophytic bacteria with the features of auxin activity and growth promoting activity can makes a better formulation for maximum yield of crop plants.
