Abstract
The main objective to conduct the study was to isolate and characterize the rhizobacteria and unravel their plant growth potential and biological control using various biochemical tests. The study focuses on isolation of Bacillus species related with two himalayan medicinal plant namely Diplazium esculentum and Clitoria ternatea. By cultivation dependent approach 8 bacillus isolates were obtained and further screened for various plant-growth promotion activities. Out of all the isolates only one strain was found to be positive for the production of indole acetic acid. The production of indole acetic acid during plant-microbial interaction is of immence importance because the IAA is a major phytohormone, which controls the plant growth and development. This positive strain will further be characterized based upon 16S phylogeny and will be checked in pots for its plant-growth promotion activity and for the successful development of a commercial bioformulation.
