Bio-fertilizers are cultured microorganisms with suitable carrier material used in broad-spectrum for enhancing the plant growth and productivity. The critical input in Bio-fertilizers is as such the microorganisms. In our study the bio-fertilizer samples of IFGTB (Non-commercial) and IIHR (Commercial) institutions were studied for their Viability, Cultural, Morphological and Biochemical characterization. Serial dilution technique was done to test the viability of Liquid formulation of N-fixers, Phosphobacteria and Potash Mobilizer microorganisms. The results showed that, viability of Azospirillum, Phosphobacteria and Potash mobilizer were recorded with highest number of cells in IFGTB developed bio-fertilizers, i.e., log105.43, log106.13 and log106.65 respectively when compared to commercially obtained samples at 10-7 dilution and these microorganisms (PGPRs) were studied for their cultural and morphological characters like, size, shape, motility etc. in addition to biochemical characterization. The results showed that, Azospirillum, Azotobacter, Phosphobacteria and potash mobilizer showed positive results for Amylase production, Catalase and Citrate production tests etc. and negative results for oxidation and fermentation of glucose and peptone utilization.
