Online published on 2 December, 2023. Abstract Phosphate Solubilizing Bacteria (PSB) present in the rhizosphere play a vital role in increasing the bioavailability of soil phosphate for plant through solubilization and mineralization. The present study aimed at analysing PSB from different rhizospheres and testing isolates on growth of mung bean plant at different medium with the future prospects. PSB were isolated by spread plate technique using Pikovskaya's medium (PVK) and further identified using appropriate biochemical test. Pot experimentswereusing for green gram plant rhizosphere soil to determine the efficiency of the isolated PSB on growth of mung bean. The total number of 6 microbial isolates with halo-zone of phosphate solubilization more than 5mm were isolated from the various rhizosphere soils samples. All of the 6 isolates showed in the efficiency to phosphate solubilizing bacteria (Pseudomonas). All over the results were significantly.Therefore, they can be used as biofertilizer to enhance the availability of P in the soil and improving the efficiency of mung bean and other crops as like black gram, pea and gram.
