Soil phosphatases play a major role in the mineralization processes of organic phosphorus. A phytase or myo-inositol hexakisphosphate phosphohydrolase (E.C. 3.1.3.8) effectively catalyzes the release of phosphate from phytate and phosphorylated compound. Phytase is derived from different sources such as bacteria and yeasts. The extracellular phytase producing bacteria was isolated from poultry and phytase production was screened. It was purified by ammonium sulphate fractionation of protein and dialysis followed by SDS-PAGE. The DNA from Bacillus megaterium was isolated using CTAB method. The maximum enzyme production was obtained in the 60th h at 37°C, pH 6.5 and 200 rpm shaking. The best carbon and nitrogen source was lactose 138 μg/mL and ammonium sulphate 124 μg/mL, respectively. The 16S rRNA gene sequencing was carried out for identification of positive bacteria. Pot experiment was carried out with Zea mays for phosphate utilization and accessed by root and maximum measurement was observed.
