**4. Conclusion**

In this study, *Bacillus megaterium* improved the best results for growth was in 48 h while in two months, had the same growth each five and twenty five concentration. The degradation rate % ability was the best in (5,25) ppm/two months reached (70-71)%. The Glyphosate degradation ratio% increasing equally with the increasing the incubation to two months,the best was for five and twenty five ppm, each the HPLC and Degradation ratio%. The conclusion is the *B. megaterium* utilized Glyphosate as supplier for elements sulfur, carbon, nitrogen and phosphorus and cultivated highly from culture could be well exploited for biodegradation from its pollutants sites.
