In this present study total four bacterial isolates were obtained from 34 collected groundwater samples in 10th of Ramadan Sharkia governorate Egypt. These isolate were grown on nutrient agar supplemented with 1mgl of iron manganese and combination between them VV. Further testing of the bacterial isolates were grown on nutrient agar supplemented with different concentrations 2 4 5 6 7 8 and 9 mgl of iron and manganese. Out of four isolates one bacterial isolate no.83 has shown the resistance to heavy metals at maximum concentration of 8mgl. Selected isolate no.S83 was identified as Pseudomonas putida S83 according to Bergeys manual depending on morphological and biochemical characteristics. Transmission electron microscopy study of P. putida isolate no. S83 showed accumulation of heavy metal salts within and external to bacterial cells. P. putida S83 have higher removal efficiency of Fe2 94.5 and Mn2 94 at concentration 2 mgl and 96 hours.
