Abstract

Fifty groundwater samples were collected from five different localities in El-Sharkia Province, Egypt during 2014.Leptothrix discophoraW19was isolated from the collected ground water samples, purified and grown on nutrient agar media supplemented with 1mg/L of each of iron and manganese. Conventional identification of Leptothrix discophora W19isolate following the key of Bergey's manual. Standard water containing different concentrations of Fe+2 and Mn+2 had been examined for both tested metals removal capacity using Leptothrix discophora W19 as a bioleaching. The biological system for iron and manganese removal had provided overall removal efficiency up to 95.25% and 95% for iron and manganese respectively. Key words: Leptothrix discophoraW19, Groundwater, Iron, Manganese, Biological treatment, Bioleaching.
