Water pollution s the imajor universal threats for environment pollution. The industrial effluent iand untreated sewage water is discharge n to the water ibodies, which creates a serious problem to the living systems. Gomti River is polluted with different hazardous contaminants including heavy metals like iron, cadmium, zinc etc. As iron is essential component for good health of living organisms, but the ingestion of large quantities of iron results in haemochromatosis. This problem has lead to study the biosorption of iron. The present study is carried out to isolate microbes from the metal contaminated zone of Gomti river. The isolation of microbes was done to study the resistance patterns of microbe against iron metal and to evaluate iron biosorption potential. Samples were collected from five locations namely Hussainabad, Pakkapul, Hanuman setu, Lakshman mela ground, Baikunth dham . The parameters like total suspended solids (TSS), total dissolved solid (TDS), pH, hardness, dissolved oxygen (DO), chlorine, total coliforms and heavy metals like iron, cadmium, copper and arsenic were determined. High concentration of Iron (Fe) contamination was observed in these locations. The isolation of bacteria, fungi and yeast was performed by using standard plate techniques on specific media having concentration of iron. Among these three microbes, only three bacterial were present . Amongst these three the isolated bacterial strain was used identified as E coli, and used for the biosorption of iron. The results of present study revealed that the minimum % biodegradation of concentration of iron after 5 days was 6.10 ( GWS2)and maximum was 14.9 (GWS1) ,after 10 days minimum %35.37 (GWS2) and maximum was 47.62 (GWS1) and after 15 days minimum % was 68.29 (GWS2) and maximum was 76.19 (GS1) The maximum reduction of iron was observed over a period of 15 days . These results indicate that the isolated E coli are potential strain for iron biosorption.
