Abstract

In the present study total eight heavy metal resistant E. coli were isolated from sewage of industrial
effluents from waste water treatment plant of Paonta Sahib H.P. India, against chromium, copper,
nickel, cadmium. All the isolates exhibited high resistance to heavy metals with minimum inhibitory
concentration (MIC) for heavy metals ranging from 50 μg/ml to 450 μg/ml. All isolates showed multiple
tolerances to heavy metal and were multi antibiotic resistant. Heavy Metal Tolerance Test indicated
maximum microbial tolerance of E. coli (Ec-7) to Chromium (400 μg/ml) and lowest to Copper (60
μg/ml).
