ISOLATION AND CHARACTERIZATION OF PSEUDOMONAS RESISTANT TO HEAVY METALS CONTAMINANTS

Abstract

In the present study total eight heavy metal resistant Pseudomonas sp 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 50µg/ml to 350µg/ml. All isolates showed multiple tolerances to heavy metal and were multi antibiotic resistant. Heavy Metal Tolerance Test indicated maximum microbial tolerance of Pseudomonas sp (Ps-6) to Copper (300 µg/ml) and lowest to Chromium (60 µg/ml).
