ISOLATION AND SCREENING OF HEAVY METAL ABSORBING BACTERIA FROM THE INDUSTRY EFFLUENT SITES OF THE RIVER NAGAVALIAbstract
The present study was designed to evaluate the heavy metal absorbing potential of bacteria isolated from industry effluent sites of river Nagavali, Srikakulam Andhra Pradesh. From the effluent waste water three bacteria were isolated and confirmed as Staphylococcus aureus and Staphylococcus epidermidis and Staphylococcus saprophyticus after performing various biochemical tests. The heavy metal tolerant efficiency was determined by analyzing the growth of the bacteria in presence of heavy metal (Cu, Hg, Co and Zn) solution and their optimum tolerance was determined by measuring the optical density at 600nm after 24hr and 48hr of incubation. Staphylococcus aureus, Staphylococcus epidermidis and Staphylococcus saprophyticus were found to grow in heavy metal solutions.
