The present study was designed to evaluate the heavy metal absorbing potential of microbes isolated from paint industry effluent. The effluent waste water was used as the source sample, after screening morpho-metrically ten strains were cultured and sub cultured to achieve the pure discrete colonies. Out of ten discrete colonies were found to have the heavy metal absorbing ability. These two bacteria were identified as Micrococcus luteus and Staphylococcus epidermidis respectively. 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. Micrococcus luteus and Staphylococcus epidermidis were both observed as heavy metal tolerant bacteria further these two microbes were subjected to sensitivity testing against commercially available antibiotics.
